Trailing Begonia Seeds | Santa Cruz Sunset | Heat & Drought Tolerant | Annual

Trailing Begonia Seeds – Santa Cruz Sunset

The Santa Cruz Sunset Trailing Begonia is a heat- and drought-tolerant annual that delivers a non-stop cascade of vivid red blooms from spring through frost. Unlike traditional begonias that struggle in summer heat, Santa Cruz Sunset was bred specifically to thrive — making it the ideal choice for hanging baskets, container gardens, patio planters, raised beds, and front border edging.

Its trailing habit, compact 6–8 inch height, and bold color make it equally stunning spilling over a planter edge or massed along a garden border. A magnet for bees, butterflies, and hummingbirds, this begonia earns its place in any pollinator-friendly garden design.
