Melon spurge
BeginnerEuphorbia meloformis
A melon-shaped Euphorbia with eight ribs striped light green and purplish-brown. Old flower stalks persist on the plant, a key difference from the similar E. obesa.
About
Euphorbia meloformis is endemic to the Eastern Cape of South Africa, around Kariega (Uitenhage), Gqeberha (Port Elizabeth), Makhanda (Grahamstown) and Peddie, where it grows in short grassland and gaps in succulent thicket on flats of limestone or calcrete. It is a small, spineless succulent rarely over 10 cm tall, forming a dome with a flattened top above a long taproot. The body is 5–10 cm across, with eight ribs striped light green to purplish-brown and reddish cross-bands. It is usually solitary but may clump with age. Plants are male or female; small yellow-green flowers appear at the top from early summer to autumn (November–March in habitat), and the flower stalks persist long afterwards. It differs from the similar E. obesa in its long-lasting stalks, finely hairy ovaries and wider spacing between tubercles and flowering points. The South African Red List rates it Near Threatened because of its small range and illegal collecting. The related subspecies valida is larger and prized when thick, hardened stalks persist. In Japan it is a standard item at specialist nurseries and is also seen in home centres. The white latex from wounds irritates skin and eyes, so take care.

Growing Tips
Light & Placement
From spring to autumn keep it in sun and good air, out of the rain, with about 20–30% shade to prevent sunburn when conditions change.
Watering
Japanese sources class it as a summer or spring–autumn grower; either way it grows from spring to autumn. Water thoroughly when the mix is dry, less often on hot nights in midsummer, and keep it dry through winter dormancy.
Temperature & Overwintering
It has some cold tolerance but must be protected from frost and freezing; overwinter it in a sunny room or cold frame. Japanese references give 3–5°C as its limit.
Soil & Repotting
Use a free-draining mix with slow-release organic fertiliser mixed in. It has a long taproot, so a deeper pot suits it.
Propagation
Plants are male or female, so both are needed for seed. Offsets, when produced, can be removed and rooted.
Pests & Cautions
The white latex from wounds strongly irritates skin and eyes; wear gloves when repotting and do not rub your eyes.
