Ensete glaucum - Snow Banana

Ensete glaucum, also known as the Snow Banana, is a large herbaceous plant that can reach several metres high. It is extremely decorative with its large, long leaves that have a blue-green hue and its bottle-shaped base. With rapid growth in fertile and moist soil, its tropical silhouette will be a strong visual focal point in an exotic-inspired flower bed. This banana tree can be planted in the ground only in regions with particularly mild winters.

Ensete belongs to the Musaceae family, which is mainly composed of Musa (or true bananas) and the beautiful Golden Lotus, or Musella lasiocarpa. While the Musa genus has about sixty species, there are only seven species in Ensete, which closely resemble true bananas. Less common than the Abyssinian banana tree (Ensete ventricosum), some cultivars of which are used for ornamental purposes, Ensete glaucum is native to East Asia (Nepal, Vietnam, China, Thailand, Myanmar). It grows in the mid-mountain regions at altitudes ranging from 800 to 2700 metres, which explains its relative hardiness (to approximately -4°C).

This is a plant with tuberous rhizomes, mainly propagated by sowing, as the plants do not produce suckers and therefore cannot be divided. Like other Musaceae, the Ensete does not form a trunk, but what is called a pseudostem, which is a rigid structure formed by the sheaths of the leaves clustered together. This pseudostem is flared at the base, or even swollen in some specimens, similar to bottle palms, and is covered to varying degrees with a whitish bloom. The leaves are very large and elongated, reaching a length of 1.40 to 1.80 metres, with a width of 35 to 50 cm. Carried by petioles about forty centimetres long, they stand upright in the centre and gracefully arch towards the periphery, creating a spectacular volume of vegetation. This Snow Banana can reach a height of 4 to 5 metres, with a spread of 3 to 4 metres. The foliage is a beautiful bright green with blue-green highlights, and the cluster of leaves, firmly anchored on the widened base of the pseudostem, gives the plant a majestic appearance.
The flowering, rare in our climate, is equally impressive. The large green flowers, hanging downwards, consist of a central axis adorned with 10 to 20 bracts arranged in a spiral. In its native regions, the cylindrical flowering of this Ensete can exceed 2 metres long and then produce blackish-purple or grey-green fruits resembling bananas, measuring 9 cm in length and 3.5 cm in diameter. They are dry and inedible and contain large, round, black seeds, 1.2 cm in diameter. The plant is monocarpic and dies after fruiting.

Ensete glaucum is a great choice for enthusiasts of exotic plants who have a garden in a mild climate, with infrequent and mild frost. You can easily create a tropical scene by creating a flower bed and adding other plants with distinctive silhouettes. Syagrus romanzoffiana, with its coconut tree-like appearance, will fit perfectly, as this fast-growing palm tree can exceed 10 metres high and has an equally exotic silhouette as your Ensete. Place Strelitzias at their base, the famous Bird of Paradise plants with flowers recognisable for their unique design and vibrant, eye-catching colours. Hedychium is also a genus rich in species and varieties, with exuberant foliage and refined flowers in long white, yellow, or orange spikes, which fit well in a tropical scene.
