i'm gonna guess there aren't too many references here for carambolas because they only grow in south florida- like other tropical plants. are you in south florida? my mom grew one for quite a while- till they moved out. it was awesome to have your own tropical carambola tree with fruits! if i remember correctly though they were on the small side- not like those huge things i've seen at the grocery! she tried papayas too and we had a frangipani growing right outside the front window too. ahhhh------ i sort of miss those tropical plants.....
