No wildlife garden should be without it! This is a real bee magnet. with a gentle flowing form this is a great gap filling salvia to drift between other perennials or to edge borders. Let the flowers go to seed and it will gently self seed in the garden, filling any gaps, dont worry it's not thugish and is easy to thin if needed.
