Elaine, narrow to say the least.
plants like osteospermum....the hardier Tresco Purple and Cannimgton Roy will cascade and flower all summer. Take cuttings to ensure you have replacement plants should a hard winter hit them.
nepeta? It will form a mound of semi evergreen foliage that will also cascade. Blue flowers all summer, easy, tough and attractive. A good alternative to lavendar. Lavendad would grow there but not cascade.
helianthemums...sun roses? Evergreen with flowers of white,,pink, yellow, orange and red with allshades in between.
Aubretias, perennial alyssum, arabis, erigeron would all grow there.
Check out comvolvulous cneorum too.....beautiful velvety silver foliage all year round with pure white summer flowers.
Grasses too......carex buchanii is an evergreen upright neat foxy red grass; carex Bronze Form is similar but has a delightful mounded habit. Stipa tennuissima is a small evergreen grass with billowing beige white flowers in summer. Not a grass but looks like one is Libertia Taupa.....a small evergreen olive coloured plant with shades of red and orange and small white flowers
A taller growing thyme..Silver Posie, is a silvery grey evergreen with pink flowers in spring and summer.
a combination of the above will give interest all year round, a variety of shapes and forms and masses of colour
