Description

Sedum rupestre Boundary Blue description

Silvery-blue foliage looking really spectacular in colder weather.

Nowhere as aggressive as its cousin ‘Angelina’.

Yellow flowers on tall stems in the summer.

A pollinator friendly plant including bees.
This is a butterfly friendly plant.
Can tolerate a coastal aspect with a certain amount of salt laden air.

How easy is it to grow:
Good for the front of a border or on a bank, or patio and is easy in most soils, including heavy or clay ones provided there are no Vine Weevil in your garden (see ‘Care and maintenance’ below).

Buy alpines with confidence because we tell you the truth about them.

Common name: Boundary Blue Stonecrop.

 

The best position in the garden:

Prefers sun.

Is it useful as a ground cover plant?

Yes, it will fill a space at the front of a flower border.

What type of soil:

Any reasonable soil, also tolerates chalky soil and tolerates clay soil.

How much moisture:

Normal or dryish stony.

Hardiness and, or, lifespan:

Hardy.

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.
It is susceptible to Vine Weevil which lay their eggs by the plant and these develop into white, banana shaped grubs that chomp the roots. Biological control is pretty good at controlling it.

Height 20 cm.
Spread 40 cm.

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

Allow 5 plants per square metre.
