A mix of hardy herbaceous and borderline hardy sub-shrubby ones. We just grow the ones we like and grow well for us!
Salvia is another very large genus where it would be impossible to grow all of them due to the numbers and the varied conditions they require. We have a small selection, mostly of hardy herbaceous types, that have proved to be well worth growing over the years.
The herbaceous types are mostly forms of the British native Meadow Sage or Meadow Clary, Salvia pratensis, the hybrids of Salvia nemorosa and some selections of Salvia verticillata. These are all good garden plants that will thrive in ordinary soil in sun with reasonable drainage, the drainage is key - a waterlogged site in winter will cause losses. These Salvias all start flowering in late spring and will continue through most of the summer and into autumn, and provide a good winter seedhead from many of them too.
The less hardy types include forms of the shrubby Salvia microphylla and Salvia x jamensis (central Americans) and the south American Salvia guaranitica and Salvia uliginosa. These will usually all be hardy in sheltered gardens, especially if planted with a mulch of composted bark or similar around them. Many people like to grow them in pots and containers though and these will need the protection of a cold greenhouse or similar in winter.
Stunning sky blue flowers from spring to autumn on this modern S. chamelaeagnea hybrid from New Zealand. Scented foliage is a bright, fresh green. 60cm in a sunny spot with good, drained soil. Probably not fully hardy.
TENDER An eyecatching hybrid with masses of racemes of purple calyces and white flowers flushed with pale lavender. May be worth trying outside in a warm sunny, sheltered garden but overwinter frost free to be safe. 50cm.
HALF-HARDY. Woody based herbaceous sage with big matt green leaves and spires of orange-red furry flowers to 1.8m from midsummer to autumn. Overwinter as cuttings or grow in a big pot and keep frost-free.
AGM An excellent clear blue form producing many spikes of flowers from May until midsummer and then sporadically later. Can be cut back after the first flush to promote more. Drained soil in sun. 40cm.
