Hibiscus Clayi is endemic to Hawaii, but is listed as endangered. In the wild, it’s found only in a part of eastern Kauaʻi, but this one was growing at Hawai’i Tropical Bioreserve & Garden. For more information about Hawai’i Tropical Bioreserve & Garden, go to htbg.com.

It has a lot of company in that category, but at least these are being preserved in cultivation.
