Salvia flava, as we have found at sales, is usually mislabelled as bulleyana. The flowers are quite different. Bulleyana is a purple flower, flava is yellow…
Some species will tolerate only light frosts, but some of the perennials are more frost-hardy. They will grow well when planted in full sun in well drained light soil with adequate watering in the summer. Cut back in spring.
Propagate shrubs and sub-shrubs by softwood, semi-ripe or basal cuttings in mid-summer. Sow seed of half hardy annuals under glass in early spring and of fully hardy species outdoors in mid-spring. You can propagate perennials by division in the spring.
