Heuchera 'Lime Rickey' 'Lime Rickey' was introduced by master plantsman Dan Heims, so you know it's going to perform well. I find that it makes a spectacular edging -- its bright coloring is particularly effective in the early evening, when other plants are falling into shadow. Space plants about 18 inches apart and water well the first season to get them established. They can tolerate up to a half day of sunshine, provided the sun is in the morning rather than the stronger afternoon. Dappled overhead shade is fine as well. An excellent overplanting for bulbs. Zones 4-9.
