Koko Flanel (June) Koko Flanel (April) Koko Flanel Very silver, heavily cobwebbed. £2.60 Out of stock. I love everything about this plant - the fuzzy, cob-webbed, silvery leaves, the shape and the way it forms perfect clumps. Even the name intrigued me - 'Koko Flanel' was a popular Belgian comedy film released in 1990. Bred by André Smits (B) 2003 Well-rooted, established plants, sent in their pots.
