More About Angelonia ‘Alonia™ Big Snow’

Angelonia ‘Alonia™ Big Snow’ is a premium summer snapdragon selection known for its oversized, crisp white flower spikes and outstanding performance in heat and humidity. The blooms are noticeably larger than standard angelonia, creating bold vertical accents that stay clean and bright even during the hottest months of summer.

Part of the Alonia™ Big series, this variety was bred for vigorous growth, strong branching, and continuous flowering without deadheading. Unlike many white annuals that can yellow or thin out under stress, ‘Big Snow’ maintains a fresh, polished look all season long, making it a dependable choice for high-impact plantings.

Why We Like It (Our Trials)

In our trials, ‘Alonia™ Big Snow’ has been exceptionally reliable in full sun, thriving through prolonged heat and humidity with minimal maintenance. It establishes quickly, resists stretching, and keeps producing fresh flower spikes from planting until frost.

We especially like its versatility. It works just as well in containers and mixed borders as it does in large mass plantings, where the bright white blooms provide contrast and visual relief among bold summer colors. Pollinators—especially bees—visit regularly, and the foliage stays clean with very few disease or pest issues.

Angelonia ‘Alonia™ Big Snow’ vs. Other Angelonia Varieties

Compared to standard angelonia selections, ‘Alonia™ Big Snow’ offers larger flowers, stronger stems, and a more upright, refined habit. While smaller varieties excel as fillers, ‘Big Snow’ functions as a true structural plant, adding height and presence to summer displays.

When paired with colorful Alonia™ varieties in purples, pinks, or blues, ‘Big Snow’ acts as the perfect neutral anchor. For gardeners and designers looking for a heat-proof white annual that delivers season-long performance with minimal effort, Angelonia ‘Alonia™ Big Snow’ is one of the best options available.
