Snake Tree (Radermachera sinica)

There are plants that have common names that can even be repellent, but when you discover what is behind them, when you see the beauty of those species, it may happen that you want to have them in your home or garden. This is what usually happens with the snake tree.

Although it is not resistant to cold, it is often cultivated as a houseplant since it adapts quite well to those conditions, although it must be taken into account that it can easily exceed six meters in height.

Origin and characteristics

Our protagonist is an evergreen tree, that is, it remains evergreen although its leaves fall as new ones sprout, native to China, Taiwan, Bhutan, India, Burma and Vietnam. Its scientific name is Radermachera sinica, and it is popularly known as snake tree, snake tree or radermachera.

In habitat it reaches 30 meters in height, but when cultivated it does not usually exceed 8 meters. Its trunk can thicken up to one meter in diameter. The crown is wide, almost parasolate, formed by bi or tripinnate leaves 20 to 70cm long and 15-25cm wide, opposite, whole and petiolate, of a glossy dark green color.

The flowers are grouped in terminal or lateral panicles, yellow, with the bell-shaped calyx measuring about 7cm in length. The fruit is a dehiscent capsule that finishes maturing towards autumn.

If you want to have a copy, we recommend you provide the following care:


It is important when you are going to buy a plant or seeds to know if it can live well in the climate that exists in the area, since otherwise you will have to grow it indoors… or choose another. In the case of the snake tree, although it might be thought that it is suitable for those with temperate temperatures (not in vain, in China for example it is normal that there are frosts in many parts of the country every year), the reality is that it is a tropical species.

This means that to be able to grow outdoors it is necessary that the temperature be kept above, at least, 5ºC, and even if they are 18ºC better. Now if it goes down to 0 degrees it will resist it, but it may lose some leaves.


  • Pot: uses universal growing medium (on sale here ).
  • Garden: grows in fertile soils, with good drainage.


It is a tree that needs frequent watering, especially in summer when the environment is drier and warmer. In winter, however, it will be necessary to try not to give it too much water, since the substrate or soil will take longer to dry and, in addition, the growth rate is slower so it does not need as much.

So that there are no problems, I advise checking the soil moisture before watering, either with a digital moisture meter (on sale here ) or with the classic analog method, that is, inserting the wooden stick (if it comes out with a lot of soil attached, there is no need to water).

Even so, when in doubt you should know that, on average, it needs about 3 irrigations a week in summer, and 1-2/ week the rest of the year. If you have it in a pot, you can put a plate under it, but you have to remember to remove any excess water 20 minutes after watering.


Water is as important as the regular supply of fertilizer. From early spring to late summer (you can until early fall if you live in a mild climate or without frost) you should compost it with mulch, compost, or other organic products. You just have to bear in mind that if you have it in a pot, you must use liquid fertilizers, like this one sold here, following the instructions specified on the container.

You can also use chemical fertilizers, but taking into account their risk of toxicity, both for the environment and for humans, they are not highly recommended.


The snake tree multiplies by seeds in spring and by cuttings in summer. Let’s see how to proceed in each case:


In order for them to germinate, you must sow them in a seedbed (like this tray that they sell here ), fill it with universal cultivation substrate, and put a maximum of 2 seeds in each alveolus or pot. Then, water, and place it outside, in semi-shade.

If all goes well, they will germinate in about 15 days.


In early or late summer, cut a branch about 30-35cm in length, impregnate the base with homemade rooters and plant it in a pot with vermiculite previously watered.

Placing the pot outside, in semi-shade, it will emit its own roots after about a month.


You don’t really need it, but it is advisable to remove dry, diseased, or weak branches in late winter.

Planting or transplanting time

In spring.


It resists up to 0 degrees, but prefers warm tropical climates.
