This is an all-round design inspired by the lovely Iris Pallida leaves and the Aquilegia that seed themselves around the garden.
Iris Pallida, Aquilegia, Roses Alstromeria Euphorbia Robbiae Astrantia “Shaggy” Bergenia “Tubby Andrews” Ivy, Juniper
Use a large shallow dish and impale some oasis foam on a frog stuck to the bottom with oasis fix or similar. Place the upright leaves in the centre. Roughly 1 ½ times the width of the dish used. Add the Aquilegia at a slightly shorter height. Cover the sides of the dish with overlapping green foliage (Bergenia, ivy and juniper. Group the Roses into two groups either side of the Iris and then cut the Alstromeria flowers and place them into groups lower down. Use the Euphorbia to cover the spaces where oasis is showing and finally add the Astrantia to lighten up the colour scheme.
If you are using materials from your garden and do not have the same as me, try to choose contrasting textures and forms of whatever you can find.
