We have a row of about 20 Ailanthus altissima trees growing in the back of our yard along the fence line and it's been there for at least 10 years. Edibles (annuals & perennials) that survive nearby include:
1. Prunus species (peaches, nectarines, etc)
2. Rubus species (rasberries, roses, etc)
3. Grapevines
4. Brassicas (during the dormant winter period but I think the allelopathic properties of AA will still remain in the soil)
5. Rosemary
6. Schinus molle (pink peppercorn tree)
7. Opuntia ficus indica
8. Mytillocactus
9. Sow thistle
10. Hook weed (cleavers)
11. Chickweed
12. Figs
13. Chinese elm tree (seeds are leaves are edible though not very palatable)
Hope that helps!
