A member of Section Calcarifera, D. cerinum flowers in hanging rispes from the leafless canes during dormancy. No scent for me, but the 3cm flowers last well, about 3 weeks and are a joy in Winter. Plant is an intermediate to warm grower, profiting from a cooler rest, about 40cm-50cm tall, should be kept moist and in good light, but doesn't require massive sun. Easy on the windowsill or in the conservatory.
