'Yin' is the white margined form of 'Maize and Blue', for you Wolverine fans, and 'Yang' the reverse. Both are slow but beautiful, very heavily substanced blue plants. 'Yin' grows well but like many slow growing white centered hostas, 'Yang' may make a better pot plant. So buy 'Yin' and we'll throw in 'Yang' for free since you can not have one without the other. Lavender flowers in July and August. Good luck with them both!
