About Hoya Deykeae

Hoya deykeae · also called Deyke's hoya · houseplant

Hoya deykeae is a sought-after Bornean wax plant prized for large, fuzzy leaves with bold silvery splash patterning and clusters of pale fragrant flowers. A moderately vigorous climber, it wants bright indirect light, warmth, high humidity, and a very airy epiphyte mix. Let it dry between waterings and it rewards careful growers with striking foliage.

Preferred mix: Very airy, fast-draining epiphyte mix

Watch for — Root rot in dense or wet mix: The fine roots demand air and dry quickly; use a very chunky medium and let it dry between waterings to avoid rot.
