Callirhoe involucrata requires full sun to maintain healthy growth and thrives in depleted, gritty, dry soils.  Too much moisture and shade tend to create rot and pest problems.  This plant develops a very long taproot, making it incredibly drought resistant, but also rather difficult to transplant, so choose its site carefully.  Mature plants spread out over about 3 feet and only grow to about 10 inches tall. We have LOVED seeing this plant bloom for weeks in our new Wild Garden.
