Eucomis comosa Johannesburg - Pineapple lily

Eucomis comosa 'Johannesburg', also known as the Pineapple Lily, is a bulbous perennial with tropical charm native to Southern Africa. It forms a rosette of wavy, light green foliage, often tinted purple, topped in summer with an erect flower spike reminiscent of a pineapple. In borders, edging or pots, it structures summer displays with elegance and originality, provided its bulb is protected in severe frost. This cultivar is distinguished by a denser, more compact flowering than the type, with cream-white flowers with a pink heart, ideal for contemporary gardens or exotic settings.

Eucomis comosa 'Johannesburg' belongs to the botanical family Asparagaceae. The type species Eucomis comosa (syn. Asphodelus comosus or Eucomis punctata) originates from Southern Africa, where it grows on damp grassy hills, banks or rocky terrain in climates with summer rainfall. It is also known by the common names Pineapple Plant or Pineapple Lily. This cultivar is a robust horticultural selection, distinguished by a dense flower spike more compact than that of the type species. The plant adopts a rosette habit, with a moderate to fast growth rate depending on conditions. In the ground, it typically reaches 60–75cm in height and a width of 50cm. Propagation occurs naturally by offshoots appearing around the main bulb after a few years. The flowers form an erect, dense raceme, covered with about a hundred small cream to white stars dotted with a pink-green eye, topped with a tuft of bracts similar to a pineapple. Each flower measures a few millimetres. Flowering occurs in summer, from July to September, with a sweet fragrance, sometimes suggestive of coconut, attracting bees and hunting wasps. The deciduous foliage forms a rosette of light green, lanceolate leaves with wavy margins, sometimes spotted or tinged purple depending on exposure, measuring 20 to 70cm long by 3 to 15cm wide. The root system consists of a large, flattened, 10–15cm diameter bulb with roots arranged around its rim, producing numerous offshoots.

In the splendour of summer, Eucomis ‘Johannesburg’ emerges from the ground like a botanical sculpture, geometric and exotic. Hardy to -10°C, this plant thrives equally in sun or partial shade, in rich, moist and very well-drained soil. Placed at the edge of a border or in a pot on a sunny terrace, it has a calm but unusual presence, pairing well with large foliage such as that of Melianthus major. To intensify this play of textures and volumes, choose the vertical flowering of Kniphofia ‘Tawny King’ or the dark of Dahlia ‘Chat Noir’. Its long-lasting and decorative flowers are also perfect for creating superb exotic cut flower arrangements. It is easy to grow in pots, allowing it to be protected over winter in colder climates.
