The genus Salvia includes a number of species, among them the herbs sage and clary. S. splendens, a perennial grown as an annual, is an established favourite in summer bedding schemes, especially of the formal type. Its dense spikes of true scarlet flowers last into early autumn. Modern varieties include pink, purple and white-flowering forms.
PROPAGATION Sow seeds in pans in early spring at 18°C/64°F and prick the seedlings out into boxes when they arc large enough to handle. Harden off in a cold frame before planting out in late spring.
GROWING Salvias need a warm, open, sunny site on moderately rich, free-draining soil. Do not let them dry out in hot weather. Remove faded flowerheads regularly.
VARIETIES `Blaze of Fire', `Tetra Scarlet', both early flowering; `Tom Thumb', only 20cm/8in high, red or white; `Dress Parade', all colours.
POSSIBLE PROBLEMS Low temperatures inhibit growth, causing stunted plants and yellowing leaves.
