Agave geminiflora, the twin flower agave, is a fine leaved succulent forming a dense sphere of narrow dark green leaves, each edged with fine white filaments. Older plants can carry two hundred leaves or more, giving the rosette an unusually soft, almost grassy texture for an agave.
It grows in full sun to part shade in free-draining soil, and it keeps the best colour in an open position. Warm temperate, coastal and drier inland gardens suit it, and established plants take light frost. Growth is slow at about 15 to 30 centimetres a year, with very high drought tolerance.
The rounded, fine textured outline softens hard landscapes without giving up structure. Use it in rockeries, gravel beds, courtyards and low water schemes, or in pots where the shape can be viewed in the round. It sits comfortably beside grasses and soft planting where a rigid agave would jar.
Frequently Asked Questions
About Twin Flower Agave
What is Agave geminiflora?
It is a Mexican succulent grown for its dense, spherical rosette of very narrow dark green leaves, each fringed with fine white threads. It carries far more leaves than most agaves, which is why the plant reads as soft and textured rather than sharp. The common name is twin flower agave.
How big does Twin Flower Agave get?
It reaches roughly 0.6 to 0.9 metres in height and up to about a metre across, forming a neat dome. Unlike many agaves it rarely produces offsets, so it stays as a single, well defined rosette instead of spreading into a clump. Plan your spacing around that fixed final size.
Does it have sharp leaves?
The leaves are narrow and flexible with fine white threads along the edges, and there are no marginal teeth at all. There is a slender spine at each leaf tip, but the leaf itself bends rather than stabs. It is one of the friendlier agaves for gardens where people pass close by.
Is it drought tolerant?
Highly. Once established it lives on rainfall through most of southern and coastal Australia and only wants water during prolonged heat. It is a standard choice for waterwise and unirrigated planting schemes. The greater risk is too much water, particularly in heavy soil, where the crown will rot.
Can it grow in pots?
Yes, it is one of the best agaves for container growing because it stays a single rosette and keeps a clean rounded shape. Use a free-draining succulent mix in a pot roughly the width of the rosette. Water when the mix dries out, and hold off almost entirely through the winter.
Where is it best planted in Australia?
It suits Perth, Adelaide, Melbourne, Sydney and the drier inland, wherever drainage is good and summers are warm. It also grows in south east Queensland, though wet summers there mean it should sit on a mound or in a raised bed. Avoid cold, wet tableland sites in open ground.
How do I care for Twin Flower Agave?
Very little is needed. Water it in for the first summer, then only during long dry spells. Trim away dried lower leaves at the base to keep the dome clean. Do not cut the white filaments from the leaf edges. A light spring feed is optional and pruning is never required.
