A different juvenile form
Early leaves may be entire or show very few splits. Their simpler shape is a normal stage, rather than the mature appearance of the selection.

The relationship grows, one leaf at a time 💚

Monstera ‘Burle Marx Flame’ has an unusual outline that stands apart among monsteras: its young leaves are narrow, elongated and substantial, with deep green colour and an almost leathery texture. As the plant matures, new leaves can develop deep splits and slender, extended lobes that resemble flames.
This changing form adds something to your collection that develops alongside it. The clean, upright presence of a young plant gradually becomes a more intricate silhouette, with open spaces between the lobes. It is a monstera for anyone who enjoys today’s leaf as much as the anticipation of the next.
Its distinctive shape is linked to the maturity of the plant and the development of each new leaf.
Early leaves may be entire or show very few splits. Their simpler shape is a normal stage, rather than the mature appearance of the selection.
With more mature growth, splits extend deeply into the blade, leaving long, narrow lobes. The result is more open and linear than the familiar monstera outline.
It grows slowly and develops a stem that benefits from support. Its form changes over time, without each leaf following a fixed schedule.
Why you’ll love it: each new leaf adds a small chapter to its transformation.
A young plant looks at home on a side table or stand near a bright window with indirect light. As it grows taller, allow space for a sturdy support and move it to a lower stand if needed. A quiet background makes the leaf outlines easier to appreciate.
Combine its narrow outline with broader or finer foliage, in separate pots with similar indirect light.
Plenty of bright, indirect light. Filter strong sunlight.
Water when the upper mix dries and the pot feels lighter. Drain well.
Steady warmth, around 18–27°C. Usually adapts to moderate air humidity.
Unsafe to chew. Keep away from pets and young children.
Provide plenty of indirect light for steady growth. A bright window with a sheer curtain works well where sunlight is strong. A dark position can lead to a sparse stem and slower development of the leaves.
Water once the upper mix has dried, around 2–3 cm in this small pot, and the pot feels lighter. Moisten evenly and let it drain. Do not leave water in the outer planter or wait for the entire mix to become completely dry.
It usually adapts to ordinary moderate humidity, around 40–60%. Avoid drying air from heating or air-conditioning. If a new leaf takes time to unfurl, do not pull it open.
Maintain steady warmth, around 18–27°C, without abrupt changes. Cold combined with wet compost is particularly hard on the roots. Protect against draughts and contact with cold glass.
Use an airy aroid mix, such as Sybasoil Aroid Premium Mix, and a pot with drainage holes. Add a sturdy support when the stem needs it, fastening the stem loosely and keeping the leaf stalks free.
Feed during active growth according to the label, taking account of nutrients already present in the recommended mix. Excess fertiliser does not correct naturally slow growth. Repot when roots fill the container, moving up only one size.
The story of ‘Burle Marx Flame’ is connected with the garden of Brazilian landscape designer Roberto Burle Marx. This unusual monstera, with its narrow, deeply divided mature foliage, was found among the plants in his collection.
‘Burle Marx’ recalls the collection associated with the plant, while ‘Flame’ evokes the elongated lobes of mature leaves. This distinctive form entered cultivation under that name.
The plant’s original provenance was not recorded before Burle Marx’s death. It remains unclear whether it is a separate species, a hybrid or a mutation of Monstera deliciosa. The Brazilian garden belongs to its history without establishing its native geographical origin.
Heteroblasty is the production of different leaf forms as a shoot matures. Deeper splits appear in newly developing leaves; an already developed juvenile leaf does not later turn into a mature, divided leaf.
Aerial roots are adventitious roots, formed on the stem rather than as extensions of the original root. In climbing monsteras they help with attachment and can take up water when they reach suitable moist material.
A node bears an axillary bud, with meristematic tissue capable of producing a new shoot. This is why a cutting needs a viable node; a leaf with its stalk alone does not have the same regeneration mechanism.
Monsteras, like many aroids, contain insoluble calcium oxalate crystals in specialised cells. Needle-shaped raphides contribute to tissue defence and explain the irritation caused by chewing the leaves.
Answers about its form, growth and common signs to watch for.
Juvenile leaves have a simpler shape. The characteristic deep splits are associated with more mature growth and sufficient light. Not every leaf develops the same degree of complexity.
Not in their basic shape. A fully developed leaf will not later acquire the splits of a mature leaf. Watch the form of subsequent leaves instead.
Not particularly. It is slow-growing and may leave long intervals between new leaves. Steady light, healthy roots and time matter more than extra fertiliser.
When the stem begins to lengthen and lean. Add a sturdy support without damaging the roots and fasten the stem loosely, leaving the leaf stalks free.
Its precise relationship remains unresolved. The name Monstera ‘Burle Marx Flame’ therefore identifies the cultivated selection without assigning it to a particular species.
Not for chewing or swallowing. Like other monsteras, it can cause marked calcium oxalate irritation. Keep it out of reach and contact a vet if chewing is followed by symptoms.
