Greetings, I recently sowed seeds in some pots from a Kniphofia hybrid from my parents garden. Some of the seeds have already germinated, and I'm worried that they won't survive the winter. Our Rogue River, OR garden is officially zone 7 with cold, sometimes snowless winters down to 4F some nights. The soil doesn't dry out til late late spring, and in shady areas the ground stays frozen all winter. Would a heat mat and grow lights on my covered porch be enough or should I bring it indoors? I guess if they don't survive I will have learned to sow them in spring, or later in fall. -Travis
