This is a very dark purple Salvia which I planted last year in front of a giant orange sun loving Bromeliad Aechmea blanchetiana. I am hoping for a good colour contrast when 'Amistad reaches the 2 metres it is said to. So far it is a well behaved small shrub with bright green foliage and masses of flowers. No damage to the branches from nectar feeding birds either.
The story goes that this plant was found in a market in Argentina and released to the garden scene in Australia in 2013. Plant Breeders Rights apply to this plant.
