Penstemon 'Onyx And Pearls' (PP32,613)
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 dry winter mulch in colder zones.
Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
