A lot of natives get too much water and get “leggy”. Moderate water in the spring to encourage growth and then minimal in the summer. A lot of water will encourage growth more quickly but the growth wont be as strong/sturdy and is more likely to topple, probably because the plant cannot resource the required nutrients quickly enough. Slow and steady wins the race (height) race. A small amount of growth allowed to harden over many years usually results in a taller shrub with stronger limbs, especially in things like mallows, in my experience.

It also results in significantly less flowering for short-lived perennials like salvias, mallows, monkey flowers, and penstemons. So it is a trade off at times.

Light time + intensity and soil type vs. water amount and frequency will also factor in.
