Gentiana sino ornata description

Beautiful ‘Gentian-blue’ trumpet flowers up to 5 cms in late summer and autumn. Stems are more lanky with not so many flowers as Gentiana Praecox.

How easy is it to grow:
This has won the RHS Award of Garden Merit [1]. To win this impressive accolade the plants must have outstanding excellence for decorating a garden, be robust, not require highly specialist growing conditions or care and not be particularly susceptible to any pest or disease.

Good for the front of a sunny or partly shaded border, hanging over a wall, in containers, or in an alpine bed or rock garden and requires acidic soil (ericaceous soil) that isn’t too dry. It is also happier in a humid atmosphere which means providing some shade in East Anglia and Southern Britain.

Sun in moister climates, or semi shade in dry areas.

What type of soil:

Requires acidic soil (ericaceous soil).

How much moisture:

Normal.

Hardiness and, or, lifespan:

Hardy, but will die if soil is alkaline or too dry.

Care and maintenance:

When newly planted always keep it watered until the roots have grown down and it is able to find its own moisture.

Size of plant:

Height 10 cm.
Spread 40 cm.

Planting density – to calculate how many plants are required in a planting scheme:

Allow 10 plants per square metre.

Buy alpines, herbs, wildflowers, perennials and ornamental grasses.
