Take avocados off your list. They are very thirsty! High maintenance. According to an article I read on yahoo this morning, due to California's drought and the costs of keeping them alive and healthy, Avocados are the next caviar! We have 3, and they do require a lot of water. Most plants require water while getting established. Prickly Pear might be your best bet. I have one fig tree that wilts in the heat. Violette De Bordeaux. Panachee Fig turns yellow and drops her leaves if her emitter is clogged and she doesn't get the water she loves. We named one of the paths that meander through our acreage "Olive Lane," because we planted two Olive trees to flank it. They both are on the drip system. One tree is thriving. The other is stunted. Both very green. For a year one had no water and the other did. We didn't notice the broken emitter. A drought tolerant vegetable tree is Moringa Oliefera. We grow that as a hedge and use the leaves in salads. I'm not a fan of the pods, but the trees buzz with bees after the flowers.

Hi, I'm in the same boat. I haven't been able to find any of those. A member of the citrus forum pointed out that Four Winds Growers does have Australian Finger Lime: https://ssl4.westserver.net/fourwindsgrowers.com/secure/consumer/ Sid

Has anyone ever done work with the Australian desert lime . What crossbreeds are possible ? What has been done ?

So I checked my tree yesterday and it has exploded into bloom!! The weird thing is the flowers have anywhere from 3 to 7 petals on them!! Had to enlist help from my husband to take this picture for you :)
