I got this crazy idea to redo my garden and to plant only flowers that start with H. Why not? Last time I decided to redo my garden I planted only succulents. And the time before only plants with white flowers.
There are trends in the gardening world just like in any other field, and there are also gardeners’ whimsies. Planting only flowers that start with H comes under both of these categories.
As you will see, there are plenty of plants with flowers that start with H, but it does not mean you have to have only them in your garden. You can nicely mix them with what is already growing in your garden as long as they play nice together.
