Bupleurum ‘Griffithi’

Bupleurum rotundifolium

Features

  • Easy to grow
  • Foliage & Filler
  • One-hit wonder

Description

The bright chartreuse blooms of this easy-to-grow filler add sparkle and interest to early summer arrangements. I love to combine the airy stems with brilliant jewel tones or simple clean whites and greens. For an extended harvest, sow successions of seeds every 2 to 3 weeks.

Details

Plant type: hardy annual
Height: 36 to 40 in
Site: full sun
Days to maturity: 80 to 90 days
Plant spacing: 6 to 9 in
Pinch: do not pinch

Seed Sowing & Growing Notes

In mild areas, seed can be sown directly into the garden in the fall. Everywhere else, direct-seed into the garden 6 weeks before last frost. Seed can be tricky to start indoors, so pop seeds into the freezer for 10 to 14 days before sowing to speed up germination. Don’t pinch plants.

Harvesting/Vase Life

Harvest when flowers are fully open to avoid wilting. Expect a vase life of 8 to 10 days.
