Salvia guaranitica (Anise-scented sage or Hummingbird sage) is a species of sage native to South America, including Brazil, Paraguay, Uruguay, and Argentina.
Description[edit | edit source]
It is a perennial or subshrub growing 1-3 m tall. The leaves are ovate, 4-13 cm long, mint green, and anise-scented when crushed. The inflorescences are up to 25 cm long, with each flower 3-5 cm long in varying shades of blue, with a dark basal calyx 10-12 mm long. Flowering begins in mid summer and continues through late autumn.
Salvia guaranitica is only a perennial in USDA Zones 7 to 10, but can be perennial in cooler climates, if planted in sunny microclimate.
Growing conditions[edit | edit source]
Deep, well-drained soils with adequate irrigation during drought periods. Water needs are low. In colder climates, the plant should be sited against a building or masonry.
Varieties[edit | edit source]
Numerous cultivars have been selected, including:
- 'Argentine Skies' (pale blue flowers)
- 'Black and Blue' (very dark violet blue calyx)
- 'Blue Enigma' (green calyx and blue flowers
- 'Blue Ensign' (large blue flowers)
- 'Purple Splendor' (large purple flowers)
Uses[edit | edit source]
Salvia guaranitica is a popular ornamental plant in mild areas where the temperature does not fall below −12 °C. It is most often planted in order to attract hummingbirds.
Maintenance[edit | edit source]
Prune to the ground in early spring, before new stems grow. Can be sheared to encourage bushiness. Staking is sometimes necessary. Excellent container plant.
Propagation[edit | edit source]
Division or stem cuttings. In colder climates, it can be dug in early autumn and kept indoors either in a pot or in vermiculite for dormant storage. It's hardiness can be greatly extended if planted against a building or masonry to maintain higher winter soil temperatures.
