Horticultural guidance

Care information is general guidance compiled from institutional and botanical sources. Most hoya species have no published species-specific care instructions; where that is the case, profiles say so and apply genus-level guidance. Results depend on your climate, home and plant.

Pet safety

Pet toxicity notes report only what the ASPCA's Toxic and Non-Toxic Plants list states. A species that ASPCA does not list is shown as "not listed", which means no information, not "safe". A non-toxic listing does not mean a plant cannot cause stomach upset if eaten. If an animal may have eaten a plant, contact a veterinarian or an animal poison control service. This site does not give veterinary or medical advice.

Identification

The Hoya Identifier narrows possibilities using recorded traits; it cannot confirm an identification. Many hoyas look alike, leaf traits vary with light and age, and many plants in the trade are hybrids or carry incorrect labels. Flowers and, for difficult cases, specialist examination are needed for a confident identification.

Taxonomy

Names follow the World Checklist of Vascular Plants (Royal Botanic Gardens, Kew) as retrieved on the date shown on each profile. Classifications change; other checklists or societies may use different names.
