Hoya carnosa 'Krinkle 8'

🌿 Hoya carnosa 'Krinkle 8' is a distinctive cultivar of the classic wax plant, belonging to the Apocynaceae family. Native to eastern Asia and Australia, Hoyas have adapted to climbing through forest canopies in their natural habitats. This particular variety stands out with its uniquely contorted leaves that look like they've been deliberately crumpled. It's considered a beginner to intermediate level plant, making it accessible for growers with some experience. Here's something interesting: the 'Krinkle 8' name comes from the number of concave dimples typically found on each leaf, though the count can vary slightly from leaf to leaf.
FOLIAGE AND GROWTH HABIT
This Hoya grows as a vining plant with semi-succulent stems that can trail or climb when given support. The thick, waxy leaves are deeply puckered and twisted, creating dramatic shadows and texture that change as light moves across them throughout the day. Leaf colour ranges from deep green to slightly lighter shades depending on light exposure, and the surface has a glossy, almost plastic-like finish. Each leaf feels firm and slightly rigid to the touch, with pronounced ridges and valleys that give the plant its signature crinkled appearance.
FLOWER DETAILS
The flowers emerge in rounded clusters called umbels, typically displaying pale pink to white star-shaped blooms with darker pink centers. They carry a sweet, honey-like fragrance that intensifies in the evening and can fill an entire room. The waxy, almost artificial-looking flowers have an undeniable charm that makes them worth the wait. Mature plants typically bloom once or twice per year, usually in spring through summer, though some specimens flower more frequently with proper care. To encourage flowering, provide bright indirect light, allow the plant to become slightly potbound, avoid moving it once flower buds form, maintain consistent watering during active growth, and give it a cooler rest period in winter with reduced watering.
CARE INSTRUCTIONS
🌞 Light: Bright indirect light works best, though it tolerates some direct morning sun. Aim for 6-8 hours of quality light daily for optimal growth and flowering.
💧 Water: Water thoroughly when the top half of soil feels dry, roughly every 7-10 days in summer and every 2-3 weeks in winter. Drench the soil until water drains freely, then allow it to dry between waterings. The bottom watering method works well for Hoyas.
🌡️ Humidity: Average home humidity of 40-60% is perfectly adequate, though it appreciates 60-70% when available.
🪴 Soil: A chunky, well-draining mix is essential. Combine regular potting soil with perlite, orchid bark, and a bit of coco coir for moisture retention without sogginess.
🏺 Potting: Use a pot with drainage holes, preferably terracotta or plastic, sized just slightly larger than the root ball. Hoyas prefer being snug in their pots. Repot only every 2-3 years or when severely rootbound.
🌱 Growth rate: Slow to moderate. Expect 3-6 inches of new growth in the first 6 months, potentially 12-18 inches in a year under ideal conditions. Mature vines can reach several feet in length over multiple years.
👩‍🌾 Fertilizing: Feed monthly during spring and summer with a balanced liquid fertilizer diluted to half strength. Some growers switch to a bloom-booster formula in early spring. Skip fertilizing in fall and winter.
🐾 Pet friendly: No. Hoya carnosa is considered toxic to cats and dogs if ingested. It contains compounds that can cause vomiting, diarrhea, and lethargy. Keep it out of reach of curious pets.
WHERE TO PUT IT
Hoya 'Krinkle 8' thrives in east or west-facing windows where it gets bright morning or afternoon light. It works beautifully on plant shelves, in hanging baskets near windows, or trained up a small trellis in a living room or bedroom. The bathroom can work if you have a bright window there, as the extra humidity helps. Avoid placing it in dark corners, north-facing rooms with limited light, or directly in hot southern sun for extended periods. Keep it away from heating vents and cold drafts near exterior doors in winter.
