Despite the name of Royal Hawaiian Purple, this hoya did not originate from Hawaii. As a matter of fact, no hoyas are native to the Islands of Hawaii but to the regions near the Philippines, Thailand, Papa New Guinea etc. On a trip to Hawaii a few years ago, I only found one plant vendor who had any knowledge of a hoya plant.
The pubicalyx ‘Royal Hawaiian Purple’ is widely known for its pretty dark purple flowers and long dark green leaves with splotches of grey. This is a fast grower evident in the photos below. This particular plant was started with four or five cuttings less than one year ago. Basically, I started the cuttings and when they were rooted I just forgot about the plant except for weekly waterings. This no special needs hoya is a must it you do not have time to hover over your plants to be sure they are healthy and happy.
