Is it true that there are some hybrids that can't be bred with themselves to create more? Eg pink rose + pink rose will never make another pink rose?
If so, could someone please tell me which flowers this applies to? Thank you in advance
Almost all hybrids can be cross-bred with themselves to create more of the same hybrid including pink roses (although from my experience breeding pink roses are more likely to create non-hybrid flowers than other hybrids). The only exception is gold roses.
