PLANT ARCHIVE | Salvia longispicata x farinacea ‘Mystic Spires’

Salvia longispicata x farinacea ‘Mystic Spires,’ a member of the sage family, presents as a vertical accent plant, adorned with captivating purple-blue spires that bloom from late spring through late autumn.

Salvias grow in most parts of the world but are believed to originate from the Americas, Europe, and Asia. While Salvias are recognised in Australia as robust, hardy plants for warmer climates, they are not native to Australia.

The ‘mystic spires’ species is a more compact hybrid derived from its larger cousin, ‘Indigo spires’. Reaching approximately 70cm tall x 70cm wide at maturity, Salvia mystic spires are a heat tolerant variety suitable for most Australian gardens.

Growing conditions

Thriving in heat, Salvia longispicata x farinacea performs best when planted in full sun and spaced 1m apart. This species adapts to most soils and once established, is drought tolerant only requiring additional watering in very dry periods.

Care and maintenance

Regularly remove spent flowers to encourage repeat flowering. Once flowering is finished, prune back to half its size to retain a compact growth habit. A heavier prune may be required if it becomes untidy. Apply a slow-release fertiliser once every Spring.

Garden design

Salvia mystic spires are a delightful addition to perennial-style gardens. They create a charming border, adding vibrant pops of colour when planted in clusters, as showcased in our Malvern garden. Mystic spires shine beautifully when incorporated into a colour palette of purples and pinks and serve as a magnet for birds and bees, making them an excellent choice for garden enthusiasts.
