The supercharged succulent has gone into overdrive, bearing an enormous inflorescence that’s dwarfing all but the tallest green-fingered customers. Mangave ‘Moonglow’ is a relatively new plant introduction that’s rising in popularity as UK gardeners seek drought-tolerant plants that will flourish in a warming world. Nursery Supervisor at Chestnut, Richard Holman, said: “The Mangave is a cross between an agave and manfreda – a striking introduction with rosettes of sword-shaped, blue-green leaves that are mottled with contrasting deep-purple spots. “While mangave takes less time to burst into flower than its agave parent, it’s unusual to see several of our collection putting on a spectacular show in late winter. They must love basking in the sunny, warm atmosphere of Chestnut’s shop and glasshouses!”When fully open, the towering flower spike is expected to erupt into an exotic display of yellowy green flowers.
