i've made mine high rise from 6 pallets. The middle is stuffed with straw and then the fronts have hollow stems, bricks with holes or pine cones. I used strips of wood t make a shallow bed on the top layer, lined it with weed fabric and filled with compost then planted with assorted sedums and mulched with a mix of gravel and shells. The shells hold rain water so are good for insects to drink from.
The picture shows it when first made 2 years ago. Since then the sedums have spread. I've had to replace the chipped bark and pine cone layers because visitors and birds have strewn them about but it's become a haven for hedgehogs, amphibians from the pond just below it and insects.
The frames on the side are from a dismantled wooden obelisk and will support the campsis if it ever gets big enough. Keeps being knocked back by hard winters.
