Gentian perennial and gentian tree do not have much in common apart from the name. While the gentian (Gentiana) is a perennial native to the Alps, the gentian tree (Solanum), also known as the potato tree, is native to South America. They only have blue flowers.

The gentian perennial thrives in the mountains, in the garden and even as a pot plant

Preferred location

Gentian species are vicarious. This means that they cannot be planted together as they have different demands on the site.

Clusius gentian, for example, requires very calcareous soil. Koch's gentian, on the other hand, does not like lime at all, it needs acidic soil.

What all gentian species have in common is that they prefer semi-shady to sunny locations. In nature, they usually grow under taller plants because they only tolerate direct sun for a short time. The soil must be loose and able to drain water well.

maintenance of the perennial

Gentian needs less water in summer than in winter. The roots should never dry out completely. Care includes:

  • Water regularly
  • Avoid waterlogging
  • Add lime or humus if necessary
  • Cut before winter
  • If necessary, cut back after flowering

Propagating Blue Gentian

Like almost all perennials, gentian is quite easy to propagate. Most often, new plants are sown. As cold germs, however, the seeds have to go through a longer cold phase before they germinate.

Propagation by division is also a good solution for perennials. To do this, the plants are taken out of the ground, divided in the middle and then reinserted or transplanted.

Gentian perennials are not very long-lived. They can be rejuvenated by division and maintained longer in the garden or in pots.

Bring gentian perennials over the winter

Basically, gentian perennials are hardy. In rough locations, you should still provide winter protection. Covering the Koch gentian with brushwood or fir branches is sufficient.

Pot gentians should be overwintered in a sheltered spot on the patio or balcony, but never indoors. To be on the safe side, the pot is placed on styrofoam and covered with protective film.

tips and tricks

In contrast to the blue or yellow gentian, the gentian tree is very poisonous in all parts of the plant. You can therefore easily care for the alpine flower in the garden, while you should only keep a gentian bush if there are no children or animals in the family.
