I was wondering, I have heard that both of these varieties prefer not really being pruned and that they create these beautiful, mounding, arching bushes.

Does that mean they can be, generally speaking, completely ignored and allowed to grow, unchecked?

I have an unsightly hill behind my patio, and I was just thinking outloud that the arching, sprawling nature of both of their growth habits would look nice cascading down the hill. It's not completely inaccessible if it needed some rejuvenation pruning every few years, but can it get by with 0%?

I've also heard that both are pretty drought tolerant. Do you think, once established, they'd be OK without water? Or will they generally still need regular water and fertilizer to bloom?

Thanks!
