I've had an unkempt hilly back garden terraced - it's now lawn with two beds for veg/flower. Since the garden still slopes upwards I don't want anything too tall in there, say 18inches max - I was told about an evergreen plant, blue-purple flowers for ground cover called something like see-osaurus? I should have written it down because I've obviosly got the name wrong, can't find it anywhere. Any suggestions? I'm looking for texture, green and white, bit of purple, easy maintenance foliage and maybe some herbs and veg in there too. And if anyone could suggest a tall shrub in a pot I can use to fill a gap to screen next door garden, you'll have made my day!
