Russian Sage : perovskia blue spire - seeds?

[CharnwoodFire]

Anyone know where I can get seeds for this blue spire plant, or do I need to buy it in pots (I would prefer to be cheap and buys seeds and grow them myself...?!)

Thank you! That's perfect! And it looks like a nicer smaller company than the likes of Sarah raven.
Think I'll add a few more things to my order too... This could be dangerous 😂
