All of the Astragalus are super tricky in humid Eastern climates. During wet times of the year, plants could easily rot, and the muggy nights of a hot Summer can easily ruin the gray foliage of some species. On the other hand, they can also shrivel and dryout during drought, so watering is a real issue. Need some sort of protection from excess winter wet, which also could easily kill them. Can be grown from seed, which doesn't always germinate! A challenge to say the least!
