Twilite Prairie Blues False Indigo
Slow to establish flowers are often hidden in foliage or may not flower in year one. Once set, dark chocolate/ purple flowers highlighted by lemon yellow tips on tall stems up to 32″ above the foliage create a striking floral effect. Flowers fade to violet-purple. Blooms approx. three weeks from late May into June. Good cutting flower attracts many types of butterflies.
Foliage interest – color/texture
Clean, blue- green to blue- grey foliage. In partial shade foliage will present overall green. Seed pods create winter interest
Habit and growth rate observations
Nice, clean shrub-like habit exhibits slow growth the first year. Grows 3’ tall by 3’ wide when mature and may create an overall rounded form.
Site preference – soil & light
Evaluation sites ranged from full sun to part shade and evaluator’s noted plants became floppy on shadier sites. Twilite was successful on sites ranging from well drained soil to heavy clay.
Successes and possible drawbacks – how to overcome them
Cut back to the ground in the spring. Some plants attracted Japanese Beetles in 2010 but damage was not enough to disfigure. Cage in early spring if preference is for upright plant.
Notes from growers/retailers
Excellent grower with low maintenance requirements. Finishes on the small side in one season so it may be difficult to find full pots on the retail table
Coreopsis Golden Showers, Geranium sanguinium, Stokesia Mary Gregory, Sedum Neon, Iris hybrids, and ornamental grasses. Use Nepeta at the base to layer in the garden.
Parting SHOT – Overall evaluation results were Good/3.5.
Recommended for the texture and seasonal interest in the garden. Twilite’s large habit creates an excellent backdrop for the deeper perennial border or as a structural accent. Standout glowing purple flower color is attractive to butterflies.
