Lenten
Rose Black Diamond belongs to the Winter Jewels™ Series. This helleborus has a
bold slate purple, almost near-black blossom, that measures 2-21/2 inches
across! The foliage emerges purple in the early spring and matures to a
beautiful shade of green.
It
flowers during the Christian Lenten season of Lent, from which it gets its
common name. This helleborus is a hardy, easy to growl perennial that thrives in
partially sunny to full shade location. This low maintenance plant is tolerant
of heat and humidity. It grows to a height of 15-18 inches and thrives in zones
4-9.
Lenten
roses can be slow to establish so give them a year or two to settle in before
flowering. Since it is shade tolerant, it can be planted under small,
low-spreading trees. The flowers can last more than 10 weeks because they bloom
during the cool season.
Lenten
Roses could use 3-6 hours of morning sun, and afternoon shade is best to keep
the foliage from withering. In the spring, add a couple inches of mulch or
compost around the base of each plant, which helps improve the soil and keeps
the roots cool and moist. When dividing is necessary, do it in August or early
September.
