Penstemon digitalis ‘Gold Foil’ (Foxglove Penstemon) [15 Seeds]
Germination Information: I recommend these seeds for experienced seed-starters only, because they may require some patience. The easiest approach is to surface-sow (do not cover) the seeds in fall to late winter, setting them outdoors in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring.
If you sow after February, set the pot in a plastic bag in your refrigerator for about 2 months before moving it to a warm, bright place for germination. (Remove the bag if the pot will be exposed to any direct sun.)
It is possible that these seeds could germinate if you sow them in warm, moist, bright conditions. But if you try that and no seedlings appear within 3 weeks or so, then try the refrigerator-chilling approach above before moving them back to warmth and light.
By the time the seedlings have a few true leaves, you may notice that some of them are distinctly green and others are yellowish green. The yellowish green ones are most likely to have the brightest foliage in following years, but I suggest also keeping the greener seedlings for a year or two, just to see if they too will be yellow in spring or if they will be consistently green (in the latter case, discard those plants or move them elsewhere).
