Colocasia esculenta ‘Mojito’

Origin and botanical background of Colocasia esculenta ‘Mojito’

The species has been grown and moved by people since prehistory, linking its origins broadly to tropical Asia and its early cultivation to New Guinea and the Pacific. Its natural background is wet lowland vegetation: marshes, river margins and rain-fed hollows where warm air and persistently moist ground support rapid, expansive leaves.

Care through leafy growth and seasonal change

Repotting

Colocasia esculenta ‘Mojito’ needs repotting when roots distort the pot, offsets crowd the rim, water no longer spreads evenly or old mix becomes muddy. Work during warm active growth, preserve the central corm-like base and remove only dead roots.

Light

Place Colocasia esculenta ‘Mojito’ immediately at a bright south-, west- or east-facing window and acclimate it to several hours of sun. Strong light keeps the large mottled leaves upright and supports rapid replacement growth.

Watering

Water Colocasia esculenta ‘Mojito’ before the root ball dries through. Active Colocasia roots tolerate consistently moist mix and can use a shallow fresh-water reservoir in very warm bright conditions, but muddy stale water still removes oxygen.

Humidity and airflow

Colocasia esculenta ‘Mojito’ benefits from moderate to high humidity, particularly as a large mottled leaf unfolds. Average room air may cause dry margins even when the root ball is moist.

Fertilising

Apply a balanced complete fertiliser to moist mix at a low dose while Colocasia esculenta ‘Mojito’ is actively replacing leaves. Continue lightly through winter if the plant remains active; stop when it becomes cool or leafless.

Light and leaf care

Allow the mottled leaves to face the window naturally rather than repeatedly turning an opening leaf towards a new direction. Wait until an opening leaf has firmed before turning the container, and remove a collapsed or fully yellow stalk with a clean cut at its base.

Diagnosing Colocasia ‘Mojito’ problems

Black and dark-purple flecks spread across green leaves

Irregular dark marbling is the defining ‘Mojito’ pattern and differs naturally between leaves. It should remain flat and firm. Soft halos, expanding dead centres or marks accompanied by pest residue are damage and should be isolated from the normal pattern before action is taken.

Striped petioles bend sharply

Patterned stalks are normal, but a crease can follow handling, a top-heavy leaf or uneven water supply. Support a firm bent petiole and stabilise conditions; it will not straighten fully. Cut it away if the bend becomes wet, soft or begins to decay toward the crown.

Leaf edges curl and crisp

A dry root ball or hot direct exposure can crisp the thin margin, while cold roots may cause a whole leaf to hang. Check moisture and temperature before watering. Restore even moisture during active growth and protect newly acclimating leaves from intense afternoon sun.

Fine pale stippling crosses both green and dark areas

Spider mites create tiny feeding points independent of the normal black flecks and may add webbing beneath the blade. Isolate ‘Mojito’, confirm moving specks with a lens and repeat a labelled mite treatment over both leaf surfaces and petiole bases.

The newest rolled leaf and crown turn soft

This is an urgent growing-point and corm-rot warning. Remove wet substrate and cut away decay until only firm, clean corm remains. If softness has passed through the central bud, save any separate firm offset rather than retaining the collapsing crown.

Colocasia esculenta ‘Mojito’ is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

Where does the name Colocasia esculenta come from?

Colocasia comes from ancient Greek kolokasion, a name for an edible, corm-bearing plant. Esculenta means edible, reflecting taro’s long history as a food plant.

Heinrich Wilhelm Schott established the genus Colocasia in 1832 in Meletemata Botanica, page 18.

Carl Linnaeus first described it as Arum esculentum in 1753 in Species Plantarum, page 965. Heinrich Wilhelm Schott later placed it in Colocasia as Colocasia esculenta in 1832 in Meletemata Botanica, page 18.
