Karen, in my very dry area, yes, it will need a bit more watering, with the very low humidity. It is the thermal heat that is not good for it especially when we start hitting the high 90's to triple digit and very dry, leaves will start wrinkling bad and plants will just slow down, just too dry for it, even in shade. And my other enemy as already mentioned by others are the slugs. I grew mine in a container before, also experimenting then how the plant will behave here.
You may want to put several layers of mulch to help hold the moisture around the plant, and use a soaker hose if you are planting inground, and position in your shadiest side of the garden.
