+ Laburnocytisus Adamii is a Graft Hybrid or Chimaera; produced by grafting Cytisus purpureus (a large bushy shrub with pinkish-purple flowers) onto Laburnum anagyroides (a smallish tree with yellow flowers).
The result is a plant that bears three different kinds of flowers; some that are wholly yellow and look just like the Laburnum, others that are purely pinkish-purple and look just like the Broom, and a third type that are bronze-coloured or mottled - apparently a mixture of the two.
My question (I have googled this, but I can’t find any in-depth info) is: What is actually going on in this plant at various different levels? - do both plants contribute equally to all structures (such as the vascular system etc)?
I presume that the cells of each parent plant remain entirely distinct and that, given sufficiently delicate techniques, tissue could be dissected out and micro-propagated into one or other of the pure parent species?
