It's that time
again--time for the Adams Co. Master
Gardeners to plant their Trial Garden
and care for it all summer long as the
plants grow and get more beautiful. I am
always amazed at the number and variety
of new plants that are developed each
year. When I get the list of the Trial
Garden Plants that are made available
from Penn State every spring I usually
go to the Internet to find pictures and
descriptions of those annuals. This year
I searched in vain for several plants:
Begonia Bayou series, Calibrachoa
'Callie Sunset,' and Verbena 'Moon
River.' Possibly these are not new
varieties, but they are new to me and, I
suspect, to many people. The reasons for
developing new varieties are many: more
disease resistant, different (and
better) colors, more adaptable to a
particular area, and the challenge of
something new.
The Master
Gardeners are responsible for planting,
caring for, and evaluating the annuals
we receive from Penn State. It doesn't
even seem like work when we can observe
the progress the plants make. We want to
share all this fun with other flower
lovers and gardeners.
Some plants are
not new but are available for the first
time to our Trial Gardens. Torenia
'Summer Wave Blue' is on the list for
the first time. Torenia is easy to
grow--a great choice for beginners. They
can be planted in beds or containers and
have "snapdragon"-like flowers that are
produced in abundance all season--right
up to the first frost. Torenia is heat
tolerant and is cold hardy to 35
degrees. Plants should be spaced 8 to 10
inches apart in beds. Soil should be
kept moist but never soggy. Fertilizer
should be applied every month as a
balanced liquid fertilizer, or feed
container plants every two weeks.
Torenia (also known as wishbone flower)
may not do so well in the Adams Co.
Master Garden Trial Garden because it
likes partial shade. Our garden is in
complete sun so we shall see how it
does. It may be susceptible to powdery
mildew.
Bacopa is a
new-to-our-garden annual that is usually
grown in containers and is excellent for
trailing over the edge of mixed patio
pots or hanging baskets. We will be
growing it in the ground so it will be
interesting to see the results. It
prefers a cool, semi-shaded location and
flowers in late spring to summer. Since
Penn State provides plants to Master
Gardener Trial Gardens across all of
Pennsylvania the growing conditions can
be quite different. The goal is to
provide plants that will succeed in many
different environments.
Another plant
available to us this year is Agastache
'Golden Jubilee.' This was an AAS award
winner in 2003. It has golden leaves
with dense spikes of lavender-blue
florets that crown the plant from mid to
late summer. It is considered an herb
with an alluring mint fragrance and will
probably return in following years. It
should get 20 inches high and will
spread 10 to 15 inches. It thrives in a
full-sun garden or a partial-shade
location.
Hollyhock 'Queeny
Purple' is new to us and the plant
world. It is the shortest of the
hollyhocks and also has won an AAS
award. The flowers are a beautiful
purple with frilly edges of the
powder-puff type with a cushion center.
The plant will reach a mature height of
20 to 30 inches, perfect for smaller
space gardens. You will soon be seeing 'Queeny
Purple' available in garden centers.
Phlox 'Intensia
Neon Pink' is a vigorous spreading
plant. The flowers are one inch and
completely cover the plants. Intensia
has unique new genetics and will look
great in hanging baskets, pots, larger
combination containers and the
landscape. Spacing should be 10 to 12
inches. These plants will be perennial
in the south but so far a zone has not
been established. They should be in
moist but not wet, well-drained soil.
Feed twice a month in beds and every
week in containers.
A plant that is
returning to our garden is Argyranthemum
'Butterfly.' I hope it will be 'Vanilla
Butterfly.' The flowers range in color
from soft cream to pure white. The
previous argyranthemum in the Trial
Garden was yellow. These plants all have
large flowers, vigorous growing habit
and excellent heat-tolerance. It will
probably flower all summer in hot
climates . It can take full sun or
partial shade and combines well in
containers or in the landscape.
Deadheading will improve its appearance.
Celosia has been
a popular plant in our garden. This year
we will be getting Fresh Look Red and
Fresh Look Yellow. Both these celosias
will do well in hot, humid weather,
thriving in drought or rainy conditions.
They need minimal maintenance, always
look fresh with no grooming needed. Both
plants will grow to 12 to 18 inches and
spread 12 to 20 inches. To do the plants
justice, they should be mass planted (at
least nine to fifteen plants to a drift)
for an effective landscape display. And
don't forget to dry them for winter.
They should be harvested before they set
seed. Then strip foliage and hang upside
down in a cool, dark, well-ventilated
area.
Some plants will
be returning again because they were
successful enough to repeat. Cleome
'Sparkler Mix' is one of our returning
plants. If you are familiar with cleome
this one will surprise you. It is
shorter and branches prolifically to
provide many more flowers at the ends of
the branches than the old-fashioned
variety although maximum height can be
as much as 48 inches. This variety can
be planted close enough to use as an
annual hedge or be planted at the rear
of a bed. Cleome is very heat and sun
tolerant and it reseeds vigorously.
Unless you want a hedge, plant the new
plants 24 to 30 inches apart. The
flowers are good for cutting.
If you've been
visiting our Trial Garden throughout the
past 5 or 6 years you will be amazed
that this year we will have only one
petunia--Petunia 'Tidal Wave Silver.'
The Tidal Wave series has a unique
growth habit. The closer together the
plants are spaced, the taller they get,
anywhere from 16 to 22 inches in height.
Or if they are given a trellis to climb
on, they can reach 36 inches. They also
make an excellent ground cover. They do
not need deadheading and recover quickly
from rains. Space plants 12 to 36 inches
apart, depending on how quickly you want
the area to fill in. Feed monthly with a
liquid fertilizer.
By now you have
probably seen (and been impressed with)
Ornamental Millet Purple Majesty Hybrid.
It grew in our garden last summer and is
eye catching. It is deep purple from the
base of its stem to the tip of its long,
flower-packed stalk. It can grow 4 to 5
feet tall with flower stalks a full 12
to 14 inches long all summer. In fall
the stalks will turn to shiny purple
seeds for the birds. It thrives in high
heat and sun; grow it alongside the hot
driveway, in the foundation border,
along a fence, or near a warm wall.
Space plants about 10 to 12 inches apart
for a hedge effect. It can also be grown
in containers with other plants and will
make an impressive arrangement.
I'll end this
list with my favorite--Rudbeckia
'Prairie Sun.' This robust rudbeckia has
distinctive blooms with a light green
central cone which blends beautifully
with the golden yellow petals which are
tipped with primrose yellow. Five inch
blooms on branching plants that mature
at about 3 feet tall make a strong
statement in any full-sun garden. They
are easy to grow and maintain. 'Prairie
Sun' is a memorable plant in any
perennial, annual, or cut-flower garden.
The flower stems are sufficiently long
for quality cut flowers.
We will be
receiving our plants in May; we are
planning on a planting date of Tuesday,
May 25. The Master Gardeners have
already prepared the beds by rototilling,
fertilizing, edging and generally
improving the beds for this year's
garden. You, the public, are invited to
watch us plant on the 25th in the
evening, starting at 6 p.m. Come and
observe, ask questions, make
observations, and just enjoy our
enthusiasm for our newly planted garden.
Then throughout the summer stop by when
you are in the area to see the progress
of the plants.
Guided Trial
Garden Walks are planned for the
following Wednesday evenings all at
6:30: June 16, July 7 and 21, Aug. 4 and
18, and Sept. 1 and 15. A Master
Gardener will be present to tell you how
the plants are doing--whether they are
meeting our expectations and fulfilling
their descriptions.
Besides the
Trial Garden, there will be Native
Garden walks, also on Wednesday evenings
at 6:30: May 19, June 9 and 23, July 14
and 28, August 11 and 25, and Sept. 8.
They will also be led by a Master
Gardener and you will learn about some
of the special natives we have planted
to surround the Ag. Building.
One more event
is planned to feature our gardens. The
Master Gardeners will be holding a
Garden Fest on June 12 from 9 to 3. This
will include workshops, garden walks,
compost information and events for
children plus vendors and a food vendor.
Come and spend the day and bring the
family. For a brochure or more
information, call 334-6271.
