Mood Indigo: Salvia 'Indigo Spires'

Salvia 'Indigo Spires' with Mauritius Hemp (Furcraea foetida var. mediopicta)

Salvia 'Indigo Spires' with Yucca elephantipes ' Silver Star'

I like to grow this Salvia amongst my spiky plants as the long dark infloresences weave their way through the stiff upright stems for most of the year and make a great contrast against lighter coloured foliage. This is a hybrid between Salvia longispicata and Salvia farinacea and was discovered as a chance seedling at the Huntington Botanic Gardens in 1979.It needs no other care than a light prune at the end of winter and it is back to flowering non-stop.
2017 update: I am currently out of stock of this Salvia.
