Penstemon are an American native with colorful tubular bell-shaped flowers. Will attract butterflies and hummingbirds and does well in a drier climate. Drought resistant once established. Waxy green foliage stays lush through summer's heat. Avoid too moist (wet feet). Songbirds feast on the seed in fall and winter.
Best in loose, gravelly soil with good drainage. Pinching back taller varieties when about 12" tall will produce more compact plants. Can be divided every 3-4 years in spring by digging mature rhizomes and replanting. Will self sow. Foliage can be trimmed after blooming to freshen. Clean up in fall or spring. May benefit from loose winter mulch in colder zones.
Our plants are all grown in plantable fiber pots that grow incredibly vigorous plants, eliminate transplant shock, and are 100% biodegradable. They have tremendous advantages over plastic pots.
