The plant of the moment in serious gardens — and once you've seen one, you understand why. Yucca rostrata carries a perfect silver-blue sphere of fine leaves on a sculptural trunk, like something drawn rather than grown. It reads as modern architecture in a border, a courtyard, or flanking an entrance — and it's far tougher than it looks.These are slow-grown specimens with real trunk on them — the trunk is decades of growth, which is why a good rostrata is bought, not waited for. There's one standing outside our Chelsea showroom if you'd like to meet it first.Best space & placeFull sun, outdoors, and the freest-draining spot you have — a raised bed, gravel garden, or generous pot suits it perfectly. Hardy to around −12°C once established, provided its roots never sit in winter wet. Takes coastal wind and exposure in its stride.When to water & feedWater to establish in the first season, then largely leave it alone — this is a desert plant that finds British rainfall generous. A light feed in spring is plenty. In pots, ease right off in winter.Need to knowWinter wet, not winter cold, is the only thing that troubles it: free-draining soil or a pot raised on feet solves both. Lower leaves fade into a dry skirt as the trunk extends — leave it for the classic silhouette, or trim it for a cleaner stem.Decorative pots not included. The plant will be delivered in a plastic nursery pot.
