Hoya Carnosa 'Tricolor', also called wax plant, is a vining houseplant in the Apocynaceae family native to East Asia and Australia, where it climbs through humid tropical forests. It has a devoted following among collectors and everyday plant lovers.
The leaves are thick and waxy with creamy white edges and rosy pink flush surrounding a deep green center, intensifying in brighter light. Long vines trail from a hanging basket or cascade off a high shelf, and the foliage feels almost porcelain-smooth to the touch.
Hoya Carnosa Tricolor produces star-shaped flower clusters called umbels in waxy pale pink to white, carrying a light, sweet fragrance most noticeable in the evening. Blooms appear most reliably in spring and summer when it receives bright indirect light and experiences a slight drop in nighttime temperatures. The same flower clusters can rebloom from the same spur year after year, so never remove spent peduncles after flowering.
It is pet-friendly and safe for cats and dogs. The plant purifies indoor air by filtering formaldehyde and other common toxins. You can leave it up to ten days without water. Rotate the pot every few weeks for even growth, and keep it away from AC vents and heating units that blow dry air directly onto the leaves. Move it outside in summer to a warm, shaded spot, keeping it covered from heavy rain and away from intense direct sun.

Hoya Carnosa 'Tricolor' grows well in bright indirect light and tolerates medium light, but scorches in south-facing windows with direct afternoon sun.
Water it every 10 to 14 days in spring and summer, and reduce to once every 3 to 4 weeks in winter.
Hoya Carnosa Tricolor does best in a chunky, fast-draining mix of perlite, orchid bark, and potting soil in roughly equal parts.
It prefers temperatures between 60 and 85°F and should be protected from temperatures below 50°F.

A: It is non-toxic and safe for both cats and dogs.
Q: What window placement works best for bright indirect light?
A: Hoya Carnosa 'Tricolor' does well in an east or north-facing window, or a few feet back from a west-facing window where afternoon rays don't hit the leaves directly.
Q: How do I propagate Hoya Carnosa Tricolor?
A: Take a stem cutting with at least one node and one or two leaves, then root it in water, moist sphagnum moss, or a light perlite mix. Roots typically appear within 3 to 6 weeks in warm, humid conditions.
Q: Can I grow this plant outdoors year-round?
A: Hoya Carnosa Tricolor grows outdoors only in USDA zones 10 to 11, which cover the warmest parts of Florida, California, Hawaii, and southern Texas and Arizona. Elsewhere, move it indoors before temperatures drop below 50°F.
Q: Why is Hoya Carnosa Tricolor not blooming?
A: Ensure it receives bright indirect light and experiences a slight drop in nighttime temperatures. Do not remove old flower spurs, since new blooms emerge from the same spot each season.
Q: Can I leave this plant unwatered for a trip?
A: Hoya Carnosa Tricolor can tolerate up to ten days without water. In winter, when watering frequency drops to every 3 to 4 weeks, longer absences are possible.
