Salvia Costa Rica Blue
This amazing salvia flowers for almost the whole year, except for mid-summer, so it starts its long period of bloom at the end of late summer and continues till December, when it has its rest. It is a more manageable size than most of the other large shrubby salvias, but is still tall (ht 2-2.5m). It has big, rich blue flowers with dark calyces, which make them look very striking. The colour of the flowers really goes with almost anything in the garden. I like it with rich cerise and bright pink flowers, including other salvias, cannas (such as Canna iridiflora) and camellias, and it is effective with silver, purple or golden/lime foliage. It also looks stunning with hot colours, such as orange, red and yellow flowers, or autumn leaves. It tends to sprawl a bit and probably needs to be staked, but can be chopped back at any time of the year and will still go on producing flowers. Regular removal of one woody stem will enable it to almost continually flower, apart from its rest from December to February, which is the best time to prune it hard. It is best in a sunny spot but will flower reasonably well with a little shade.
Flowers in March, April, May, June, July, August, September, October, November.
