Adding fresh, long-lasting color to the summer garden, Vitex agnus-castus 'Shoal Creek' (Chaste Tree) is a deciduous, vase-shaped shrub noted for its long blooming season and disease-resistant foliage. Growing with a dense, upright habit, it features sage-scented, grayish-green palmate (hand-shaped) leaves with five to seven leaflets and silvery undersides that flicker in the wind and produce a lovely effect. Highly ornamental, spectacular sprays, 12 in. long (30 cm), of small, fragrant, vibrant blue-violet flowers appear from summer to fall, attracting scores of butterflies, hummingbirds, and bees. Fast-growing and low maintenance, 'Shoal Creek' develops a naturally well-balanced shape and doesn't require pruning. A wonderful addition to summer landscape color without the work involved with bedding plants!

• Exceptionally vigorous, 'Shoal Creek' grows, with a spreading habit, up to 4-15 ft. tall (120 - 450 cm) and 4-12 ft. wide (120-360 cm). This versatile plant can be trained as a large shrub or small multi-trunked tree. In cold winter areas, Chaste Tree grows only as a modest-sized perennial shrub because it often suffers winter dieback or dies to the ground. Even though plants may die to the ground (in Zone 5-6 winters), the roots often survive and push up as much as 4-7 ft. (120-210 cm) of new growth the following year. 
• Winner of the Gold Medal Award of The Pennsylvania Horticultural Society.
• A full sun lover, this plant is easily grown in loose, medium moisture, well-drained soils. Thrives in heat. Tolerates partial shade, but the best flower production occurs in full sun. In cold areas, provide a sheltered location such as a west- or south-facing building wall to protect it from the cold. Drought tolerant once established.
• Perfect as a specimen plant in the lawn or in shrub borders, cottage gardens, butterfly gardens, and foundation plantings. Impressive when planted in a row along a property line or a driveway and lovely as a small patio tree.
•  No serious insect or disease problems. May occasionally develop fungal problems, such as leaf spots or root rot.
• Deer resistant. Salt tolerant.
• Blooms on new growth from the current season. Cutting back side branches by 1/3 during the first two or three years may help promote dense branch growth. Cut back in winter or early spring
