plant reproduction
To start nitpicking: not all Rosacaeae are guaranteed to have perfect
flowers. It is the rule but exceptions can be found. My local flora states that Sanguisorba can have 'male' flowers only PvR Monique Reed schreef That's not a case of unisexual flowers, though, not in the Rosaceae. It's self-incompatibility. With things in this family (notably cherries), often one cultivar is incompatible with itself and needs a different cultivar. You can get around this sometimes by grafting on a branch or two of a different cultivar. M. Reed P van Rijckevorsel writes Isn't there any number of fruit trees who need to have a 'male' planted somewhere near them for them to bear fruit? Maybe I can think of them when feeling a little less woozy. PvR Stewart Robert Hinsley wrote: Apples for a start, though I wouldn't swear that it applies to all cultivars.
