PRIMO ® offers a fresh look at the Heuchera line up from Proven Winners ® . Vigorous plants with large foliage and long lasting
blooms are show stoppers in the landscape and a must have this Spring. The varieties in the PRIMO ® series were selected for
their unique foliage color and outstanding flower color.
PRIMO ® Black Pearl Heuchera
In our opinion, the best black Heuchera yet! Forms an
incredibly dense clump of jet black, shiny foliage that you
need to touch to see if it’s real. Scalloped edges give this a
more unique and polished look than typical Coral Bells. White
flowers with pink calyxes in mid-Summer on 18-20" scapes
(requires vernalization).
PRIMO ® Mahogany Monster Heuchera
The name says it all! Massive, glossy, mahogany-red leaves form
a substantial clump of foliage.
PRIMO ® Peachberry Ice Heuchera
A beautiful option for adding orange to your shade garden.
Large, apricot-orange leaves have a silver overlay, beautifully
pronounced ruffling, and bright pink undersides.
PRIMO ® Pretty Pistachio Heuchera
A great perennial prized for its flowering and garden
performance alike. A big and beautiful plant: chartreuse leaves
mellow to lime-green in Summer. Huge, medium-pink flowers
rebloom from mid-Summer until frost on 20-24" scapes.
PRIMO ® Wild Rose Heuchera
PRIMO ® Wild Rose Heuchera forms a dense habit of large,
bright, rosy-purple leaves with deep-charcoal-gray veining.
The prominent, dark veining really causes the foliage color
to pop, making it a great choice for shade. This is the perfect
companion plant to the dark-leafed ‘Black Pearl’. Upright, dark
burgundy-rose flower scapes have matching dark buds that
open to rosy-pink flowers.

GROWING TIPS
» Provide light shade to keep plants from scorching.
» Botrytis can be a problem under cold, wet, low light conditions.
» Use cool temperatures to hold plants once they reach the size desired.
» Avoid overly wet conditions as it may lead to crown and root rot or a poorly performing
plant. Allow plants to dry slightly between irrigation cycles.
» Needs 75 – 100 ppm N per irrigation.
