Rudbeckia hirta

Features

  • Medium producer
  • Pollinator-friendly
  • Suitable for containers

Description

This striking variety boasts large, golden-yellow blooms with dark chocolaty-red centers that look almost like they’ve been hand-painted. No two flowers are exactly the same, and the unique coloring makes these beauties a must-grow.

Details

Plant type: annual
Height: 16 to 20 in
Site: full sun
Days to maturity: 100 to 120 days

Seed Sowing & Growing Notes

Start seed indoors in trays 8 to 10 weeks before last frost; transplant out after all danger of frost has passed.
