Winged Spindle Tree Euonymus cornutus var. quinquecornutus
ABOUT
Commonly known as the Spindle Tree, this plant is recognizable by its distinctive foliage and fruit. The leaves are generally oval-shaped with finely serrated edges. They are a deep green color that can turn to reddish-purple or bright red during the fall, providing a visually attractive seasonal display. Flowering in late spring to early summer, the Spindle Tree produces small inconspicuous flowers that are often a greenish-white color. These flowers may not be the most striking feature but they lay the foundation for the most characteristic aspect of the plant. Following the flowering period, the Spindle Tree bears a unique fruit that is noteworthy for its unusual appearance. The capsules are typically pink or a reddish-purple hue and, upon maturity, they split open to reveal seeds. Each seed is encased in a fleshy, bright orange aril that stands out against the color of the capsule. The branching pattern of the Spindle Tree adds to its ornamental value, with stems that can be slightly winged and sometimes exhibit an interesting corky texture. The overall shape of the tree can be quite variable, sometimes upright and other times more spread out, depending on the specific branch structure of the individual plant. With its vibrant autumn leaf color, distinctive fruiting capsules, and interesting branching, the Spindle Tree is a versatile addition to landscapes that can offer visual interest across multiple seasons, despite the absence of large, showy flowers. This adaptability makes it a favored choice for gardens and park settings where year-round appeal is desired.

WaterSpindle tree requires moderate watering, generally about once a week. During the growing season in spring and summer, ensure that the soil remains moist but not waterlogged, by providing approximately 1 gallon of water per week, depending on rainfall and soil drainage. In the fall and winter, you can reduce the frequency as the plant requires less water. It's important to check the top inch of soil for dryness before watering again. Overwatering can cause root rot, so be cautious not to let the Spindle tree sit in standing water.
LightSpindle tree thrives in full sun to partial shade. The ideal spot would offer morning sunlight with some afternoon shade, especially in regions with very hot summers. This plant is adaptable but will have the best growth and foliage color in bright, indirect light or dappled sunlight, which can protect it from the harsh midday sun.
TemperatureSpindle tree prefers a temperate climate, with an ideal temperature range between 60 and 75 degrees Fahrenheit. It can tolerate temperatures as low as 30 degrees Fahrenheit in winter and up to 85 degrees Fahrenheit in summer. Frost can damage the foliage, so it’s best to protect the plant or bring it indoors if temperatures are expected to drop below the minimum threshold.
PruningPrune Spindle tree to maintain shape and encourage bushier growth; the best time for pruning is late winter or early spring before the new growth starts. Light pruning can be done throughout the year to remove dead or damaged branches. It’s generally not necessary to prune more than once a year unless shaping for a specific landscape purpose.
CleaningAs needed
SoilSpindle Tree thrives in well-draining soil with a mix of two parts garden soil, one part peat, and one part perlite or coarse sand. The optimal soil pH for Spindle Tree should be slightly acidic to neutral, around pH 6.0 to 7.0.
RepottingSpindle Trees should be repotted every two to three years to ensure they have enough room for root growth and to replace nutrient-depleted soil.
Humidity & MistingSpindle Tree prefers moderate humidity levels, around 40-60%, to thrive and maintain healthy foliage.

Life cycleThe Spindle Tree (Euonymus cornutus var. quinquecornutus) begins its life as a seed, typically dispersed by wildlife or environmental factors. Germination requires stratification, a process of exposing the seed to cold temperatures to break dormancy, followed by warming temperatures that simulate spring. After germination, the seedling emerges, developing into a juvenile plant with characteristic opposite leaves. As it matures, the Spindle Tree develops woody stems and begins to produce distinctive greenish-yellow flowers during the spring, which are pollinated by insects. Following pollination, the flowers develop into colorful, lobed fruits, which open to reveal attractive seeds with fleshy arils, a feature that assists in seed dispersal. The plant reaches full maturity in several years, completing its life cycle upon senescence and death after reaching reproductive maturity and contributing to the next generation through its seeds.
PropogationPropogation time
Spring to early summer
Propogation: The most popular method of propagating the plant commonly known as Spindle Tree is by seed. The best time for sowing seeds is in the fall after the seeds are harvested. Fresh seeds have a higher germination rate but may need a period of cold stratification to break dormancy. To achieve this, one can mix the seeds with moist sand or peat and refrigerate for about three months. After the cold treatment, the seeds can be sown about half an inch deep in well-drained soil and should germinate in the following spring. Since spindle tree's germination can be unpredictable, it may sometimes take more than one season for seedlings to emerge.
