Taiwania Taiwania cryptomerioides
ABOUT
Taiwania cryptomerioides, commonly known as Taiwania, is an evergreen conifer recognizable for its straight trunk and a pyramidal shape. The bark of Taiwania is reddish-brown and deeply furrowed, peeling off in long strips. Its branches are arranged in horizontal tiers, sweeping outwards and slightly drooping at the ends, giving the tree a graceful and dense appearance. The leaves of Taiwania are needle-like, small, and scale-like, covering the twigs densely. They are arranged in a spiral fashion and exhibit a dark green color that remains throughout the year. On the upper side of the leaves, there may be a white stomatal band which adds to the foliage's visual texture. Young trees have softer, more needle-like leaves, while older trees bear the characteristic scaled leaves. The cones of Taiwania are small and spherical, with a woody texture, and they bear seeds that are dispersed by the wind. Overall, the Taiwania carries a regal and enduring presence with its rich, evergreen foliage and classic conifer structure.

WaterThe Taiwania, or Coffin Tree, prefers consistently moist soil, so it's important to water it when the top inch of soil feels dry. Generally, this could mean watering it with about 1 to 2 gallons every week during the growing season, depending on the weather conditions and soil drainage. During the winter months, reduce watering to match the plant's slower growth rate and ensure the soil doesn't become waterlogged. It's vital to mimic the natural environment of the Coffin Tree by providing enough water to keep the soil moist but not saturated. Overwatering can lead to root rot, so always check the soil moisture before watering.
LightThe Coffin Tree thrives in full sun to partial shade conditions. It's best to place the tree in a spot where it can receive at least six hours of direct sunlight daily, but also has some protection from the intense midday sun, especially in hotter climates. A location that provides morning light with dappled afternoon shade is ideal for maintaining the health and vigor of the Coffin Tree.
TemperatureCoffin Trees are hardy and can tolerate a temperature range from 20 degrees to 85 degrees Fahrenheit. They prefer a cooler climate and can survive occasional drops below the lower limit but should be protected from prolonged exposure to extreme cold. The ideal temperature range for Coffin Trees is between 50 and 70 degrees Fahrenheit, providing a natural, comfortable environment for growth.
PruningPrune the Coffin Tree to remove dead or damaged branches, to maintain its shape, and encourage healthy growth. The best time for pruning is during its dormant season, usually in late winter or early spring before new growth starts. It should be pruned as needed, typically every two to three years, to avoid over-pruning which can stress the tree. Make clean cuts and avoid tearing the bark to maintain tree health.
CleaningNot needed
SoilTaiwania, or Coffin Tree, prefers acidic to neutral soil with a pH of 6.0 to 7.0. Ideal soil mix is a well-draining, fertile loam enriched with organic matter. A mix of two parts garden soil, one part peat moss, and one part perlite or coarse sand is recommended for optimal growth.
RepottingThe Coffin Tree should be repotted every 2 to 3 years to avoid becoming root-bound and to replenish its nutrients. Younger trees may need more frequent repotting, while mature trees can be repotted less often.
Humidity & MistingThe Coffin Tree thrives at high humidity levels, preferably between 70-80%. It is important to maintain this level of humidity for the health and growth of the tree.
Suitable locationsIndoor
Ensure bright, indirect light and high humidity.

Life cycleTaiwania cryptomerioides, commonly known as Taiwania, begins its life cycle as a seed, released from mature female cones, typically germinating in moist, shaded soil. Upon germination, a seedling emerges, gradually developing a root system and a straight stem with needle-like leaves. As a juvenile, the Taiwania exhibits rapid vertical growth and starts to develop its characteristic conical shape. Upon reaching maturity, which can take several decades, the tree begins to produce both male and female cones, with pollination typically occurring via wind dispersal. After successful fertilization, seeds develop within the female cones over a period of time before they mature and are eventually released to start a new generation. The Taiwania is a long-lived species, with individuals often reaching several hundred years of age, continuing the cycle of growth and reproduction throughout their lifespan.
PropogationPropogation time
Spring to Summer
Propogation: For Taiwania cryptomerioides, commonly known as Chinese Coffin Tree, the most popular method of propagation is by seed. The optimal time for sowing seeds is in the spring, once the threat of frost has passed and soil temperatures are conducive to germination. Seeds should be collected from cones that have dried and opened naturally on the tree. The collected seeds must be cleaned and can be sown directly into a well-draining soil mix. A light covering of soil, no more than a quarter-inch (about 6 millimeters), is ideal for covering the seeds. It is important to keep the soil consistently moist but not waterlogged. Under the right conditions, germination will occur within a few weeks, though it may be variable depending on environmental factors and seed viability.
