Raspberries and cream anyone? Streptocarpus ‘Titania’ has scrumptious bicolored, ruffled blooms that are white in the upper half and deep cerise in the lower half – they look almost good enough to eat! Streptocarpus make great houseplants, with clusters of exotic-looking blooms produced from March all the way through to November in an endless array of vibrant shades and colour combinations, rising above thick, wrinkled, furry green leaves. Height: 25cm (10in). Spread: 30cm (12in).
