More About Lobularia ‘Stream™ Compact White’

Lobularia ‘Stream™ Compact White’ produces crisp, bright white flower clusters on a tight, uniform plant. The blooms are densely packed, creating a clean, polished look that works beautifully as a filler or edging plant without becoming loose or overgrown. As part of the Stream™ series, this variety was bred for compact growth, uniform habit, and better heat tolerance, allowing it to perform longer into the season than traditional alyssum.

Why We Like It (Our Trials)

In our trials, ‘Stream™ Compact White’ has been exceptionally dependable in spring and early-summer plantings. It holds its compact shape without stretching, flowers continuously, and rebounds well after brief heat stress. We especially appreciate its versatility. The pure white blooms brighten mixed containers, soften bold color combinations, and provide subtle fragrance near walkways and seating areas.

Stream™ Compact White vs. Other Sweet Alyssum

‘Stream™ Compact White’ is the cleanest and most formal option within the Stream™ Series, offering bright white blooms on an ultra-uniform plant. Compared to Compact Rose and Compact Purple, it blends more easily into structured designs while highlighting nearby colors. Its restrained growth keeps borders looking sharp even as surrounding plants mature and shift. Like the rest of the series, Compact White stays tight and predictable.

Compared to Yolo White, it is more compact and less forgiving of spacing errors. This tighter habit makes Compact White better suited for symmetrical layouts and high-visibility planting areas. Against Easy Breezy™ White, Compact White trades spill for precision and excels in formal borders. Gardeners choose Stream™ Compact White when neatness and consistency are the top priorities.
