What is Monstera ‘Burle Marx Flame’?
Monstera ‘Burle Marx Flame’ is one of the most coveted collector aroids on the market — a climbing Monstera cultivar named for its extraordinary leaf shape and the vivid reddish-orange flush that new foliage displays as it unfurls. Where a standard Monstera deliciosa produces broad, heart-shaped leaves with oval fenestrations, the ‘Burle Marx Flame’ develops long, deeply pinnate lobes that fan out like the blade of a flame, giving mature specimens a sculptural, almost architectural presence.
It belongs to the same family as its better-known relatives — Araceae — and shares their tropical origins, preferring warmth, humidity, and indirect light. As a climbing Monstera, it produces aerial roots and benefits from a sturdy moss pole, which encourages the plant to push out larger, more deeply lobed leaves as it matures.
What makes the ‘Burle Marx Flame’ leaf shape so unusual?
The defining feature of this cultivar is its deeply pinnate leaf structure. Instead of the familiar oval holes (fenestrations) of Monstera deliciosa, the ‘Burle Marx Flame’ cuts its leaf blade all the way to the midrib, creating distinct, elongated segments arranged like feathers. In bright, indirect light with a vertical support, mature leaves can reach striking proportions with four or more pairs of lobes per side.
The fiery reddish-orange coloration of new leaves — the “flame” — fades as the leaf hardens off to a deep, glossy green, but the brief display when a new leaf unfurls is one of the most dramatic moments in aroid collecting.
How much light does Monstera ‘Burle Marx Flame’ need?
Bright, indirect light is the sweet spot. An east- or west-facing window, or a few feet back from a south-facing window filtered by a sheer curtain, works well. More light means faster growth and more pronounced pinnation in new leaves. Avoid direct afternoon sun — the leaf tissue is thinner than a standard Monstera and scorches more readily. In low light, leaves emerge smaller, less lobed, and the fiery flush on new growth is muted.
How do you water and feed Monstera ‘Burle Marx Flame’?
Water every 1–2 weeks, letting the top 1–2 inches of the potting mix dry before the next drink. This cultivar shares the aroid family’s intolerance of waterlogged roots, so a chunky mix — coarse perlite, orchid bark, and a small amount of peat or coco coir — is strongly recommended over standard potting soil. During the growing season (spring through early autumn), a balanced liquid fertilizer diluted to half-strength every 3–4 weeks supports the slow but steady growth rate.
Humidity above 60% keeps the large leaves looking their best; brown crispy margins are almost always a sign of dry air rather than a watering problem.
Does Monstera ‘Burle Marx Flame’ need a moss pole?
Yes — and this is one of the most impactful things you can do for the plant. Like all climbing Monstera, the ‘Burle Marx Flame’ produces aerial roots that anchor it to trees in the wild. Indoors, a moss pole, coco coir totem, or wooden plank gives those roots something to grip. The plant responds by pushing out noticeably larger and more deeply pinnate leaves, accelerating the development of the mature form that collectors prize. Without support, leaves stay smaller and growth remains more compact.
Is Monstera ‘Burle Marx Flame’ toxic to pets?
Yes — as a Monstera, the ASPCA lists the genus as toxic to cats and dogs. The insoluble calcium oxalates embedded in the plant’s tissue cause oral irritation, excessive drooling, and vomiting if chewed. Given that this is also an expensive and difficult-to-replace collector plant, keeping it out of reach of curious pets is doubly worthwhile.
