Growing Delphiniums from seed

Larkspur (Delphinium elatum)

When starting delphinium seed: freeze the seeds  for 2-3 days in the freezer and then scatter then in a 5 inch pot with damp promix.  

Keep them at 15 degrees C and cover them.  Do not let them dry out.   The cool temperatures start the germination process.  They do not like bottom heat.

  In about 21-30 days sprouts appear, transfer these to 4 inch pots until the leaves grow to the size of a looney.   When the roots appear at the bottom of the pot its time to harden plants outdoors on a deck.  Plants may be planted in the garden while temperatures are still cool.  

  The Ontario Delphinium Club is inviting growers to offer garden space to secure seed production locally for the future as seeds from England may decline.  Web site:   Email:
