Agave 'Shaka Zulu' is a show-stopping architectural succulent and one of the most cold-hardy large agaves you can grow outdoors in Britain. Bred from the famously tough Agave ovatifolia (the Whale's Tongue agave), it forms a beautifully symmetrical rosette of broad, cupped leaves in a soft powder-blue that holds its colour right through the year. It is a true centrepiece plant, equally at home in a contemporary gravel garden, a Mediterranean-style border or a statement pot by the door.
Why gardeners want it
Among the wave of hardy exotics now grown in the UK, this is one of the best. The leaves are wide, smoothly arching and architectural, each finished with a neat terminal spine, and the whole rosette has a sculptural, almost geometric poise that few other plants match. Compared with a typical tender agave plant, 'Shaka Zulu' shrugs off cold far more readily, making it a reliable choice for adventurous gardeners.
- Striking powder-blue, year-round evergreen foliage
- Exceptional cold tolerance for such a bold agave
- Low-maintenance and drought-tolerant once established
To get the best from it, plant in full sun in a warm, sheltered spot facing south or west. Sharp drainage is essential, so work plenty of grit into the soil or plant into a raised bed; chalk, sandy and loam soils all suit it, across the full pH range. The plant copes easily with dry summers and actively prefers it lean and gritty. Hardy to roughly -10C to -12C when dry, it is winter wet rather than frost that does the damage, so keep the crown free-draining. Expect a slow-building rosette reaching around 90cm to 1.2m across over many years. In colder or wetter gardens, grow it as a potted agave plant in the UK and shelter it over winter; like the species Agave ovatifolia, it makes a superb container specimen.
Every Agave 'Shaka Zulu' we send out is a strong, well-rooted, carefully grown plant, hand-selected and packed to arrive in top condition, ready to become the standout feature of your garden for years to come.
-
It is one of the most cold-hardy large agaves, drawing on the toughness of Agave ovatifolia, and will tolerate temperatures down to around -10C to -12C if kept dry at the roots. The real enemy is winter wet, not cold, so in most of the UK it succeeds outdoors year round in very free-draining soil or a raised, gritty bed; in colder or wetter areas grow it in a pot and move it under cover for the worst months.
-
Give it as much sun as you can. A warm, south or west-facing spot in full sun produces the tightest, most colourful powder-blue rosette and helps the plant stay dry and firm through winter. It will survive in part shade but growth is looser and it is more prone to rot.
-
Expect a bold, symmetrical rosette of roughly 90cm to 1.2m across and around 60-90cm tall once established, building slowly over many years. It is a real architectural centrepiece rather than a fast filler.
-
Yes, and for many UK gardeners a container is the easiest option. Use a deep pot with plenty of drainage holes and a gritty, free-draining compost, water sparingly in summer and keep almost dry in winter. Potted plants can be moved into a porch, greenhouse or against a sheltered wall to dodge prolonged cold and rain.
-
Treat it with respect. The leaf sap can irritate skin and is mildly harmful if chewed, and the firm spine at each leaf tip is genuinely sharp, so site it away from paths and play areas. Trimming the very tip of the terminal spine is a common, harmless way to make it more child- and pet-friendly.
