Growing and Saving the Seed Of Hyssop

Latin name Agastache hybrida is a perennial member of the mint family that blooms in the first year. In its first year the blooms will appear in mid-summer, and the next spring it will bloom earlier. Hardy from USDA zones 4-9.



Native to North America. A super pollinator attractor beloved by butterflies and bees. The bright, fragrant flowers make a long-lasting cut flower, too!


  • Ornamental.
  • Cut flowers.
  • A favorite of pollinators.




  • Surface sow seeds and just gently press into soil, as light aids germination.
  • Start indoors 8-10 weeks before last frost and transplant out after last chance of frost has passed, or direct seed outdoors after last frost has passed.
  • Ideal germination temperature is 65-70 F.


  • Prefers full sun but will tolerate some shade.
  • Plants require well-drained soil in order to overwinter as perennials. (They will struggle to survive winter when planted in compacted, boggy soil.
  • Space plants 12-14 inches apart.
  • Plants are relatively drought tolerant and as long is soil is well drained, and they will not fuss about soil or fertility.


  • Typically a pest- and disease-free plant.
  • Plants will require well-drained soil in order to survive over the winter. They will not tolerate standing water in winter.


  • Seed saving is unreliable from agastache, but it is very easy to take cuttings in either fall or spring.
  • In fall, snip cuttings and root, keeping indoors as a house plant and treat as a mother plant for propagation in spring.
  • Spring cuttings are even easier; simply take green wood cuttings or woody cuttings to propagate.
