Lobularia Maritima ‘Snow Princess’ (Snow Princess Sweet Alyssum) is a vigorous, spreading flowering plant renowned for its masses of crisp white, sweetly fragrant blooms. The tiny flowers almost completely cover the green foliage, creating a soft, cascading display that works beautifully along garden borders, pathways, as temporary groundcover, in large containers and in hanging baskets. Unlike many traditional alyssums, ‘Snow Princess’ is sterile, so it does not readily self-seed around the garden.
Heat tolerant, fast growing and exceptionally floriferous, ‘Snow Princess’ provides an extended display with very little grooming required. Deadheading is unnecessary for continuous flowering, although plants can be lightly trimmed when needed to control their vigorous spread. It prefers full sun to part sun, consistently moist but well-drained soil, and regular feeding during active growth. Its fragrance, cascading habit and long flowering performance make it an excellent choice for high-impact garden and container displays.
