Masdevallia Heathii is a standout hybrid between Masdevallia ignea and Masdevallia veitchiana, combining the best traits of both parents into a compact, floriferous plant. Its flowers are bold and bright—typically brilliant orange to fiery red—with subtle veining and dramatic tails that extend from the triangular bloom. The effect is like a flame suspended on slender stems.
Unlike many Masdevallia species, Heathii is known for being relatively forgiving and generously blooms when given consistent care, making it an excellent choice for intermediate growers looking to branch into cooler-growing orchids.
Light: Bright, indirect light. Avoid harsh direct sun.
Temperature: Cool to intermediate (50–75°F). Tolerates a bit more warmth than some Masdevallias.
Humidity: 60–90% with steady air circulation.
Water: Keep evenly moist, especially during active growth. Never let the medium dry out completely.
Potting mix: Moisture-retentive mix such as fine bark and sphagnum moss.
Fertilizer: Use a balanced orchid fertilizer at ¼ strength every 2–4 weeks during the growing season.
How to grow Masdevallia Heathii indoors:
This hybrid adapts well to indoor environments as long as humidity and air movement are maintained. A north- or east-facing windowsill, a humidifier, and a fan for airflow will help it thrive. Terrariums or orchidariums are also excellent setups. Use distilled, reverse-osmosis, or rainwater for best results—unless your tap water is from a pure source such as San Francisco’s Hetch Hetchy system, which is generally safe.
How to grow Masdevallia Heathii outdoors in the Bay Area:
Outdoors, this hybrid can be grown successfully in cool, humid microclimates like those in Daly City, Pacifica, or the higher elevations of the East Bay. Place it in bright shade with good protection from afternoon sun and drying winds. A covered lath house, shaded patio, or well-ventilated greenhouse is ideal. Keep moist year-round, especially during heat spells
Bloom season: Most often spring and fall, but may bloom intermittently year-round
Pet safe: Yes
Difficulty: Intermediate. More tolerant than many Masdevallias but still prefers cool, moist conditions.
