Best heat-tolerant annual for gardeners seeking low-maintenance, long-lasting white blooms.

These seeds finally solve the problem of wilting summer displays by thriving in the kind of heat that kills off lesser annuals. You sacrifice the variety of a mixed bed for a singular, high-performance white bloom that stays crisp and glossy even when the temperature spikes.

Who it's for

  • Container gardeners seeking dramatic, full-bodied floral displays
  • Busy homeowners wanting low-maintenance, season-long color
  • Professional growers requiring predictable, uniform plant development

Who should skip it

  • Budget-conscious gardeners planning large-scale landscape installations
  • Novice gardeners lacking specialized seed-starting equipment
