Botanical note: Hoya cv. 'Michelle' (also known as 'Michele', registration MB1255) is a horticultural hybrid cultivar bred by Mark Bernardo, named in honour of Italian botanist Michele Rodda.

Origin & characteristics

• Parentage: Hoya verticillata (from Laos) × variegated Hoya acuta (Hoya acuta albomarginata)
• Bred by: Mark Bernardo (registration MB1255)
• Growth habit: climbing vine, fast-growing, with vines reaching up to 2 metres, suited to climbing or trailing
• Leaf characteristics: large, thick, and glossy, deep green with prominently raised, network-like venation; some leaves carry silvery splash patterning; leaf colour deepens under medium light
• Flowering characteristics: white globe-shaped umbel clusters with a distinctive, memorable light fragrance; flower colour tends toward pink or creamy-white
• Growth rate: fast (more vigorous than most Hoyas)
• Pet safety: ✅ non-toxic to cats and dogs (though the sap is a latex substance and may cause skin irritation on contact — it's best to discourage pets from chewing it)

Light

• Ideal light: bright indirect light, around 10,000–20,000 lux
• Best placement: 1–2 metres from an east- or north-facing window, or a west-facing window filtered by a sheer curtain
• Notes:
• Avoid harsh afternoon direct sun — strong light combined with heat easily scorches the leaves
• A small amount of gentle morning direct sun, or filtered sunlight, is acceptable
• Leaf colour deepening and vein contrast becoming more pronounced under medium light is a normal response
• Maintaining a certain light intensity is needed to preserve the silvery markings

Watering

• Frequency: water once the soil is 60–80% dry, roughly every 7–10 days in summer, every 10–14 days in winter
• Method: water slowly around the rim until it drains completely from the base
• Signs of underwatering: slightly soft leaves, noticeably lighter pot weight
• Signs of overwatering: yellowing leaves, black water-stain spots (oedema)
• Seasonal adjustment: extend the watering interval further as growth slows in winter
• Important reminder: water once the soil surface is slightly dry, but avoid prolonged wetness; oedema spots are a cosmetic issue only and can be improved by reducing watering and increasing ventilation

Soil & pot

• Soil recipe:
• Recipe 1 (recommended): orchid mix or bark as a base + perlite + a little peat, lightweight and medium-grained
• Recipe 2: 1 part cactus soil + 1 part orchid mix + 1 part perlite
• Recipe 3 (advanced/semi-hydroponic): a semi-hydroponic system also works well for this cultivar
• Key point: must be well-draining and breathable while retaining slight moisture buffering — a bark-based mix is best
• Pot choice:
• Drainage holes are essential; plastic or terracotta both work
• Pair with a trellis, ring support, or moss pole to let the large leaves show off their veining in a climbing display
• A hanging basket also works, though a climbing display looks even better
• When to repot: every 2–3 years
• Repotting tip: size up by just one pot size each time (roughly 2 inches larger), avoiding an oversized pot that leads to standing water

Temperature & humidity

• Ideal temperature: 16–24°C (slightly warmer by day, slightly cooler at night is ideal)
• Minimum tolerance: 10°C, with cold damage risk below this
• Humidity requirement: 50–60% is ideal
• Ways to raise humidity:
• Adapts to typical household humidity, though higher humidity gives thicker, glossier leaves
• Use a humidifier, humidity tray, or place in a well-ventilated bathroom
• Flowering tips:
• Being slightly pot-bound helps trigger flowering
• Slightly cooler nights (around 15–18°C) combined with adequate light help stimulate bud formation
• A 4–5 week slightly drier rest period in winter can be beneficial

Common problems

How to explain to customers

"The Michelle Hoya is a relatively new hybrid cultivar that grows fast, with big, thick leaves and bold, raised veining that gives it real presence! It's a cross between verticillata and variegated acuta, so it's both attractive and easy to care for. Just remember to use a well-draining mix and keep it out of harsh midday sun. When it flowers, there's a distinctive fragrance, though you may need to wait for the plant to mature first. It's non-toxic to cats and dogs, though the sap is a latex substance, so it's best to discourage pets from chewing on it."

Fun facts

• The correct pronunciation of Michelle Hoya's name is "Mi-Kel-le" (the Italian pronunciation), honouring Italian Hoya expert Michele Rodda, though many people simply call it "Michelle."
• Its breeding registration number MB1255 represents breeder Mark Bernardo's 1,255th cultivar creation.
• One parent, Hoya verticillata, contributes its vigorous growth habit, while the variegated Hoya acuta parent brings the attractive silver marking genetics.
• Oedema spotting is a common "feature" of this cultivar rather than a disease — it's a cosmetic phenomenon caused by leaves absorbing water faster than they can transpire it.
