I recently purchased seed from a much warmer climate which then made me wonder whether the daylily seedlings produced from this seed would be cold hardy. In terms of growing seed is cold hardiness (or heat tolerance) dependent upon where the parent plants are grown or dependent on the foliage type of the parent plants (Evergreen vs. Dormant)? Or does it depend upon whether the parent plants are cold hardy regardless of foliage type or location grown? Does the location where the seed is sown play any role in this?
