Heuchera americana
Many cultivars of this plant exist in the nursery trade, as its foliage color is easily manipulated; the straight-species will also see some red coloration, especially along leaf venation in cool weather. Not much information is known about the insect visitors to the tiny pale-green flowers, but it supports at least one specialist bee, Colletes aestivalis, and likely others with its nectar reward. Mammalian herbivores ignore the toxic foliage, which has a very nice mounding shape; this would make an excellent groundcover. Plants can be divided every 3 years or so, which probably improves vigor.
American Alumroot needs moist but well drained soil with plenty of organic matter and its shallow, fibrous root system allows it to thrive in rock gardens. This easy-to-grow plant is juglone-tolerant and will grow under the canopy of Black Walnut trees. Foliage may scorch if planted in full sun. Other common names include Coral Bells and Rock Geranium, the latter referring to the resemblance of the basal foliage to that of Geranium, although the two are unrelated.
