Hydrangea Quercifolia

Oakleaf Hydrangea Snow Queen

Snow Queen is as majestic as the name calls it!

You will find this hydrangea quercifolia interesting throughout the year - large, bold, deep green foliage turn deep, burnt red late fall. And the leaves stay throughout the winter until the new growth emerges! The white blooms are just as striking, held up high and strong, and fades into pink-red. Easy to please, it thrives in not so rich soil with very little attention.

Fragrant Companions

Daphne Odora

The sweet narcissus-like scent of Daphne Odora wafts in the air in the middle of the winter. Native to China, Korea, and Japan, the vigorous clusters of pink or white blooms on glossy, green or variegated, round edged foliage offer a sensory feast in winter when the ground is still too cold for many others. Plant where water naturally runs off or in well drained soil.

Sweet sunshine in bleak, dreary winter!

If you are not familiar with this unique, head-turning, intoxicating, winter-blooming Edgeworthia, welcome to the new world! Creamy yellow flower heads open up masse of bright yellow florets on the tip of the branches in February-March, and the blooms stay on almost 8 weeks releasing intensely sweet fragrance!
