Passionfruit also will go up a tree or cover a garage and purple eggs tastier than peaches fall roll off and fall on the ground. Their purple fruit is at every market these days. The ripe, yellow tomatillos and tomatos yield seeds. Possible Lists are longer than my memory. I just found tamarind pods at my Super.
Seeds are like agate or rubies.
In 8 years I'll have pod-bearing trees for candy and soft drinks. If you need information on any of the above. Go to small, private nurseries to ask questions. Also,the internet has boards, chat groups, websites. Always volunteer to trade plants for info.
