| Do some googling using 'interspecific cross' and 'intergeneric cross' (or something similar) to obtain some information. This sort of natural and human-made manipulation is well documented in agriculture, floriculture, agronomy, horticulture, and many other fields. One of the more famous ones in ornamental use is, of course, X Fatshedera lizei, a cross between Fatsia japonica and Hedera Helix. After all, if it happens in the animal kingdom, why not plants? |
