I grow this as an annual in Seattle, in full sun, good soil, moderate water. It spreads and blooms more and more profusely from July into fall, until a hard frost kills it. Hummingbirds visit it. Not super showy but the color is divine.

Uncharacteristically for salvias, this beautiful plant forms a tuber that can be dug and stored over the winter in colder climates like mine. I've had great luck growing this here in full sun in humusy soil or in pots. I've seen others here growing it in large hanging baskets too - beautiful! What a gorgeous plant this is, with flowers the color of the bluest blue sky you can imagine.

This salvia isn't evergreen in my zone 8b garden.
It dies down to the ground after our first really good frost. But it has reliably come back up each spring, though it's a later showing than some.
Super easy plant to grow from seed.

Grows well in full sun in thick clay, but won't overwinter in the UK there. You'll need to stop snails devouring the small plants - I find it easier to start them in pots until they're a couple of feet high. But they're absolutely fantastic - such an intense dark blue.

Only 1 month old from 1-gallon can but already has grown a third larger. Incredible clear blue flowers really stand out, adds lovely vertical accent as well. Probably likes warmth (No.Cal. just started its 'summer' heat in Sept.), a weekly watering and good drainage (like all sages). Got a second one and hope it will do as well as the first. Will keep posted on how well it does through our rainy winter. It is an evergreen, leaves are a clear green color.
