Wintersweet Bonsai Blooms in Winter with Intense Fragrance: Care and Cultivar Characteristics

Wintersweet bonsai is a traditional stump bonsai made with wintersweet as the material. Wintersweet (Chimonanthus praecox) is not a plum; botanically it belongs to the family Calycanthaceae, and it gets its name because its petals have a lustrous, wax-like texture and it mostly blooms in the cold twelfth lunar month. When the hundred flowers wither in winter, wintersweet instead puts forth buds against the cold, with small golden-yellow flowers dotting the branches and a fresh, lasting fragrance, making it an excellent choice for winter flower viewing.

Quite a few wintersweet cultivars are suitable for making bonsai, commonly including pure-heart wintersweet, qingkou wintersweet and dog-tooth wintersweet. Pure-heart wintersweet has flowers that are pure yellow both inside and out, with a rich fragrance and high ornamental value; qingkou wintersweet has rounded, blunt petals shaped like a qingkou, and is also much favored by bonsai enthusiasts; dog-tooth wintersweet has small, pale flowers and is mostly used as rootstock, from which ideal ornamental cultivars can be developed through grafting.

In caring for wintersweet bonsai, the key is plenty of sun and little watering. It likes a sunny environment and is fairly drought-tolerant, and it fears waterlogging in the pot above all, so watering should follow the principle of not watering until dry, and watering thoroughly when you do. After the flowers fade, prune promptly, cutting away spent flower branches, overly dense branches and leggy growth, which both maintains the tree shape and reduces nutrient consumption, laying a good foundation for blooming the next year.

The styling of wintersweet bonsai emphasizes an antique, rugged look, often using the natural posture of old stumps combined with wiring, pruning and other techniques to create diverse forms such as curved trunks and slanting trunks. An old-stump wintersweet cultivated over many years, with sturdy branches and sparse shadows slanting across, paired with golden flowers blooming in winter, has a uniquely sparse and elegant charm, and is a delight to the eye whether placed in a courtyard or on a desk.
