Ask Marie: Can you recommend some herbaceous plants to give me some height in my flower borders?
Tall, slim and elegant, Verbena bonariensis gives both height and airiness to any border. It has tiny, clustered purple flowers, held aloft on slim stems to a height of around 1.5m. Best of all, it will seed itself.
Achillea Cloth of Gold and Veronicastrum virginicum Fascination will both give the height you need and will also give coverage, filling out nicely over time.
Phlox is a good solid choice, as are the taller varieties of helenium. Climbing roses work really well, too.
Myself and my granddaughter want to attract more wildlife into the garden, especially bees. Which flowers would be good to plant?
In order to attract wildlife into your garden, you need to know what they like. Bees are after nectar, so foxgloves are ideal because of their long flowering season. Eryngium, or sea holly, is a great source of food for bees. Marigolds are also a good choice, and lavender and chives will keep pollinators coming for most of the summer.
