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.

Stream™ Compact Rose vs. Other Sweet Alyssum

Within the Stream™ Series, ‘Compact Rose’ offers the warmest tone, providing soft pink blooms on a tight, uniform plant. Compared to Compact White and Compact Purple it feels more delicate and romantic while maintaining the same controlled growth habit. The softer coloration makes it especially effective in pastel palettes and spring-focused plantings. Like all Stream™ varieties, Compact Rose has excellent uniformity and tidiness.

Compared to the Yolo Series, Compact Rose stays smaller and more precise. This precision makes it ideal for borders, window boxes, and small containers where scale is critical. Against the Easy Breezy™ Series, Compact Rose is dramatically less trailing and easier to manage. Among pink alyssums, it’s one of the most refined. Gardeners value this variety for clean edges and subtle color where control matters most.
