Liquidambar formosana aka Formosan Sweet Gum

Taxonomy

Genus Liquidambar Family Altingiaceae Order Saxifragales Class Magnoliopsida Phylum Tracheophyta
Liquidambar formosana, also known as the Formosan gum, Chinese sweet gum, Taiwanese sweet gum, or Formosa sweet gum, is a deciduous tree native to East Asia. It can reach heights of 15-40m and has a broadly conical or large growth habit. The leaves of this tree are three-lobed, unlike most American Liquidambar species, and turn shades of red, orange, and purple in autumn, adding to its visual appeal. In late spring, insignificant flowers appear, followed by spiky fruit capsules in autumn that can persist on the tree into winter. The L. formosana is hardier than the species, making it more suitable for our climate. Its roots can be aggressive, and its branches often have corky projections. The individual flowers are unisexual, but both male and female flowers can be found on the same plant. Male flowers are in catkins, while female flowers form dense spherical heads, and the fruit is burr-like due to the persistent styles.

How to care for Formosan Sweet Gum

Difficulty

Formosan Sweet Gum is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Water

Formosan Sweet Gum should be watered regularly, allowing the soil to dry out between waterings.

Soil

Formosan Sweet Gum loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Formosan Sweet Gum requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Formosan Sweet Gum will be sure to bring you many years of beauty and enjoyment.

Toxicity

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

Fertilizer

The Formosan Sweet Gum should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Region of origin

Formosan Sweet Gum’s native range is E. Asia - Central and southern China from Taiwan to south-west Sichuan.
