Hoya ‘Mayumi’ (UPT002) | 2-Inch

Hoya ‘Mayumi’ (UPT002) is the kind of Hoya that gives you something new to notice as it grows. Selected by Unsolicited Plant Talks from seedlings of the same seed pod, this collector Hoya combines striking venation, contrasting leaf margins, and foliage that can change considerably with light intensity.

It is also described by its originator as a rapid grower, making it especially rewarding if you enjoy watching a small rooted cutting develop into a substantial specimen. Your plant is a rooted cutting with new growth in a 2-inch pot.

Hoya ‘Mayumi’ (UPT002) Rooted Cutting Care & Details

• Origin: Hoya ‘Mayumi’ (UPT002) was selected and named by Unsolicited Plant Talks from a batch of seedlings produced by an open-pollinated Hoya ‘Noelle’. Because it was open-pollinated, ‘Noelle’ is the known seed parent, while the pollen parent is not identified. UPT named the selection after Mayumi, their Shiba Inu. Hoya ‘Noelle’ itself is an established cultivar originally selected in Hawaii and was published by Carol Noel in Asklepios in 2004. It has been described as a suspected Hoya vitellinoides × Hoya vitellina cross; additional cultivar history is available through the International Cultivar Registration Authority for Hoya.
• Leaves: UPT describes ‘Mayumi’ as having medium-sized leaves. One of its most appealing characteristics is how strongly the foliage responds to lighting: lower light produces deep, dark green leaves, while stronger light can bring out additional coloration. Mature examples also show prominent venation and contrasting dark margins, giving the foliage plenty of visual interest even when the plant is not flowering. UPT specifically notes that it can be grown under more direct light when stronger leaf coloration is desired.
• Growth Rate: This is a particularly appealing choice if you prefer Hoyas that visibly make progress. Unsolicited Plant Talks describes Hoya ‘Mayumi’ as a rapid grower, so under favorable conditions it can develop more quickly than many slower collector Hoyas.
• Watering: Water thoroughly while maintaining excellent drainage, then allow the growing medium to begin drying before watering again. How frequently that happens depends on your potting medium, temperature, humidity, light level, root system, and pot size. A small 2-inch pot can dry considerably faster than a mature plant in a larger container, so checking the plant rather than following a rigid calendar helps prevent both prolonged dryness and waterlogged roots.
• Light: Hoya ‘Mayumi’ offers some flexibility depending on the foliage you prefer. UPT reports that lower light produces deep, dark green leaves, while more intense or direct light brings out stronger coloration. For typical indoor growing, bright light is a good starting point; increase intensity gradually if you want to encourage its colorful response while watching for signs of stress.
• Temperature & Humidity: This plant is growing at approximately 85°F with 70–75% humidity. UPT describes ‘Mayumi’ as thriving in warm conditions and notes that it appears able to tolerate lower humidity as well, suggesting that very high humidity may not be essential once the plant is established.
• General Hoya Care: Give your rooted cutting good airflow, an airy and fast-draining growing medium, appropriate moisture, and sufficient light. Avoid leaving the roots continuously saturated, and remember that newly received Hoyas may need time to acclimate before making major changes to their growing conditions.
