Coseh 4100 Ice N' Roses Red Lenten Rose

Helleborus glandorfensis 'Coseh 4100'

The Story

Plant Bio

Hellebores are cherished, long-lived evergreen perennials that bloom in the cold months from late winter to early spring. They feature handsome, leathery, palmate foliage and cup-shaped flowers that are remarkably frost-resistant.

'Ice N' Roses Red' ('COSEH 4100') is a complex hybrid known for its exceptional vigor, heat tolerance, and large, outward-facing flowers. Its deep red blooms appear very early and hold their rich color for an extended period, making it a premier choice for winter gardens.

Uses & Benefits:

Ice N' Roses Red provides a rare and welcome splash of rich color in the late winter landscape when little else is in bloom. Its elegant, outward-facing flowers and handsome evergreen foliage bring life and sophistication to shady corners, woodland gardens, and entryways.

This is an incredibly tough and long-lived perennial that is resistant to deer and rabbits. The leathery evergreen leaves provide year-round groundcover, and the flowers are excellent for floating in a bowl of water indoors as a long-lasting decoration.

Hellebore flowers are a critical early-season food source for foraging bees and other pollinators emerging from winter dormancy. They provide vital nectar and pollen when few other resources are available.

How to Grow

Select a site with partial to full shade, especially from hot afternoon sun.
Amend heavy soil with compost to improve drainage and fertility.
Dig a hole twice as wide as the pot and just as deep.
Gently place the plant in the hole, keeping the crown at soil level.
Backfill with amended soil and water thoroughly.
Mulch with leaf mold or compost, keeping it away from the crown.

Pro Tip

Cut the old foliage to the ground in late winter to best display the emerging flowers and prevent leaf spot.

Keep It Thriving

Care Guide

Do

Plant in rich, well-drained, neutral to alkaline soil.
Provide consistent moisture, especially during dry spells.
Remove old leaves in late winter to prevent disease and showcase flowers.
Allow them to self-sow if you enjoy surprises (hybrids won't be true to type).

Don't

Do not plant in waterlogged or acidic soil.
Avoid deep planting; the crown should be at or just above the soil line.
Don't disturb them once established; they resent being moved.
Avoid heavy chemical fertilizers; an annual top-dressing of compost is sufficient.
