Kentucky Coffee Tree Gymnocladus dioica 'Variegata' (v)
ABOUT
Gymnocladus dioica 'Variegata', commonly known as the Variegated Kentucky Coffeetree, is a visually striking plant with distinctive foliage. The unique feature of this cultivar is its variegated leaves that set it apart from the standard species. The leaves are bipinnately compound, meaning they have a feathery, double-layered arrangement of leaflets. Each leaf comprises multiple large leaflets which are edged intricately with creamy white or pale yellow margins that beautifully contrast against the primary green color. The texture of the foliage is somewhat leathery and the leaves have a gentle, matte finish. In the spring and summer, the plant creates a light and airy canopy due to the arrangement of its leaves, which gives it an elegant and slightly tropical appearance. In the fall, the leaves may turn to a warm yellow, bringing a pop of color to the landscape before they drop. The branches of the Variegated Kentucky Coffeetree are typically stout and may display an interesting, rugged bark that adds further visual interest, especially in the winter months when the tree is devoid of leaves. Flowers may be present during the blooming season, but are often not as noticeable or ornamental as the foliage. The overall appearance of the Variegated Kentucky Coffeetree is one of graceful form with a distinctive color pattern, making it a lovely and unusual choice for a garden or landscape, though specific details about its size are omitted pursuant to the provided instructions.

WaterThe American Coffee Tree should be watered deeply but infrequently, allowing the soil to dry out slightly between waterings. In general, water every 1 to 2 weeks, providing about 1 to 1.5 gallons per watering for young trees, and adjusting for mature trees depending on their size and environmental conditions. During the growing season, maintain consistent moisture, but reduce watering in the winter months when the plant is dormant. Overwatering can lead to root rot, so ensure that the plant is in well-draining soil.
LightThe American Coffee Tree prefers full sun to partial shade. It thrives best when it gets at least 6 hours of direct sunlight daily, but can also tolerate light shade. The ideal spot for this tree would be in an open yard or along the edge of a wooded area where it receives ample morning sunlight and some afternoon shade, especially in regions with hotter summer temperatures.
TemperatureThe American Coffee Tree is hardy and can tolerate a wide temperature range, from as low as -30°F in the winter to summer highs up to 100°F. The ideal temperature for promoting optimal growth is between 50°F and 85°F. This tree is well-suited for USDA hardiness zones 3 through 8, and its dormancy can withstand winter chills, making it quite adaptable to colder climates.
PruningPrune the American Coffee Tree to shape it, remove any damaged or diseased limbs, and to promote a strong, healthy structure. The best time to prune this tree is during the late winter to early spring before new growth starts. Pruning can be done annually or as needed, and always make clean cuts with sterilized tools to prevent the spread of disease.

Life cycleThe life of the Eastern Redbud 'Variegata', also known as Gymnocladus dioica 'Variegata', begins with seed germination, triggered by environmental cues such as temperature and moisture. Following germination, the seedling establishes itself and develops into a young sapling. As it grows, the sapling goes through a vegetative stage, producing variegated leaves that are distinctive for this cultivar, and it gradually develops into a mature tree. The tree reaches reproductive maturity and starts to flower, typically producing clusters of showy white and green variegated flowers that attract pollinators. After pollination, the flowers form seed pods, which mature and eventually release seeds to the ground, ensuring the continuation of the species. Throughout its life, the Eastern Redbud 'Variegata' experiences an annual cycle of growth, flowering, and dormancy, particularly in temperate climates.
PropogationPropogation time
Spring-early summer
The most popular method of propagating the Kentucky coffee tree, which is the common name for Gymnocladus dioica 'Variegata' (v), is by seed. The best time to collect seeds is in the fall after the pods have ripened and dried. Once gathered, the seeds require a period of cold stratification to overcome dormancy; this process typically involves soaking the seeds in water for 24 hours and then stratifying them in moist sand or peat moss in the refrigerator for 1-3 months. After stratification, the seeds are sown in well-draining soil and exposed to consistent warmth, about 70 degrees Fahrenheit (approximately 21 degrees Celsius). Germination can be slow, taking several weeks to months, but once the seedlings emerge, they should be grown on in pots until large enough to plant out in their final position.
