Bupleurum Griffithi

Light green or chartreuse filler for early summer flower arrangements. Also makes a nice dried flower. Plant your first crop early, and add an additional succession or two. It is likely to reseed where you plant them for future harvest. Also known as Griffithii, Thoroughwax, and Hare's Ear. Days to maturity: 80-90 Seeds per pack: 70-75 Germination rate: 0% (total viability: 79%) on 02/03/2026 (read more about viability) Planting / harvesting notes Sow 5-8 weeks early in 72 or 128 cell flats. Harden off before transplanting into the garden. Or direct sow into cool soil (6 weeks before last frost) for best results. Prefers full or partial sun. Space plants at 6-10" apart and provide support in windy locations.  Seed keeping notes Allow the seeds to dry and turn brown/dark purple/black on their stems. They are ready when they easily shatter into a bucket when the spent flowers are squeezed. Use screens and winnowing to remove the chaff from the seeds. Store in a cool, dark place when fully dry.
