ANEMONE

Anemone includes a rich and varied group of plants ranging in size from alpine rock garden miniatures to tall Japanese anemones grown in borders; bloom extends from very early spring to fall, depending on species.

Most of the anemones described here have fibrous roots or creeping rhizomes or rootstocks, but A. blanda, A. coronaria, and A. x fulgens are grown from tubers requiring special attention. Set out A. blanda in fall; where winter temperatures drop below –10°F/–23°C, apply a thick mulch after first hard frost. Plant A. coronaria and A. x fulgens in fall where they are hardy in the ground; in cooler regions, plant in early spring. In warmer climates, some gardeners soak tubers for a few hours before planting.

Plant tubers scarred side up (look for depressed scar left by base of last year’s stem), setting them 1–2 in. deep and 8–12 in. apart in rich, light, well-drained loam. Or start in flats of damp sand; set out in garden when stems are a few inches tall. Keep soil moist during growth and bloom. Protect from birds until leaves toughen. In high-rainfall areas, excess moisture induces rot.

Tuberous types are best treated as annuals in rainy-summer or warm-winter climates, where they tend to be short lived. Tuberous anemones make good container plants.

Anemone blanda

Native to southeastern Europe. Tubers produce a spreading mat of finely divided, softly hairy leaves (clumps are wider spreading in colder climates). In spring, each 2–8-in.-tall stem bears a sky blue flower 1–1 1/2 in. across. Selections with 2-in. flowers on 10–12-in. plants include ‘Blue Star’, ‘Pink Star’, ‘White Splendor’, and purplish red ‘Radar’. All work well as underplantings for tulips, as groundcover drifts under deciduous shrubs and trees, and naturalized in short grass. Needs partial shade and distinct winter chill for best performance.
