Gardeners' Notes:

This Ed Hume Sensation Mixed Colors seed mix took a while to get going in the spring, but hit their stride in mid summer, filling out and flowering as a vigorous wonder. Popular with hummingbirds, now in October, the plant is looking unfazed by the increasingly tumultuous weather, which heartens me for their sake. Knowing more about Penstemon, however, I might not have chosen this particular cultivar, for its almost gaudy flower colors. Last update: this page claims it's hardy to -30, but my bumper crop of them are all decimated after a winter that went into the teens and single digits. The trimmed back stumps have no roots, and no seedlings around them.
