I am not sure the growing information that this plant has high water needs is accurate in all cases, as the one in my yard volunteered between the sidewalk and the grass and was not watered except for rain (which my area is already 6" behind in rainfall (typical annual rainfall should be ~ 32") this year and it's only April). It only got saved from the mower, as I could see the delicate foliage was quite distinct from the grass and the plant was taller and putting on buds, so I decided to wait & see what it was when it bloomed. It was worth the wait. I will try to collect seeds and plant them so I have more next year.

Caution:
All parts of the plants of the genus Delphinium contain poisons and should never be eaten. Humans and animals can be fatally poisoned by their consumption. Children are most vulnerable because of their small size and natural curiosity. Toxicity varies according to season and the plants' parts and stages of growth. In addition, the plants absorb toxic entities, such as pollutants, pesticides and herbicides from air, water and soil.

A beautiful, easy wildflower for your meadow planting. Self-sows and can be a bit invasive in my Austin garden. I used to fight it, but I decided instead to enjoy the maintenance-free spring blooms.
