The common name for this plant is Storm Cloud Amsonia and the botanical name is Amsonia tabernaemontana 'Storm Cloud'. These heat-loving, drought-tolerant plants thrive in hot weather conditions. There are blue colored flowers that bloom during spring to summer. While no plants are truly deer proof, these plants are deer resistant.

In garden planters, use this in the thriller role. Those are plants with drama and that add height or a vertical element to the combination. These are typically in the center or the back of the container. Stays short and perfect as a border plant, which are perfect placed along the edge of a garden bed or path. This plant works great in mass planting or as focal point in your landscaping. The Storm Cloud Amsonia typically grows 2-2.5 feet tall, and 38-42 inches wide. For best plant health and results, space these plants 2.5-3 feet apart, center on center. The growth habit is mounded. The Storm Cloud Amsonia is winter hardy & summer tolerant in growing zones 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b.

    by the beach

    Posted by Liz Rosa on Mar 21st 2019

    I planted a few of these by my beach, in a location that gets full sun the entire day. These plants just thrived last summer, even when I forgot to water them regularly. The flowers in the picture don't do it justice. The blue really stands out, especially next to the dark mulch I had around the plants and the green leaves. Seems like I picked the perfect location for these.
