Choosing And Planting Your
Plants Part 2
Perennial & Annual
Grasses
While most of us are adding
grasses to the landscape that are perennials, there are also
some annual members of the family to look to for color and
interest. These include the small cloud grass, Agrostis
nebulosa, Big Quaking Grass, Briza maxima; Job's tears, Coix
lacryma-jobi; Rabbit's tail grass, Lagurus ovatus; and my
favorite the Purple Fountain Grass, Pennisetum setaceum
'Cupreum'.
If you are looking for small grasses in the
landscape consider bulbous oat grass, a white and green
variegated plant growing 12 to 18 inches in heigh. Side oats
grama, is a 2 foot tall plant with an arching growth habit,
that is very drought tolerant. And if moist soil is a problem,
consider one of the ornamental sedges (no, not nutsedge).
Leatherleaf sedge has coppery brown foliage year-round and is
a great border plant. Japanese sedge has some interesting
plant variegation and makes an attractive arching
mound.
Another neat plant is the dwarf blue fescue,
Festuca ovina 'Glauca'. It forms dense tufts of blueish green
plants, that makes an interesting ground cover or low border
to the garden. Bearskin feskue looks like a little green
porcupine in the garden, with golden spikes forming in the
center.
Annuals
Pansies
As the leaves begin falling, and our flowers start to fade
away, many gardeners put their gardens to bed for the winter
months. The idea of months without flowers seems a waste,
especially when we can have an outstanding display of color
from pansies all winter long. So instead of ending your
gardening for the year, begin your winter gardening with a
planting of pansies.
Pansies, come in a variety of
sizes, colors and types. They come in blues, reds, yellows,
white, orange, pink and purple. There is even a black variety.
There are solid colors without faces, to bi-colors with
contrasting faces, to blended colors, giving you a mix of
colors in each bloom. Intense breeding has developed flowers
that can get as large as four and a half inches across, on
lovely green foliage. It is hard to believe that these large,
brightly colored flowers are descendants of the quiet,
diminutive woodland violets.
Flowers
The flowers have a velvety texture and bloom over a long
period of time. They also last quite well as a small nosegay
or bouquet indoors. To keep the plants blooming, be sure to
dead-head —remove spent flowers as they decline. Pansies
thrive in cool weather, and will bloom for you from now until
hot weather causes them to decline next summer. Plant them in
a well-drained locatio n with moderately rich soil. They will grow in full
sun to partial shade. Those in full sun will fade away sooner
in the summer, but by then you have plenty of other plants to
replace them with.
Varieties and Colors
When it comes to varieties of pansies the list continues to
grow each year. Some of the most common classes of pansies
include Majestic Giants, which are one of the largest classes
of flowers, and the first pansy to be awarded an AAS —
All American Selection. Almost all varieties in this series
have the traditional dark blotch or face, and they come in
blue, purple,white, yellow and red. The Crystal Bowl series of
pansies are bright flowers which are clear colors (without
faces or blotches). The flowers are smaller, but there are
lots of them--these plants are very floriferous. Colors range
from white to yellow, true blue, rose, orange, violet and a
scarlet color. The Crown series of pansies are also clear
colors with slightly larger flowers ranging in color from
orange, red, white, yellow and blue.
Some unique types
of pansies include the Imperial Antiques which give soft,
blended colors. Each flower changes subtly from opening to
maturity. Another interesting series is the Joker series. One
interesting combination is Jolly Joker F2 Hybrid, it combines
an intense orange lower petals with a deep purple (almost
brown) upper petals. The Joker Light Blue has an outstanding
flower with a light purple outer color with a white band
leading to a dark purple blotch. The list could go on and on,
with new intense shades and mixtures each year. Go visit your
local nursery and see what is available that you like.
Pansies can be planted in a mix of colors, or for a
really dazzling display, in a single color. Plant the
individual plants four to six inches apart. Mass them together
wherever possible. They make a great companion planting for
spring flowering bulbs. Simply dig up the bed, plant the bulbs
first, cover them with soil, then plant the pansies on top.
The spring bulbs will come up right through the pansy
plantings for even more color in the
spring.
Container Plantings
Pansies also make ideal container plantings. If you live in
an apartment or condominium, don't think that you are excluded
from planting pansies. Plant a container full for your deck,
patio or front porch. Regular watering will need to be
included in their care--even when it is cold. It is especially
important prior to a heavy freeze. They don't need to be
saturated, but they do need to be
moist.
Fertilizer
Requirements
Fertilize pansies regularly all season long. Fertilize at
planting and during any warm spell throughout the winter. They
respond well to blood meal, but several gardeners have also
attracted wild animals to their pansy plantings by using it.
If you want to use blood meal, incorporate it into the soil
lightly. Be careful not to be too heavy handed, since it is a
high nitrogen fertilizer. Any commercial fertilizer will work
well also.
Bulbs
There are many who want to have a beautiful garden with
little effort. While the old adage: ' if it sounds too good to
be true, it probably is', usually applies; in the case of
bulbs, we get a break. You can simply dig a hole, plant a bulb
and sit back and wait for the flowers to come. It is the story
of the ugly duckling turning into a swan. In a manner of
months, these small, non-descript brown things turn into
glorious displays of flowers, with minimal effort, and in many
cases, they will continue to flower, year after
year.
By definition, a true bulb is a modified leaf
bud, consisting of a basal plate, short thick stem and fleshy
scales. It contains all plant parts and serves as a storage
organ. But for now, lets just lump all underground storage
organs as bulbs. This will include the corms, rhizomes, tubers
and pips. If you plant it in a dried, bulbous state, and wait
for the leaves and flowers to appear, we can give it the name
"bulb". Do consider that when you buy your bulbs, everything
is already contained inside it-the flowers, the leaves and the
stems. Therefore, the larger the bulb, the larger the flower
will be, and it should bloom its first season in the ground.
Whether or not it blooms the next year will be determined by
the care it gets while it is growing. Once its seasonal cycle
is complete, everything is once again set for the following
season.
There are two main classes of bulbs —
spring blooming and summer blooming. Summer bulbs are still
growing in our gardens and are preparing for their dormant
season, while spring bulbs are just being planted. Some of our
bulbs are hardy and can stay in the ground year-round, while
others do need to be lifted and stored for the
winter.
Summer bulbs which can stay in the garden include
cannas, lilies, Liatris, elephant ears, peonies, crocosmia,
and lycoris (the surprise lilies and Naked Ladies). Summer
bulbs with marginal hardiness include gladiolus, dahlias,
calla lilies and tuberose. Non-hardy bulbs which should be
lifted and stored for the winter if you plan to keep them
include caladiums, achimenes, and many of the amaryllis. To
store the bulbs, lift before or immediately after a killing
frost, let them air dry for a few days. Cut the old foliage
off, shake off excess soil, and place in a cool dry place in a
cardboard box, onion sack, etc. — not plastic. Replant in
the spring after all chances of frost have passed.
For
hardy spring bulbs, planting season is upon us. While the more
common bulbs include daffodils, tulips, crocus and hyacinths,
there are more options. Within the individual bulb groups
there are options-sometimes too many to choose from. With
careful selection you can start with snowdrops and crocus in
January and end with flowering onions in June.
When
planting bulbs, grouping them together in clusters will have a
stronger impact than a single row of bulbs. Grouping them by
season of bloom and color will also help. A mass planting will
make a huge impact in the spring, and they can easily be
planted under your winter annual plantings of pansies, violas
and kale. The bulbs will come up around them and add to the
seasonal color display. Unless you are growing the bulbs as
annuals, and replanting each season, consider the foliage
needs after blooming.
All spring blooming bulbs require
a minimum period of growth following bloom, which should last
at least six to eight weeks. While bone meal is the staple
fertilizer at planting — (and remember when we plant we
cannot alter flower size, we are simply aiding in root
establishment,) bulbs do like a more complete fertilizer
during the growing season. They aren't picky and it isn't hard
to do. Simply scatter some complete nutrition — 13-13-13
or whatever you have on hand will work fine, around the bulbs
when the foliage is well established but before they begin to
bloom.
You can also use a light application as soon as
they finish flowering. Allow the foliage to grow healthy for
at least six weeks following bloom. While some gardeners do
allow the foliage to begin yellowing before removal, that can
often take months-in a good growing year. That isn't
necessary, but it also won't hurt. Do avoid braiding or
twisting the foliage-that can hinder food manufacture and
means you need a hobby!
When planting your bulbs, you
can dig individual holes for each bulb, but that can be a lot
of work in our rocky soils. It is often easier to dig up an
area, scatter your bulbs in, and then fill the soil back in. A
general rule of planting is to plant two to three times the
size of the bulb, deep in the ground. Small bulbs are planted
shallow, while big bulbs need a deeper hole. Choose a site
with good drainage-especially in the winter. Standing water
and bulbs is not a good combination.
Spring bulbs are
out there in abundance now. While you can always add to your
collection of daffodils or hyacinths, consider some of the
more unusual bulbs. Even within the old tried and true
daffodils, there are some unusual options. Not all daffodils
are yellow, some are white, some have orange or pink centers,
some are fragrant and some aren't. By careful consideration
you can have daffodils in bloom from late January through
April. Most daffodils are long lived, and provided they get
some sunlight following bloom, will re-bloom year after
year].
Tulips aren't quite as easy. Tulips are usually
one of the last of our spring blooming bulbs to flower. Warm
temperatures during bloom can cause the flower display to pass
quickly, and often the leaves are quick to follow. This
coupled with the fact that many of the new tulips produce many
daughter bulbs, making them share the energy, flowers in
subsequent years are often smaller. Many gardeners treat
tulips as annuals, planting new ones every year. If you don't
want annual planting, consider some of the species tulips or
earlier bloomers.
There has also been a resurgence of
the heirloom bulbs which tend to take more abuse than some of
their showier new siblings. Regardless of which flower you
choose, or how long they last, tulips are definitely the
showiest spring bloomer, and worth the effort.
Crocus
bulbs may not stop traffic because of their demure stature,
but they are the harbinger of spring, and a reliable performer
year after year-sometimes even too vigorous. Give crocus room
to spread, because they will multiply. Crocus bulbs are often
interplanted in lawn areas. They grow so early and are low
enough growing, that they can give your lawn an early blush of
flowers and their cycle is complete by the time you need to do
the first mowing.
Hyacinths are one of the most
fragrant spring bloomers with clusters of pink, purple or
white flowers. They also will rebloom with ease for many
years, but do require annual fertilization. Old-fashioned
snowdrops and snowflakes will give you beautiful bell shaped
white flowers in early spring, and will do well in a more
shady location. Wind anemones will pop up early in the fall
with lacy foliage, and bright colorful flowers. They aren't
going to be around for too many years but are an interesting
addition. Others to consider are the showy and large Crown
Fritillaria with its crown of orange flowers, or the showy
giant alliums, large lollipop-like flowers with a delicate
onion fragrance.
Experiment with bulbs, and you may
find some new favorites. Fall planting is easy-the hard part
is the wait.
Vines
If you need some fast solutions for some simple problems,
look to vines. Whether you need a living screen, or you want
to cover a trellis or arbor, or you need some temporary shade,
or you simply want to add some color to a stark wall, annual
vines have much to offer. They are among the most rewarding
plants in the garden, giving you a wonderful display in one
season, and taking up little room in the garden. And unlike
their perennial or evergreen counterparts, they won't need
pruning, and they won't become invasive.
Vines add a vertical dimension
to make small spaces seem larger, and they provide privacy and
cooling shade. Most annual vines won't cling to a brick or
wooden wall, like their more permanent counterparts, but you
can use such climbing aids such as wire fences or trellises to
support them.
Many of our annual vines are actually
old-fashioned plants. Most old home sites used vines which
clambered up the side of the house, or clothed a trellis in
foliage and flowers, or turned a sunny porch into a cool,
leafy retreat. Why not choose these carefree plants to soften
your landscape. They are easy to grow, use a minimum amount of
ground space, and are pest free all season long.
Annual
vines are easy to grow in flower beds, hanging baskets, window
boxes or trellised planters. They transform unattractive
areas, and provide a quick and inexpensive solution to many
landscape problems. By using annual vines you can vary the
plants you are using and your color scheme every
year.
While some annual vines will reseed themselves
every year, for others you have may want to save your own
seeds or buy new plants. Most of them are heat lovers and will
not kick in and grow until the soil and air temperature warms
up. Even though they may be slow to get started, they thrive
all summer long, right up until frost. And since they are
"annuals" they only last one season.
There are numerous annual vines to
consider. Many nurseries now offer not only the seed, but
small plants as well. Check your local garden center or
nursery to see what is available. Cypress vine and cardinal
vine are closely related members of the morning glory
family. They both have outstanding crimson flowers which are
attractive to hummingbirds. The cypress vine is Ipomoea
quamoclit and has very delicate fern like foliage. It can grow
ten feet or more in height and has delicate star shaped
blossoms. It does best in full sun to partial shade. Cardinal
vine, Ipomoea x multifida has a slightly larger, more funnel
shaped flower, almost like a miniature morning glory but in
bright red, it has a wider leaf blade than the cypress vine.
It will also grow at least 10 feet tall. It does best in full
sun.
Don't overlook the common morning glory, Ipomoea
purpurea. While it may be a weed in some fields, there are
numerous varieties and colors to choose from, and they have
extremely showy flowers. Colors include the true blues, pinks,
whites, lavenders and magenta, as well as two tone flowers.
They have large heart shaped foliage and the flower size can
vary from as small as two inches up to 5 inches. Full sun to
partial shade is best, with this vigorous vine. Some varieties
may reseed freely, so learn to recognize it. It is considered
one of the most reliable bloomers, unless the soil it too
rich.
Another member of the morning glory family that
has become a popular vine is the moonflower, Ipomoea alba.
Unlike other morning glories which open early in the day and
are often closed by evenings, moonflowers don't begin their
show until evening. As if to emulate the summer moon, these
six inch white flowers open every evening at sunset. Not only
are they beautiful flowers, but they are fragrant to boot. If
you can find a plant, buy it. They can still be started from
seed now, but it takes at least twelve weeks or more for the
plants to begin blooming. Full sun to partial
shade.
And don't forget the ornamental sweet potato
vines, which are also in the morning glory family,
Ipomoea batatas. While they are a true sweet potato, they are
grown for their attractive foliage rather than their
production ability. While they can produce a tuberous root
that is edible, it is not highly rated, and rarely eaten. From
the dark purple 'Blackie' variety to the chartreuse leafed
variety 'Margarete' and a newer variegated foliage plant
called 'Tricolor', these vines rarely, if ever flower, but
they produce copious amounts of leaves which can spread up to
12 feet or more. These ornamental types were discovered in
the Philippines in the early 1980's.
And lest you think
all annual vines are morning glories, there are some other
highly prized plants. Hyacinth bean is an old-fashioned vine,
making a big comeback. Hyacinth bean, Dolichos lablab, is a
fast growing member of the pea family with large purplish
tinted leaves with dark purple stems. If this weren't
attractive enough, by mid-summer it is covered in deep
lavender pea-like flowers. These long lasting blooms, are then
transformed into glossy purple four inch seedpods, which are
every bit as pretty as the blooms. It will grow up to 15 feet
in a season. Uncooked beans and flowers are poisonous. Full
sun to partial shade.
Two other members of the bean
family are the runner beans: scarlet runner and Jack and the
Beanstalk. The Scarlet runner bean, Phaseolus coccineus
produces large vines with attractive scarlet flowers that also
attract hummingbirds. You can eat the flowers, pods and seeds
of this versatile bean. Jack and the Beanstalk, Phaseolus
multiflorus is another edible runner bean. This prolific vine
can grow 20 feet or more and has beautiful white flowers
followed by edible beans. If you want to have a utilitarian
vine, you can also grow gourds. From luffa's to the bottle
gourds, many of these make large vines with showy yellow or
white flowers, followed by the hanging gourds
themselves.
Another old-fashioned annual vine is the
black-eyed Susan vine or clock vine, Thunbergia alata. Flowers
may be orange, yellow or white, with or without a black center
or "eye". The common name clock vine comes from the fact that
the vine will twist around its support in a clockwise motion.
These vines can be grown in a hanging basket, or it can climb
a trellis, six to eight feet in a season. Partial shade is
best, and this is not a drought tolerant plant, so be prepared
to water.
Hops, Humulus lupulus, is another fast
growing vine that is legendary for its inclusion in beer
brewing. It is grown more often for its ability to quickly
cover a trellis or arbor and provide summer shade. It has sand
paper like leaves and aggressive tendrils that twine at will.
A herbaceous plant, it dies to the ground in the winter, and
may return in late spring to sprint upward its 15 to 30 feet
summertime growth. After it dies back, getting it off an
intricate structure can be tricky, so keep it your staking or
trellising simple. By the way, it is the flowers that are used
in beer. Actually it is the bracts and while both male and
female Hops make flowers, only the ripened cones of the
females are used to brew.
There are other annuals vines
on the market. Asarina, commonly called creeping
gloxinia, is a member of the snapdragon family. This vine is native
to Mexico where it reaches great heights. It should grow at
least ten feet tall, and blooms best in the sun. Flower color
varies from shades of pink to purple. Cobaea scandens, or the
Cup and Saucer Vine produces interesting flowers that start
out as green papery buds and open to reveal the green saucer
and bell-shaped flowers. They start off white, changing to
deep purple before falling off. This sun-lover can grow twenty
feet or more.
There are a few newer plant introductions
that are actually tropical plants, that can serve as summer
annuals. Mandevilla, the fast growing pink flowering vine,
blooms its heart out all summer long with flowers ranging in
shades of white to light pink to a dark hot pink. Allemande is
a yellow flowered vining plant. There are also several
clereodendron's that will spread some and give you outstanding
color all summer long.
Whatever the intended use or
location, there's an annual vine to suit your situation. For
most, it is plant them now, then stand back and let them
grow.
