What was checked
Mature height and spread, hardiness zones, sun and the trait tags were checked against named botanical sources for this plant. The bloom months and water need on this page were not, and each fact above says which. The planting, spacing and size sections are derived from these checked facts by a fixed rule, not checked separately, and the plant type is the library's own classification.
When to plant Sun Parasol Sunbeam
Sun Parasol Sunbeam sits in a nearly frost-free range (zones 10 to 11): plant it in the cool season, fall through late winter, and let the mild months settle its roots. On the calendar that means October or November, or January or February. Once settled, it blooms from June to October.
