I have a dim memory from childhood that bulbs, particularly hyacinth bulbs, can be grafted together. If it really IS possible you’d have thought there would be more about grafting bulbs online… alas, a search turns up very little.
Cut two different colour hyacinth bulbs in half
Join them together
Tape them up
Plant them and wait
The only reference to grafting hyacinth bulbs that I can find online comes, surprisingly, from Charles Darwin’s book Animals and Plants Under Domestication:
“I should not have quoted the following case had not the author of ‘Des Jacinthes’114 impressed me with the belief not only of his extensive knowledge, but of his truthfulness: he says that bulbs of blue and red hyacinths may be cut in two, and that they will grow together and throw up a united stem (and this I have myself seen), with flowers of the two colours on the opposite sides. But the remarkable point is, that flowers are sometimes produced with the two colours blended together, which makes the case closely analogous with that of the blended colours of the grapes on the united vine-branches”
We will keep our fingers crossed here at Sheepskin Towers, hoping for some growth and perhaps even some multi-coloured flowers… I’ll post an update in due course!
