Here are some other ideas to turn your garden blue. I’ve included some of those that are mauve and purple as well, as they just look so great in a blue garden.
One of my absolute favorites when it comes to trees is the jacaranda. They are a picture when they are in flower. The jacaranda is a deciduous tree and so it ends up looking like a dead stick in winter before it regains its leaves and then flowers. But there is nothing prettier than that jacaranda blue. I once wrote a poem called exactly that, about the small jacaranda I had to leave behind when we moved to Orange, as they won’t grow in the cold there.
As soon as we moved here to the coast I went out and bought one. At the moment it is in a pot. Mick does plan to make a smaller garden area for it in the front lawn. It has tripled in size since being moved, so it obviously didn’t like the first position. Sometimes gardening is about finding exactly the right spot for a plant. On that note, be aware jacarandas have invasive roots so do not plant them near sewer pipes or too close to the house.
When it comes to flowers those in the blue shades include sweet peas, plus you get such a heavenly perfume with them as well and they make great cut flowers. In fact, the more you pick them, t he better they will flower. Other blue flowers are Dutch irises, grape hyacinths and blue salvia and don’t forget agapanthus. They come in a heavenly blue.
Hydrangeas are another shrub that gets masses of flowers. We have a blue one in our garden. If you want to make the color strong add aluminum sulfate. They are very hardy. Mick once took a mattock to one which had been grown in the wrong place by previous owners of the house and kept intruding on the driveway. It still came back and flowered amazingly. At which point he decided they were pretty well indestructible.
