Begonia escargot / From Annie's Annuals: Looks snail-like with hand-sized, high-contrast, silver and deep green variegation. 'Escargot' is a tender but strong-growing rhizomatic rex hybrid Begonia. Forms a dense clump, 12"x12". Warmth and humidity-loving, you can grow it outdoors best in a container. Otherwise, grow it as a wondrous houseplant, happily resting on a pebble/humidity tray with a twice-a-week watering and regular fertilizing. Cut back to soil level to rejuvenate.
