Step by step

  1. Prepare the bed: loosen the soil and mix in an inch or two of compost.
  2. Plant seeds Mar 25 – Apr 29, 1 inch deep (soak seeds overnight first), 4 to 6 inches apart along a trellis.
  3. Keep the soil evenly moist until sprouts appear, which can take one to three weeks in cool soil.
  4. Harvest: Cut stems every couple of days; the more you pick, the more they bloom. Plants stop flowering once pods form.

Varieties that do well here

  • Cupani (very fragrant)
  • Spencer mix
  • Royal Family (more heat-tolerant)

Watch out for

A classic cut flower that loves cool Northwest springs. Sow early, give them a trellis and pick often. The seeds are toxic, so these are for flowers only.
