Daphne x rollsdorfii ‘Wilhelm Schacht’ (ex: John Bieber) – 'Wilhelm Schacht' is a D. collina and D. petraea cross. The buds are a deep purple shade opening rich pink-purple from which sweet perfume wafts. If happy ‘Wilhelm Schacht’ may possibly rebloom later in the season. This shrub with bushy habit is composed of dark evergreen glossy foliage. This beauty is evergreen for us in northeastern Connecticut through relatively mild winters. It has performed well for us in USDA zone 5b set in full sun near a small boulder in our xeric garden. We have been “wowed” by the bud count, flower color and its delicious scent.

Daphnes are shrubby members of Thymelaeaceae. Many have thrived in our xeric garden which provides a deep root run, good drainage with no extra water during droughts. We add dolomitic limestone to the planting holes when initially interring them. Most have fragrance which is heavenly, perfuming the air near where they bloom. We have observed those that flower or rebloom in summer draw hummingbirds.
For all the discussion about their finicky personalities we have found them mostly quite easy to please in the ground though they, as a group, are largely not happy in containers for long; in containers death visits frequently - especially the yearlings - and it is as annoying as frustrating! As my good friend, Jonathan Lehrer, has told me on occasion, “Daphnes will never be a mainstream shrub because even the easy ones will up and die suddenly for no apparent reason.” My feeling is nothing goes on living forever; for all of their remarkable qualities they are worth growing for as long as they choose to be around! Certainly, the hybrids (x burkwoodii and x transatlantica) exhibit exceptional hybrid vigor, strength and ease of establishment.
Snow loads in the north can be an issue on taller growers, therefore, I suggest pruning older plants after flowering to ensure stouter, bushier shrubs that may better counteract weighty winter precipitation. After pruning they recover beautifully and quickly. Also, all that flower in summer are attractive to hummingbirds. Most of our selections come to us gratis from John Bieber who lives on Long Island, longtime lover of all things Daphne. Most of our Daphnes are cutting grown. There are exceptions including D. alpina which has been completely resistant from stem cuttings; these will be seed grown when we do have them available which may be infrequently!
