I've just had a bunch of shrubs taken out from an east-facing partly-shaded bed against a house wall -- Viburnum Tinus and Aucuba Japonica. The situation suited them perfectly, to the extent that they were difficult to manage as they grew like topsy and needed cutting 2 or 3 times a year to control the height; also the viburnum tinus and the bed underneath was infested with viburnum beetle that we'd tried for 10 years to control without success.
I'm looking for a low maintenance evergreen (or near evergreen) option to replant that bed (we're working our way around the garden to reduce the workload as neither of us are getting any younger or healthier.) Ideally, it would have some fragrance as the bed borders the path to the front door. We want to plant through weed membrane and pebbles to minimise the weeding needed (and not have to deal with leaf drop on the pebbles which always discolours them). I want low/medium height stuff to make the garden look more open than it did with the oversize shrubs). I'm not bothered about flowers, certainly don't want to dead-head regularly.
The bed is partly shaded and sheltered by a hedge 130cm (4.25ft) high and 7m (23ft) away. Soil is clay, but we've had success with plants needing better drainage by adding a lot of grit, and we're willing to do that here. Climate: Gloucestershire/Wiltshire borders in the UK, so plants need to be hardy to -5° C. (23°F). (We've had worse, but not often). The bed is 4.5 meters (15 feet) long and 1.2 meters (4 feet) deep, so I'd like some variety in the planting.
Current thoughts are a mixture of English lavender, prostrate rosemary and euonymus, but it seems uninspiring.
What options should I be considering in the mix?
