Snow Dome™ Iberis

Snow Dome™ is Syngenta Flowers’ Iberis sempervirens selection, product code 70103625. It forms a medium-vigor mound with extra-large white flowers on sturdy, branching stems; the breeder lists flowering from mid spring through summer and a mature range of 6–10 inches tall by 10–12 inches wide. ([Syngenta Flowers](https://www.syngentaflowers.com/ams/product/flower/70103625)) ## Garden Use Its compact footprint suits a border front, walkway edge, sunny rock garden, or container. Candytuft’s narrow, dark green foliage remains evergreen in warmer climates and may be semi-evergreen in colder areas. ([NC State Extension](https://plants.ces.ncsu.edu/plants/iberis-sempervirens/)) ## Growing Conditions Grow in full sun and well-drained soil. The species tolerates moist to slightly dry conditions, but wet, poorly drained soil can cause crown problems. ([NC State Extension](https://plants.ces.ncsu.edu/plants/iberis-sempervirens/)) ## Maintenance After bloom, shear back by about one-third to encourage fresh growth and maintain the mound. Mulch in colder climates if winter foliage needs protection.
