As a comment about Bush Penstemon (Keckiella cordifolia), chelle wrote:

Climbing penstemon (Keckiella cordifolia) seedlings are quite cold hardy and adaptable to wide temperature fluctuations. Seedlings transplanted outdoors under high cover have survived and show every sign of continuing to prosper; this batch having been started warm indoors, and then directly exposed to the following:

Day 1, 69°F / 32°F
Day 2, 33°F / 24°F
Day 3, 46°F / 23°F
Day 4, 66°F / 32°F

The seedling exposed to the worst springtime temperature extremes and left to its own devices in its starter cell while we were away on vacation is doing the best overall. Recently transplanted in-ground in one of our hottest, least tended areas, and it appears to be happy. Smiling
