Hoya carnosa are climbing houseplants used outdoors in mild climates. They have thick waxy, evergreen leaves and tight clusters of small and large flowers and are commonly grown in sunny windows. A hoya plant does best in rich, loose, well-drained soil and blooms best when pot bound; they are usually grown in containers even outdoors. Do not prune out flowering wood; new blossom clusters appear from stumps of old ones. Alternatively, if you're interested in another epiphyllum or some plumeria plants, we feature these products as well on our site.
