I have tomatoes-many varieties, bell and jalapeño peppers, eggplant(many varieties), pumpkins, squash, beans, carrots, lettuce(many varieties) and more. All of these seeds are organic and were purchased this year Brent

Where are you located Annamaria? This will dictate everything. If you are in a mild climate, you won't want to bother with one of the wild species, but should definitely get a cultivar of Opuntia ficus-indica. These should be readily available from warm-climate nurseries. If you're in a colder zone, you could try Opuntia engelmannii or related wild types. Many of these are available through mail order nurseries specializing in cacti and succulents as well as unusual edibles. I see that Edible Landscaping sells one that is hardy to zone 7. Of course, anywhere in the arid but not-too-cold western part of the country you are likely to see some growing wild or as part of landscaping. Just collect some pads from a variety of plants and wait a year or two to taste the fruit!

first let them dry well!What i do is plant them in a peat-perlite mix (lots of perlite!) and give them warmth;they are quick to germinate and if conditions are right youll have miniature prickly pears in about 3 months!(when i say miniature i mean finger-sized! lol)i dont use sand coz where i plant them is their permanent spot and my medium must have some nutritients! I have no idea about strelitzia care though! cheers

Though I believe all of them have edible fruit only certain ones have tasty fruit. Most of the 'tuna' or prickly pear fruit you buy in the ethnic grocery stores comes from the large tropical cactus which won't overwinter here in NC. I think it is most often called West Indian Fig but it has a lot of names. Oddly, some of the tastiest ones are not always purple or red, they can be any shade of green with a blush of color towards the top. The taste is kinda sour/sweet with an odd metallic tang that some people do not like. They make good jelly but you have to be careful because the juice will stain everything (hands, clothing, cookware...etc.)
