One of the loveliest Salvia is S. Amante. It is a new colour break for S. guarantica and as you can see it is a fuschia pink. They do very well in the ground or indeed in pots, but if grown in a pot best to use John Innes No 3 as it is a soil based compost. They will also need feeding on a regular basis, you can use tomato food or long term feeds like Osmocote.
They flower from about mid May into autumn, and as I write this it is November and the plant is still flowering. They do however need some protection from frost.
