Pineapple and tangerine sage are both names for Salvia elegans. I agree, lovely scent, but neither pineapple nor tangerine to my nose.
I looed up S. 'Amistad', that looks very nice, haven't seen it for real though.
I shall have to have another sniff, next year it will have to be. I can't keep it through most winters (just occasionally comes through) and I didn't have any this year. But they both seem to be Salvia elegans so maybe it's like the colour varaitions in Salvia microphylla - all one species but different cultivars.
I must get some more next year though, I've missed it being about.
Roll on indeed, bound to be a better one next year.
Though I do love the winter shake up and restylings and looking out for the first bulbs.
S. Amistad looks a real beauty, I take it this is a new variety that should be around next year?
