The deep salmon-red buds of ‘Delft Lace’ open to soft apricot-pink flowers in early summer. The lacy foliage is deep blue-green with red highlights, turning in the fall to display more burgundy. Because of our hot Missouri summers, Astilbes grow best in medium to light shade. If moisture levels are sufficient, they will actually take quite a bit of sun. These plants are deer and rabbit resistant and are the most tolerant Astilbe for Missouri gardens.
Astilbes require moist, highly organic soils. Adding cotton burr compost or manure to the soil at the time of planting will greatly improve conditions. Wait until spring to cut them back so the dead foliage serves as a mulch during winter.
