Sweet Alyssum ‘Carpet of Snow’ – The Classic White Pollinator Magnet

‘Carpet of Snow’ remains the gold standard for attracting beneficial insects while creating stunning white drifts throughout your garden. You’ll find this variety delivers consistent performance season after season.

Compact Growth Habit Perfect for Garden Borders

‘Carpet of Snow’ grows just 4-6 inches tall with a spreading habit that reaches 8-12 inches wide. You can plant it along pathways, between vegetable rows, or as edging around flower beds without worrying about it overwhelming neighboring plants. This low-growing nature makes it ideal for front-of-border plantings where taller varieties would block other flowers.

Extended Blooming Period from Spring to Fall

You’ll see first blooms approximately 6-8 weeks after sowing, typically in late spring. The flowers continue producing nectar through summer heat and into fall frost, giving you 4-5 months of continuous attraction for beneficial insects. Regular deadheading isn’t necessary since the small flowers fade naturally and don’t require maintenance.

Attracts Beneficial Wasps and Hover Flies

The tiny white flowers produce abundant nectar that specifically appeals to parasitic wasps and hover flies. These insects need small landing platforms, which ‘Carpet of Snow’s’ clustered blooms provide perfectly. You’ll notice increased populations of these pest predators within 2-3 weeks of peak blooming, creating natural aphid and caterpillar control throughout your garden.

Purple Alyssum ‘Royal Carpet’ – The Vibrant Insect Haven

‘Royal Carpet’ delivers the same beneficial insect attraction as ‘Carpet of Snow’ but adds stunning purple color to your garden design. This variety transforms ordinary spaces into vibrant displays while maintaining exceptional performance for natural pest control.

Rich Purple Blooms That Stand Out in Any Garden

‘Royal Carpet’ produces dense clusters of deep purple flowers that create striking visual contrast against green foliage. The blooms maintain their vibrant color throughout the growing season, unlike some purple varieties that fade in intense sunlight. You’ll get continuous flowering from spring through fall, with each plant reaching 4-6 inches tall and spreading 10-12 inches wide for maximum garden impact.

Exceptional Nectar Production for Beneficial Insects

This purple variety produces abundant nectar that attracts parasitic wasps, hover flies, and lacewings just as effectively as white alyssum. The darker blooms actually enhance visibility for beneficial insects, making your garden a preferred destination for pest predators. Studies show purple alyssum can increase beneficial insect populations by 40-60% compared to gardens without nectar sources.

Drought-Tolerant Qualities for Low-Maintenance Gardens

‘Royal Carpet’ thrives in hot, dry conditions once established, requiring watering only during extended drought periods. The variety performs well in sandy or rocky soils where other flowers struggle, making it perfect for challenging garden spots. You can expect reliable blooming even when rainfall drops below 1 inch per month during summer growing seasons.

Traditional alyssum varieties often stop flowering during peak summer temperatures, but this variety produces nectar for 6-7 months straight. You’ll see beneficial insect populations remain active even during the hottest months when other nectar sources decline.

Larger Flower Clusters for Maximum Insect Appeal

This variety produces flower clusters 25-30% larger than standard alyssum, creating ideal landing platforms for parasitic wasps and hoverflies.
