Monstera

Under good conditions, Monstera deliciosa is a moderately fast grower, producing one to two new leaves per month during summer. Growth slows significantly in winter when light levels drop. A climbing support, such as a moss pole, encourages the plant to produce progressively larger and more fenestrated leaves as it gains height.

Monstera adansonii tends to grow faster than deliciosa in comparable conditions, making it a rewarding choice if you want to fill a space quickly. Variegated cultivars such as Thai Constellation grow more slowly, as the variegated areas contain less chlorophyll and produce energy less efficiently than all-green leaves.

Young Monstera plants produce entire leaves without fenestration. Holes and slits develop as the plant matures, typically from the fifth to seventh leaf onwards in good conditions. This is normal. Monstera deliciosa produces its most dramatic fenestration on mature leaves in bright indirect light; insufficient light is the most common reason for poor or absent splitting.

Providing a moss pole or climbing support also encourages larger, more fenestrated leaves, as the plant registers height as a signal to mature. If your Monstera is producing small, un-split leaves after several years, check the light levels and consider whether it has adequate support to climb. M. adansonii develops its characteristic perforations earlier than deliciosa and is a quicker route to dramatic-looking foliage.

Monstera deliciosa can reach 2 to 3 metres or more indoors when given a climbing support and adequate space. Individual leaves on mature plants can exceed 60 cm across. Growth can be managed by pruning; cuttings root readily and make excellent gifts or replacements.

For smaller spaces, M. adansonii stays more compact and trails attractively from a shelf or hanging pot. Slower-growing collector species such as M. dubia and M. siltepecana also remain more manageable in size and suit a smaller room or shelf display.

Yes. Monstera deliciosa contains insoluble calcium oxalate crystals and is toxic to cats and dogs if ingested. Symptoms include oral irritation, drooling, vomiting and difficulty swallowing. It is not typically life-threatening but should be kept out of reach of pets.

All Monstera species should be treated with caution in a pet household. If you need a dramatic foliage plant in a pet-safe space, our easy care houseplants collection includes alternatives with lower toxicity risk. Always consult your vet if you suspect your pet has chewed any plant material.

Monstera deliciosa produces large, paddle-shaped leaves with slits extending from the midrib to the outer edge. It is a robust climber that eventually needs significant height and support. Mature plants are impressive statement pieces and among the most rewarding houseplants to grow long-term.

Monstera adansonii (the Swiss cheese vine) produces smaller, more oval leaves with rounded holes punched through the centre of the leaf rather than slits to the edge. It trails and climbs readily, grows faster than deliciosa, and suits smaller spaces well. Both are excellent plants; the right choice depends on the space you have and the look you want to achieve.

Thai Constellation care is similar to standard Monstera deliciosa, with one important difference: the cream variegated areas contain less chlorophyll and generate less energy. This means the plant needs brighter indirect light than an all-green Monstera to maintain growth and produce good patterning. Avoid direct sun, which will scorch both the green and variegated portions of the leaf.

Water, feed and repot as you would any Monstera: allow the top few centimetres of substrate to dry between waterings, feed every two to four weeks in the growing season, and use a free-draining aroid substrate. Thai Constellation is tissue-cultured and produces stable, consistent variegation. Growth is slower than an all-green plant but more predictable than Albo Variegata, which can revert or produce all-white, non-viable leaves.
