Common Name: Bearded Penstemon
This striking perennial draws its name from contrasting gemstones—onyx for its deep, dark foliage and pearls for its delicate lavender blooms with creamy white centers. The flowers appear nearly white from afar, creating an elegant two-tone effect. A taller, more robust cultivar than 'Blackbeard', it offers fuller growth and softer flower tones, making it an excellent choice for adding height and subtle color contrast to garden beds.
A resilient performer that thrives in heat, humidity, and cold climates alike, this Penstemon delivers season-long color without fuss. Exceptionally drought tolerant and disease-resistant, it requires minimal maintenance once established. Position in full sun to encourage robust blooms and attract hummingbirds, who are drawn to its abundant nectar. A low-maintenance choice for gardeners seeking reliable, pollinator-friendly perennials.

Order Details & Policies
No Returns But Replacements
We do not do returns or offer warranties, unfortunately. We simply can't guarantee the future of plants after they leave our shop and are in your care. But the health of our plants upon arrival is something we'll stand by.
Shipping can stress plants. If there are any issues with your plants when you receive them, send us a chat message from our website. We can issue store credits or send replacements.
Also, our starter perennials are small plants. We do not issue refunds because they are smaller than expected. For more details about plant sizes, see Starter Perennials Shipped Trimmed.
Starter Perennials Ship Trimmed
Starters are small, young plants or plugs, bare roots and bulbs. We do not ship mature plants in containers. We will often trim back growth on our perennial plugs to reduce stress on the plants during travel. Trimming does not hurt the plants. They'll bounce back with new growth. You'll receive your plants carefully wrapped and prepared for shipping in a box.
Plant Sizes
Starter perennials are smaller because they are young. Bare roots and bulbs speak for themselves. We have plug sizes ranging from 1-2 inches x 2-4 inches, although some hostas come in larger sizes.
These are not yet plants at maturity as seen in many of the photos on our store. We have photos of real starter plants on some listings and we are working to post more starter photos this year in 2026. We're adding plug sizes to the plant pages, too. Bear with us as we update all our plant detail pages so you are better informed. In the meantime, if you need more details or a photo of an actual starter, send us a message in our chat.
Delivery
Your order should arrive within 7-14 days. Occasionally, we may hold an order so that we can fulfill it with new inventory we are expecting to receive. Just send us a chat if you need a status update.
