Blooms, and plenty of them: that's what both you and the butterflies want from a perennial, and that's what 'Blue Boa' agastache (sometimes called anise hyssop) will give you! This is quite simply one of the longest-blooming perennials you can plant, providing months - not mere weeks! - of nectar-filled blue flower spikes. Watch butterflies and other pollinators flock to it every day.

Agastache is a true sun-lover, and thrives in well-drained, even dry soil. It's the perfect way to transform a difficult spot into a butterfly oasis! This is a fairly large perennial that benefits from a good amount of space, but don't worry: it more than earns its keep in flower production and butterfly attraction.

initially smut/mold grew on leaves

While the plant is doing reasonably well, initially after planting it in the ground, the leaves had a dry powdery smut/mold and holes in the leaves. This seems to be improving now.

Free Blue Boa

I didn't order the Blue Boa. It was gifted to me to replace a plant that didn't survive. I love Hyssop but usually stick to the pink and orange colors so I didn't think I would love the Blue. Turns out that I do love it! The color pops and is beautiful!
