Description

A tree that produces blue flowers? Yes! Some people call this the “Sage Tree” because its spikes of violet-blue flowers resemble those of blue sages (Salvia). When young and in bloom many also mistake it for a butterfly bush.

The ‘Shoal Creek’ Chaste Tree, Vitex agnus-castus, was introduced by Goodness Grows near Athens, Georgia. It was propagated from a seedling that was selected for its larger, more vibrant flower spikes, its faster growth rate, and its superior cold hardiness. In early summer spikes of lilac blooms appear at the ends of every stem on the tree, which grows 15 to 20 feet tall with an equal width. Pruning after the first flowers fade often encourages a second bloom cycle in late summer through early fall.

The flowers of the Chaste Tree are very attractive to butterflies, hummingbirds and beneficial pollinating bees. If the spent flowers are left on the tree in fall, seeds will form that Cardinals and other birds absolutely love to dine on during the winter months. So, if you are into feeding the birds, this is a must have tree that will provide a free source of food for them.

Landscape & Garden Uses

Depending on your preference, Shoal Creek Chaste Tree quickly grows into a multi- or single-trunk large shrub or small tree to about 15 to 20 feet tall and wide. In design, we use it as we do upright Japanese maple: as a focal point specimen tree, in groupings of three or more where space allows, or to frame in the corners of homes and other structures. Grown as a shrub, when planted in straight or staggered rows it makes a colorful hedge, and looks especially nice around garden ponds and other bodies of water and in rock gardens. A worthy addition to bird, butterfly, and pollination gardens!

Suggested Spacing: 8 to 10 feet apart for solid hedge; 22 feet or more apart for space between plants

Growing Preferences

Shoal Creek Chaste Tree will grow in most any moist but well-drained soil of average fertility, including clay soil. soil, including clay soils. it will tolerate somewhat wet conditions and is also drought tolerant when established. No pruning necessary however responds well to it for shaping purposes or to control size. Deadheading spent flowers encourages a heavier rebloom.

Note: The chaste tree is cold hardy in USDA Zones 5a-9b. In USDA Zones 5 and 6 young plants might die back to the ground during an unusually cold winter. If so, cut it back to the ground like you would a butterfly bush and it will quickly regrow to a 4 to 6′ shrub.

I’ve been ordering plants online for some 20 years now (lived in remote regions or wanted hard to find plants trees etc)
This is a beautiful specimen! Big solid root system and packed well and healthy. I can see that a large branch was cut off so this will be ready to take off after I plant it! I am very pleased!
