White Stream Sweet Alyssum

Lobularia maritima 'White Stream' (Lobularia maritima 'White Stream') is a beautifully fragrant, prolific, and irresistibly charming sweet alyssum that produces a virtually uninterrupted cascade of tiny, pristine white flowers in such generous, dense abundance that the fine-textured, silver-green foliage beneath disappears entirely beneath a honeyed, snow-white carpet of bloom from planting through the first frost. Sweet alyssum has been treasured in gardens for centuries for precisely the qualities that 'White Stream' exemplifies so fully — a clean, luminous white that brightens every surrounding color, a pervasive, sweet, honey-like fragrance released continuously throughout the day and evening, and a freely spreading, ground-hugging habit that fills pathways, container edges, and border gaps with naturalistic, effortless grace. 'White Stream' is a particularly vigorous and heat-tolerant selection that maintains its prolific bloom performance through the warmest months of the growing season with admirable consistency.

This professional-grade 4" plant arrives with a healthy, well-established root system cultivated through professional horticultural practices — ready to spread and establish quickly into its characteristic low, fragrant, freely flowering mat. 'White Stream' excels as a fragrant, weed-suppressing edging plant along sunny pathways and border margins, as a cascading spiller in containers and hanging baskets, as a gap-filling ground cover in mixed annual and perennial beds, and as a naturalistic underplanting for taller border companions where its honey-scented white carpet provides a soft, fragrant, low-growing base layer of continuous color and sensory richness.

• Dense, Honey-Scented White Flower Carpet: Tiny, pristine white flowers produced in such prolific, continuous abundance that they form a virtually solid carpet of honey-scented white — a fragrant, luminous, season-long display that combines freely spreading ground-cover coverage with a pervasive, sweet fragrance that perfumes pathways, borders, and outdoor spaces throughout the day and evening.
• Pervasive Sweet Honey Fragrance: The famous, beloved sweet honey-like scent of alyssum is released continuously throughout the day and into the evening — one of the most universally appreciated and accessible garden fragrances available, transforming sunny borders, patio edges, and pathway margins into a daily sensory pleasure from late spring through frost.
• Vigorous Heat-Tolerant Performance: A particularly heat-tolerant 'White Stream' selection that maintains prolific white bloom through the warmest months with greater consistency than many standard alyssum varieties — continuing its fragrant white carpet display during the peak summer heat when less vigorous selections may slow their flowering.
• Versatile Edging, Spiller & Gap-Filler: The low, freely spreading habit adapts beautifully to multiple garden roles — pathway edging, container spillover, hanging basket trailer, paving gap filler, and naturalistic border underplanting — making 'White Stream' one of the most practically versatile and consistently useful low-growing annuals available for the warm-season garden.
• Beneficial Insect Magnet: The densely produced, honey-scented white flowers are a rich, accessible nectar source that attracts hoverflies, parasitic wasps, native bees, and butterflies in impressive numbers — making 'White Stream' one of the most ecologically valuable flowering annuals for the garden, supporting beneficial insect populations that naturally control pest species.

These 4" healthy live plants thrive in full sun to partial shade with well-drained, average to lean soil and moderate moisture; avoid overly rich, fertile conditions that promote excessive leafy growth at the expense of prolific fragrant bloom. Water regularly during establishment, then water moderately. Treat as a cool-season to warm-season annual; tolerates light frost and performs most prolifically in mild to warm temperatures. Transplant outdoors after the last frost date. Self-seeds freely in favorable conditions. USDA Hardiness Zones 5–9 as a perennial in mild climates; grown as an annual in most regions. Mature height: 3–6 inches; spread: 8–16 inches. Bloom time: late spring through first frost.
