Snow Princess® Sweet Alyssum

Snow Princess® is a vigorous, trailing sweet alyssum with white, fragrant flowers that can continue from planting until hard frost. Proven Winners lists it at 10–16 inches high with a 24–48 inch spread, and recommends it for containers and landscape use. ## Garden Use The [Snow Princess plant profile from Proven Winners](https://www.provenwinners.com/plants/lobularia/snow-princess-sweet-alyssum-lobularia) describes this exact selection as heat and cold tolerant, with abundant white flowers that attract bees and butterflies. Its long trailing stems suit large baskets, window boxes and planters, while its spreading habit can cover bed edges or serve as seasonal ground cover. The profile gives an 18–24 inch spacing recommendation separately from its 24–48 inch spread; spacing is not mature width. ## Growing Conditions The breeder lists part sun to sun, average soil and water, good drainage, and USDA zones 9a–11b. It notes that plants prefer evenly moist soil and may need frequent watering in warm-weather baskets. For related sweet alyssum, [University of Wisconsin Horticulture](https://hort.extension.wisc.edu/articles/sweet-alyssum-lobularia-maritima/) describes a shallow-rooted, sun-loving annual that flowers through the growing season and attracts beneficial insects. Use that species-level guidance with local conditions in mind. ## Maintenance Keep the root zone evenly moist, especially in hanging baskets and small pots; larger containers are easier to keep watered. Deadheading is unnecessary for continued bloom. Trim trailing stems if they encroach on walkways or look untidy, and use a balanced fertilizer according to its label when needed for container growth.
