Equisetum camtschatcense - now this is a weird plant! Prehistoric in appearance, it produces hollow, thin evergreen rods that grow to 5 ft tall and are translucent when backlit by sunlight. Flower arrangers adore the foliage as the cut stems are great for bending and twisting and create dramatic interest in modern arrangements. Madly invasive, it's main aim in life is to spread everywhere so you must use all your wiles to keep it contained if you are to enjoy it safely. Plant it into a large pot with all escape holes sealed up and sink the whole caboodle into ground, it loves being in water so won't mind there being no drainage. It is also fab plunged into the margins of a pond. For best results, place in splendid isolation, as this plant is a natural born show off.
