Jiaogulan comes from far away. Does the plant only have beauty or also winter hardiness in its baggage? If you have it as a houseplant in your home all year round, the question is not so crucial. But out in the open, answering them is essential for survival.

The immortality herb is very hardy, but loses all of its leaves in frost

Only conditionally hardy

Jiaogulan is a perennial climbing plant that we can keep outside all year round. But when staying outdoors in winter, it is important to know the limits of what is bearable. With this Asian herb it is around -15 °C. Since the thermometer can sink lower in this country, Jiaogulan is only partially hardy.

Plant out in mild regions

In mild regions of our country, the chances are good that the herb of immortality will survive in the garden for many years. Nevertheless, give it a sheltered place when planting. Covering the base of the roots with brushwood or leaves also contributes to safe overwintering.

Tendrils and foliage die off

Don't be alarmed when the leaves begin to wither in the fall. This process is typical for all specimens that have a permanent outdoor location. Of them, only the rhizome buried in the ground will overwinter. Leave the dried tendrils on until spring, as they are a natural protection against the cold.

If you don't trust the winter or live in a harsh area, cultivation in a large container is a good idea. The herb can breathe fresh air in it from spring to autumn. If it gets cooler, a move has to take place:

  • needs a bright place
  • can continue to grow at 15 to 20 °C
  • e.g. B. in the conservatory
  • the plant then retains its foliage
  • it remains evergreen and decorative

If the available winter quarters are dark, the plant can still overwinter there. You should Jiaogulan in this case up to about 10 cm. cut back.

Winter hardiness is irrelevant for indoor plants

You can also cultivate Jiaogulan exclusively indoors. The long tendrils are particularly effective in hanging plants. Winter hardiness is irrelevant in the room. But please bear in mind that the warmer a plant is in winter, the more care it requires of you.
