We have three acers thriving in large tubs, all moved here with us. Most aren’t too happy in very windy positions so something to bear in mind. We also have a camellia and two rhododendron loving being in containers, remember they can and do grow fairly big, Spring flowers from those. Lavender is good for the summer, smells nice and the bees love it. Patio roses are happy in containers, shrub roses if the container is large. Bamboo seems to be happy enough in a container too. This year instead of bedding plants in our large planters outside the conservatory we have dahlias, first time we’ve put them in containers and they look stunning. Watering can be tiresome, the bigger the container the better it holds moisture. We put gravel or decorative stones on many of our containers, helps keep the moisture in. Most of our planting is now in containers, saves bending, if I like a plant I’ll often try it, usually they survive in spite of me . Enjoy choosing luckygirl, a wander around a local nursery will give you many more ideas I’m sure.
