Is aralia spinosa a suitable vegetable as well? I was picking the seeds but i have no experience with it other than an native ornamental
Aralias are all very different. Some are shrubs, like Aralia spinosa or Aralia elata. Some are gigantic herbs, like the spikenard group which includes udo and American spikenards. Others, like wild sarsaparilla (A. nudicaulis) are creeping subshrubs that look just like a low herbaceous layer except that they have little fingers poking up from the duff in winter. All of them are edible as far as I know, and Plants for a Future lists A. elata leaves as edible, but I’d recommend checking on the species for yourself before deciding to eat them.
