Growing in zone 9b/10 near the Gulf of Mexico in Central Florida. I cut it back every winter and each summer it comes back larger and fuller. Easy to grow plant and beautiful blooms through the summer. The leaves are fuzzy and fragrant when you touch them. Grows in full Florida sun with no problem. No bugs seem to mess with it at all. Easy care plant!

this plant can be easily grown from seed. the seeds look like peppercorns. using peat pellets in addition to outdoor sowing, two seedlings appeared 6 days after planting (one in a peat pellet and one outside). i soaked the seeds in warm water for 24+ hours prior to planting.

It does go dormant in my zone 9a but it returns in the spring without issue, so I think it deserves better than a zone 10 +
