About this plant
The Shoal Creek Chaste Tree is a deciduous large shrub or small ornamental tree prized for its abundant lavender-blue to violet-blue flower panicles that bloom from late spring through summer. Its fast growth, low water needs once established, and high deer resistance make it ideal for mixed borders, specimen plantings, pollinator gardens, and xeriscape landscapes where reliable summer color is valued. It can self-seed and is considered weedy in parts of the southeastern US, so check your state's invasive plant list before planting.
Your Shoal Creek Chaste Tree arrives as a nursery-grown plant in its container, ready to transplant into prepared garden soil with good drainage. Plant on arrival or within a few days, water thoroughly to settle the soil, and keep consistently moist for the first week as the roots establish in their new location.
Shoal Creek Chaste Tree for Dry Sun
It matures near 10 to 15 feet tall with similar width.
Open-sun specimen
Stand it alone in open sun and let the lavender-blue panicles carry late spring into summer.
Screen row
Plant 8 to 12 feet apart for a fast-growing hedge that thickens over a few seasons.
Water-wise bed
After establishment it handles drought, so pair it with muhly grass, lantana and Russian sage.
Young container
Small plants live in a pot for a time, then belong in the ground.
Not ideal for: Soggy ground and part shade both cut into flowering and form.
Good to know: Can self-seed and turn weedy in the Southeast, so check your state's invasive plant list.

| #1 / 1 Gallon | A trade one gallon pot (about 6.5 inches). One to two seasons older than a quart, with an established root system. |
| #2 / 2 Gallon | A trade two gallon pot. Common for peonies and perennials that need root room; usually blooms the first or second year. |

Questions before you buy
Which size should I choose?
The QT and 1-Gallon sizes are ideal for starting a young plant that will reach its mature size when established in the landscape. The 2 and 3-Gallon containers offer more immediate visual presence and plants that will fill their space quicker. Choose based on your budget and preferred timeline to mature size.
When is the best time to plant my Shoal Creek Chaste Tree?
Plant it in spring or fall. Container-grown plants can be transplanted during the growing season or in fall, and planting earlier in the season gives roots more time to establish before winter dormancy.
How large does a Shoal Creek Chaste Tree grow?
This cultivar typically reaches 10 to 15 feet tall and equally wide at maturity, occasionally reaching 20 feet in ideal conditions in warmer zones. Growth is fast, roughly 2 to 3 feet per year, so the plant reaches full mature size in about 3 to 5 years.
How much sun does this chaste tree need?
Shoal Creek Chaste Tree thrives in full sun, meaning 6 or more hours of direct sun daily. Flowering and plant form noticeably decline in part shade, so choose a location with abundant sun for the best results.
What climate zones is this chaste tree hardy in?
The Shoal Creek Chaste Tree is hardy in USDA zones 6 to 9. It is also root-hardy into zone 5 in some reports, where it may die back to the ground in winter and regrow from the roots in spring.
What should I do in the first year after planting?
Water regularly while the plant is young to encourage root establishment, then transition to low or moderate watering once it is established. Provide full sun and well-drained soil. Deadheading spent flower panicles can encourage rebloom flushes throughout the summer.
