Erodiums Many erodiums thrive in rock gardens or in containers with fast-draining soil, and remain more compact and floriferous with full sun. Although they will grow quite well in mildly acidic soil, amending the soil with dolomite makes a great difference in plant size and health. There are some erodiums that will grow in well-drained perennial borders, with at least morning sun, and a few erodiums that prefer shade in all but the mildest summers. In our climate, erodiums close their flowers during the early afternoon, reopening them in the late afternoon.
Information is requested about erodiums that are successful in colder areas.
