This rare and very beautiful yellow salvia is one of my absolute favourite perennials. Best in semi-shade, it sends up very sturdy stems to around 1.5-2m and these are topped with beautiful pale yellow salvia flowers from late autumn and last well into winter. Loved by waxeyes. Semi-evergreen. Frost tender so best planted with some shelter from trees or shrubs. Foliage has a lovely lemony scent too.
