More About Lobularia ‘Stream™ Compact Rose’

Lobularia ‘Stream™ Compact Rose’ produces soft rose-pink flower clusters that bring a gentle, romantic tone to spring containers and garden edges. The blooms are held densely over the foliage, creating a uniform carpet of color without the loose, spreading habit common to older alyssum varieties.

As part of the Stream™ series, this selection was bred for tight, controlled growth and improved heat tolerance, allowing it to perform longer into the season while maintaining a neat, intentional appearance.

Why We Like It (Our Trials)

In our trials, ‘Stream™ Compact Rose’ has been especially reliable in early-season plantings, holding its compact shape without stretching and flowering consistently as temperatures warm. It rebounds well after brief heat stress and continues to look tidy with minimal maintenance.

We especially appreciate its scale and color. The rose-pink blooms pair beautifully with whites, purples, soft blues, and silvery foliage, making it an excellent choice for detailed container designs and clean garden edging.

Lobularia ‘Stream™ Compact Rose’ vs. Other Alyssum

Compared to spreading alyssum types, ‘Stream™ Compact Rose’ offers a much more refined, space-efficient habit, ideal for tight plantings.

When compared to the Easy Breezy™ series, this variety stays smaller and more compact, while still delivering dependable bloom and improved heat performance. For gardeners seeking a compact, heat-tolerant alyssum with soft pink color, Lobularia ‘Stream™ Compact Rose’ is an excellent choice.
