Blue Rock Candy Penstemon lines up short, upright spikes of lavender-blue bells, every one of them opening on a crisp white throat, above a neat basal clump. Penstemon barbatus Rock Candy Blue comes as a live 4-inch plant, buds and open flowers already showing.

Under a foot tall, it belongs at the front of a sunny border, along a walkway, or in a container where the flowers land at eye level from a chair. It carries on from spring into early autumn, pulls in bees, butterflies and hummingbirds, and the spikes are the right length for small arrangements. Water it through the first season, then ease off; settled plants would rather run dry.

Fun fact: the old name beard tongue points to a fifth stamen that carries no pollen and often wears a tuft of hairs at the throat of the flower.

We use expedited shipping policies to protect plant health and minimize plant stress in transit.  All plants are in transit for only 1-3 days. (This does not guarantee 3-day delivery as orders are not always packed and sent out on the day of your order.) We send out deliveries on a weekly schedule to ensure quick transit times, so your order may not be packaged and shipped until later in the week. For instance, we may hold shipments to avoid weekend delays that keep plants in transit for longer.

All packaging includes eco-friendly material and our shipping methods are tested regularly to ensure plants arrive healthy upon arrival.

Additionally, any delays or damages in shipping are covered by our Healthy Plant Guarantee.

If you're plants arrived damaged, we will happily replace them for free!

Please contact us, send a picture, and detail any damage, so that we can continue to improve our shipping process and make sure you receive the healthy plants you paid for.
