Salvia corrugata
Salvia corrugata

We first came across Salvia corrugata while visiting a garden in Kew. Immediately attracted by the brilliant blue flowers, on a closer look the leathery foliage also attracted us. 

Said to be relatively new in cultivation, it has only been around since the early 1990s, however with the attractive flowers it has become a garden favourite.

From Peru and Columbia, this is a plant that thrives in cooler climates as is grows naturally high in the mountains.

It gets the name ‘corrugata’ from the texture of the leaves which are heavily ribbed. It is the flowers that are main attraction, appearing in whorls of a very attractive blue. Sometimes also called the ‘Ribbed Sage’.

The flowers attract bees and birds to the garden.

Planting Instructions

  1. Choose a sunny position.
  2. Humus rich soil, add some well rotted compost if needed.
  3. Dig a hole larger than the container, this loosens the soil and allows for faster root development.
  4. Plant back fill and firm in well.
  5. Stake in windy positions.
  6. Water in well with a liquid seaweed fertiliser.
  7. Mulch to maintain a cool root run.
  8. Fertilise in spring with a general purpose slow release type fertiliser.
