SPRING PERENNIAL GARDENING
Spring is the time when Mother Nature gives us her most beautiful
and intense shows of flowers. When these displays of flowers are
seen, often time we desire to have our yards look the same. There
are many the types of flowers that can be planted in our gardens
and yards that are low maintenance and beautiful.
One item of note is although springtime is when many flowers bloom,
it is still desirable to plant summer and fall blooming perennials
so that there will be flower color in the yard throughout the entire
growing season.
BULBS
Although bulbs are a part of the spring garden they
must be planted in fall. Here are a few of the more common types.
CROCUS: Crocuses are usually the first bulbs to bloom. Often
times they will come up through the snow. These flowers are usually
less than 6 inches tall and come in a variety of colors from white
to yellow to purple. Crocuses look best planted in clusters of 10
to 25, and plant at a depth of around four inches.
DAFFODILS: Daffodils and their relatives Jonquils are usually
yellow, but sometimes are cream colored or white. Blooming in early,
mid and late spring, depending on the variety, bulbs look good in
flowerbeds, rock gardens and in woodland settings. Daffodils are
very low maintenance, but need periodic dividing to keep them vigorous.
Plant them to a depth of six inches in sun to partial shade. One
cousin of the Daffodil, Paperwhites, is not cold hardy in the northern
Utah climate.
HYACINTHS: Hyacinths have been grown in western gardens since
the eighteenth century. They will bloom in early spring and come
in colors including white, pink, salmon, blue and purple. These
bulbs were traditionally used in more formal gardens, but look great
used in other settings. Plant them at a depth of six inches. Hyacinth
flowers may become leggy after a number of years, and it is desirable
to periodically replant them every few years.
TULIPS: Tulips are the most popular bulbs in Northern Utah.
The reason for this is that they come in almost every color of the
rainbow, they vary in size from three or four inches tall to over
a foot tall, and there are different varieties that bloom from very
early spring to late spring. Depending on the eventual size of the
Tulip plant, plant them at a depth of four to eight inches. It is
important that tulips get as much sun as possible so that they will
have good flowers the next year. A group of tulips, called Darwin
Hybrids, are among the easiest to get to re-bloom year after year.
SPRING BLOOMING PERENNIALS
Spring blooming perennials can be planted at anytime of the growing
season, although spring is usually when the best selection is available
in the nursery industry. It is worth planting spring blooming perennials
throughout the summer and fall to get them a head start for their
flower displays in the spring. The following list of perennials
includes plants that are more commonly planted in the home landscape,
but is in no way a complete list of what is available. There are
literally hundreds of perennials that have attractive spring flower
displays.
BASKET OF GOLD: Basket of Gold, also known as Alyssum, is
unique in that it offers a mass of yellow flowers in early spring
when almost no other plants will do this at this time of year. It
flowers at the same time as Spring Phlox, and Candytuft. Alyssum
has a weeping habit that works well in rock gardens. Basket of Gold
will flower profusely for three or four years but will probably
fade after that, so replanting is sometimes necessary to maintain
vigorous flowering. One other factor that should be taken into consideration
is Alyssum foliage is not the most attractive after it is done blooming.
Plant it in places that other plants and flowers can hide it later
in the year.
BLEEDING HEART: Bleeding Heart has been a popular spring
perennial for a many years, and many people remember seeing it in
Grandma's flower garden. Bleeding heart has the advantage of being
one of the few perennials that will flower in the shade. In fact,
it must be planted in the shade for it to thrive. Flower color ranges
from white to red. Bleeding Hearts can reach a size of two to three
feet high and wide, and there are also dwarf fern-leaf varieties
available that will only reach a maximum height of 18 inches. Bleeding
Hearts will naturally die back in late June or early July, but have
no fear; they will be back the next spring.
CANDYTUFT: Candytuft is an awesome perennial. It has white
flowers in early spring at the same time as bulbs, Phlox, Basket
of Gold, and Rock Cress. After it is done blooming it still has
nice evergreen foliage that will add interest to the flower garden.
Candytuft has a weeping habit that naturally lends itself to rock
gardens, but it also works well anywhere else as long as the location
has good sun. Severely cut back Candytuft every other year to keep
the plant vigorous.
COLUMBINE: Columbine is one of the most popular spring flowers.
Flower colors will range anywhere form yellow, lavender, white,
and purple. Columbine looks good in rock gardens, woodland and other
naturalized settings, and it will reach a size of two feet high
and wide. Cut back dead flower heads and then cut the foliage back
as it turns yellow in late summer.
CREEPING PHLOX: The Phlox family is a large family whose
members are all North American natives. This is the purple or pink
flower that is seen in mass in early spring. Phlox come in colors
from white to pink and purple, and is nice planted in mass in rock
gardens and other flowerbeds. They are also sometimes used as groundcovers.
Phlox is best planted in the fall but also does well when planted
in spring. Phlox does best in a well-drained soil and is sometimes
susceptible to spider mites.
DIANTHUS: The Dianthus family includes many popular flowers.
Some of the more common varieties include: Carnations, Sweet Williams,
and Pinks. Most Dianthus will start blooming in late spring or early
summer. If the dead flower heads are cut back they will bloom for
much longer. Dianthus either grows in large clumps or as a groundcover,
and it will grow six inches to a foot high. Some of the better varieties
to plant are: Sweet Williams, Raspberry and Strawberry Parfait,
Zing series, Telstar series, and Cheddar Pinks. Some Dianthus is
short lived so periodic replanting may be necessary.
FOXGLOVE: Foxglove is a very interesting plant. Not only are
they beautiful, but they have been used medicinally for over three
hundred years. A drug called Digitalin is taken from the leaves
and used to treat heart ailments. Do not try to cure your own heart
problems with it because of the powerful nature of Digitalin. Foxglove
is biennial or a short lived perennial. It will reach a height of
two to three feet when in flower; because of this it is a good background
plant that will create height in the flower garden. Foxglove does
best in partial shade, and it also likes a moist but not an excessively
wet soil. It comes in colors of white, red, and purple.
LUPINE: Lupines are probably best known as a mountain flower.
In the spring they bloom at the same time as many other alpine perennials
such as Columbine and Phlox. The types of Lupines that are most
commonly grown in the home garden are the Russell hybrids. They
are the easiest type of Lupines to grow, coming in a variety of
colors, and thriving in full sun to partial shade. Lupines are biennials
or short -lived perennials.
PERENNIAL GERANIUM (CRANESBILL): Perennial Geraniums are
another native wildflower that will grow well in the home garden.
They flower profusely in mid-spring in colors of pink, white and
purple. There are many varieties available, but Johnson's Blue is
one of the most popular. Most Geraniums will grow to 18 inches tall
and will spread a couple of feet. Cut back Cranesbill after it has
flowered and it will sporadically flower through the summer. It
is also possible to divide Geraniums in the fall every three to
four yeas.
ROCK-CRESS: Rock-Cress is a good border plant and also works
well in rock gardens. Not only does it have nice flowers but has
visually pleasing foliage so it will look good all season long.
Rock-Cress has white flowers in early to mid-spring and works well
when planted along with Phlox, Basket of Gold, and various bulbs.
It will reach a height of only six to 10 inches, and so it should
be planted in areas where it is more visible. Rock-Cress can be
easily divided every couple of years.
