We have a 2 acre south facing site in W. Mayo, very windy, 1/2 mile from the sea. Most of the site is peaty loam, very fertile although somewhat acid & wet in the lower part; also sandy soil on the hill (poor fertility, very stony). Up to now, we have focused on veg & fruit. We would like to add all-year round colour, esp. perennial shrubs & trees, yellow, blue, red/pink, etc. Maybe too windy for camelias. Any suggestions (top 10, say) ?
