Butter and Sugar Siberian Iris

Iris sibirica 'Butter & Sugar'

Plant Details:

Plant Type: Perennial
Plant Family: Iridaceae
Plant Description: This herbaceous perennial produces delicate, creamy white and yellow flowers on top of arching, slender green leaves. The foliage will keep its color into the fall. It grows best in full sun but tolerates part shade. This Iris is perfect for planting in rain gardens, around ponds or water features, or in naturalized areas. It is also deer resistant and tolerant of clay soils.

Maintenance:

Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
