Hi, My husband and I have two large flower beds that have relatively sandy soil. We have not had much luck planting pretty flowers that last, except Lantanna. We would like some low maintenence, higy yield and hardy flowers to make our beds look nice. Can you make any suggestions? We are more than happy to get out there and work, and to keep up with it, but we are new to gardening (obviously)and need some 'easy' ones to start with |
