You will get a higher germination rate if you will cold treat these for 30 days prior to sowing. Mix your seeds with 1/4 cup of sand, peat, or vermiculite and place into a baggie. Add 1 teaspoon of water and place in your fridge (not your freezer).

After this cold treatment sow them in pots about 10 weeks before your last frost in spring. These need light to germinate so sow on the surface of your potting material and lightly dust with sand or vermiculite. Once seedlings are 2-3" tall slowly introduce outdoors and transplant in spring after your last frost.

You can also direct sow these in early winter, but they are slow growing perennials and tend to get overwhelmed by weeds.

Penstemon is very cold hardy, but for zones 3 and 4 where temps can drop below -10 degrees you can mulch them in late winter to protect them, or pull the root balls and over winter in a protected area.

Conversely in very hot zones like 8 and 9 you can help them out by planting your seedlings in an area where you get late afternoon shade.
