Hoya's 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.
