Salvia guaranitica 'Indigo'
Yet another form of S. guaranitica, this only grows to 4 ft. but it flowers from May until frost. Not as rampant as other forms of S. guaranitica, and seems to be frost-tender. It is possible that this might be the plant known as S. guaranitica 'Black and Blue' in the USA and Australia, whereas what has for some years been known as 'Black and Blue' in the UK...known as Salvia 'Costa Rican Blue' elsewhere, might be a separate species, flowering in late Autumn, this plant will be shown separately. The 'Indigo' form does not have tuberous roots, just to add to the confusion in this area, as all the guaraniticas I have grown are tuberous.
