Are there any pear trees that have purple or red foliage year-round and that are also good for fresh eating?
Does new red foliage before turning green count? Several do that including red bartlett. For example, once the foliage has turned green, it’s noticeably replaced by brilliant red or purple fruit so you continue to see color.
Ooharabeni is an asian pear which keeps dark red/purple leaves for a time and eventually turn green. I don’t have much experience with that or know if it’s worthwhile.
