outcropping and stood out with its
distinctive silvery foliage amidst the
plentiful and typical green-to-grayish
leaved forms of Viola walteri in the
population. After its discovery, the
plant spent seven years at Mt. Cuba
Center as it was propagated (asexually)
and planted out in the gardens.
A key vision of Mt. Cuba Center -
imparted to them in no small way
by the late Mrs. Lammot duPont
Copeland - is to promote a
broader availability of high-quality,
improved plants for the greater
gardening community by evaluating
and introducing plants which can be
successfully nursery propagated, while
combining robust ornamental appeal
and broad regional adaptability.
The partnership between Mt. Cuba
and North Creek is a friendship that
runs deep and spans decades. When
the decision to share 'Silver Gem' with
the nursery industry was made back
in 2010, the decision as to who to
contact was easy.
The following year in 2011, 161 flats
were sold at North Creek, immediately
engaging industry interest. North
Creek was able to produce new plants
from our own stock for about seven
years. Over time, although industry
interest expanded, stock plants had
grown weaker and less capable of
rooting successfully. By late 2019,
a need for change was recognized,
and the decision was made to switch
production methods from stock plants
to tissue culture.
After initiation, the tissue culture
lab worked to refine their production
methods, and North Creek collaborated
with them to navigate the timing and
quantities of shipments of inputs.
Today, numbers are expanding, and
inputs are looking better than ever!
" We are also experimenting with
augmented windows of availability, "
Courtney Knight, North Creek
production administrator, said. " 'Silver
Gem' thrives in cooler conditions, so
we began offering it with midwinter
potting in mind. However, with more
demand and better input availability,
we are excited to also offer larger
quantities of plants for fall and spring
planting windows, as well. "
Please reference our website for
current offerings and projected future
dates of 'Silver Gem', we hope you
find joy in the growing and gardenworthy
nature of this gem!
