My May Night Salvia has been in bloom since early spring, same as the Walker's Low Catmint Nepeta. I'll deadhead both as needed and they will bloom until we have a freeze. I've had several baby Catmint plants come up over the past few years that I've been able to move to another part of the yard or share with friends. Great plants and easy to grow. I live in East Texas where it's hot and humid in the summer. Hopefully, you can see my Catmint in this photo.
