Swiss Cheese Vine

# Monstera adansonii (Swiss Cheese Vine) — Care and Problem-Solving Guide

Monstera adansonii is frequently confused with its larger relative Monstera deliciosa — both are called 'Swiss cheese plant' in popular usage. But adansonii is a genuinely different species with distinct characteristics: smaller overall size, oval rather than broad-lobed leaves, and holes (fenestrations) that appear as circular or oval perforations throughout the leaf surface rather than the split-to-edge design of M. deliciosa.

The most practically important difference: adansonii's fenestrations appear on relatively young plants in good light conditions, without requiring a moss pole or support structure. This makes it one of the most accessible 'rare-looking' plants for beginners.

Light

Monstera adansonii shares M. deliciosa's preference for bright indirect light but is somewhat more tolerant of lower light conditions in terms of fenestration development. In medium indirect light, adansonii still produces holed leaves — though fewer and smaller holes than in bright light. In genuinely low light, fenestrations reduce but the plant doesn't become the bare vine that M. deliciosa becomes in similar conditions.

Direct sun causes the same bleaching damage as on other Monstera — keep behind a sheer curtain if near a south or west window.

Watering

The watering approach is identical to M. deliciosa: allow the top two inches of soil to dry between waterings. Adansonii is somewhat less drought-tolerant than its larger cousin — its leaves are thinner and the plant shows water stress (drooping, curling) more quickly. Check soil every five to seven days during active growth.

Growth Habit

Monstera adansonii is a natural climber but adapts beautifully to trailing in hanging baskets. When allowed to trail, it produces the characteristic cascading vines with multiple holed leaves. When provided a support (moss pole, bark slab, or trellis), it grows upward and produces progressively larger, more heavily fenestrated leaves — approaching the dramatic size of mature M. deliciosa leaves in bright conditions with good support.

Common Problems

Yellow Leaves Overwatering is the primary cause. Check soil moisture — if consistently moist, allow to dry further between waterings. Single yellow older leaves are natural senescence.

Root Rot Same mechanism and treatment as M. deliciosa. Adansonii may show symptoms slightly earlier because its thinner stems don't hide rot as well as the thick stems of deliciosa.

Holes Disappearing (No Fenestration) If adansonii is producing new leaves without holes, light is almost certainly insufficient. Unlike M. deliciosa, where juvenile leaves are expected to be hole-free, adansonii should be fenestrating on any mature plant in adequate light. Move to brighter conditions.

Leggy, Sparse Growth Same light-related etiolation as other Monstera. Prune back and provide more light.

Spider Mites Most common in dry winter air. Treat with water spray and neem oil. The thinner leaves of adansonii show mite damage (stippling) more visibly than M. deliciosa.

Thrips Adansonii's smaller, more numerous leaves provide more feeding sites for thrips. Look for silver streaking and distorted new leaves. Treat with spinosad or neem oil spray.

Wide Leaf vs Narrow Leaf Forms

Monstera adansonii circulates in the plant trade in two visually distinct forms, commonly labeled 'wide form' and 'narrow form,' differing in overall leaf shape and the density and spacing of the fenestrations. The narrow form has more elongated, slender leaves with fenestrations that sometimes run closer together, while the wide form produces broader, rounder leaves with a different hole spacing pattern. Both forms share identical care requirements, and the distinction is a matter of collector preference and appearance rather than a difference in difficulty, though narrow-form plants are sometimes considered slightly more sought-after among collectors specifically for their more delicate look.

Variegated Cultivars

Beyond the standard green species, variegated Monstera adansonii cultivars circulate with white or cream patches mixed into the green leaf, sold under names like 'Aurea' or 'Variegata' depending on the source. As with most variegated aroids, these cultivars grow more slowly than the plain green form due to reduced chlorophyll-bearing tissue, and they typically want brighter light to maintain strong variegation without gradually reverting toward solid green growth. Variegated adansonii also commands a considerably higher price than the common green form given its relative scarcity and slower propagation rate in commercial production.

Why It's a Popular Beginner 'Rare Plant'

Because its distinctive fenestrated leaves and trailing or climbing versatility give it visual appeal similar to pricier, harder-to-grow aroids, while its actual care demands remain genuinely beginner-friendly, Monstera adansonii occupies a useful niche as an entry point into the more collector-oriented side of houseplant culture. Growers who successfully keep adansonii thriving often find the transition to trickier variegated cultivars or genuinely rare aroid species considerably less daunting, since the fundamental care skills involved (bright indirect light, appropriate drying between waterings, chunky well-draining mix) transfer directly across most of the wider aroid family.

Fruit and the Species Name Origin

In its native habitat, mature Monstera adansonii produces small edible fruit similar in principle to the better-known fruit of Monstera deliciosa, though considerably smaller and less commonly discussed, since indoor-grown specimens kept as houseplants essentially never flower or fruit under typical home conditions. The species is named after French naturalist Michel Adanson, who documented plant life in West Africa and other regions during the 18th century, though the plant itself is native to Central and South America rather than anywhere Adanson personally collected — the naming reflects broader botanical classification conventions of the era rather than a direct connection to its native range.
