Alocasia macrorrhizos Violacea - Elephant's ears plant

Alocasia macrorrhizos Violacea or ‘Black Stem’, also known as Elephant’s Ear, is a must-have houseplant for lovers of exotic botanical decor. With its strikingly elegant black stems and large, glossy, veined leaves, it transforms any room into a miniature urban jungle. Perfect for modern, bohemian, or minimalist interiors, it thrives in bright spaces. Avoid drafts and maintain high humidity to protect its spectacular foliage.

Alocasia ‘Black Stem’ is an upright perennial with rapid growth, reaching 1.50 to 1.80 metres in height with a spread of 90 to 120 cm. These dimensions depend on pot size and growing conditions. It is a rhizomatous plant from the aroid family, related to Arums. This cultivar is prized for its black stems, which contrast beautifully with its deep green, heart- or arrow-shaped leaves, growing up to 60 cm long. The thick, glossy leaves have an almost artificial-looking texture. As it grows, the plant branches from the base, maintaining its elegant form. When an old leaf is removed, two new ones take its place. This Alocasia rarely flowers indoors. Its inflorescences are subtle, spathe-type, and appear as cream-coloured bracts. Note that it is toxic if ingested.

Native to Southeast Asia, Alocasias are tropical plants that thrive in warm, humid climates with partial shade. Though stunning, they can be challenging to accommodate in indoor environments where the air is too dry. Their roots are also sensitive to both overwatering and underwatering. The ideal temperature for cultivation is around 20°C.

Indoors, Alocasia ‘Black Stem’ quickly becomes a focal point due to its imposing presence and sophisticated appearance. Place it in a large white or black ceramic pot to accentuate the contrast of its stems and make it stand out in a minimalist or contemporary setting. It also shines in tropical or bohemian spaces, surrounded by rattan, raw wood, or natural fibre elements. To enhance your decor, pair it with plants like Monstera or Calathea sanguinea, which share its need for indirect light and high humidity. Position it near a sheer-curtained window or in a temperate conservatory to encourage full growth. On light stone flooring or in a high-ceilinged room, it becomes a striking feature, elevating a decor that’s both natural and chic.
