What is proliferation?
Proliferation is a disorder that usually affects the flowers of a range of plants including clovers, the daisy family, opium poppies, plantains and roses. Bellis perennis ‘Prolifera’ – the hen and chickens daisy – is a stable cultivar that exhibits the phenomenon reliably with flowers arising from within the main flower. Occassionally a triple-tiered effect with flowering arising in the second set is seen.
The opium poppy ‘Hens and Chickens’ is an example of where secondary flowers are formed around the main flower.
Another type of proliferation is occasionally seen in plants with solitary flowers. Certain roses seem particularly prone, with the flower stalk appearing to grow through the flower to produce another flower, creating a two-tiered effect .
