The ultimate midsummer bee plant with soft, stubby blue bottle brushes tinged with black- purple -the antidote to sunny orange calendulas

Val Bourne - Garden Writer

  • Position: full sun
  • Soil: well-drained, fertile soil
  • Rate of growth: average
  • Flowering period: July to October
  • Hardiness: hardy (borderline)

    Hyssops are great for adding height to a border, with whirls of long-lasting, tiny flowers arranged like a bottlebrush and pointed, aromatic fresh green leaves that are attractive to butterflies. They are short-lived though, and may need replacing every few years, especially after a cold or wet winter. 'Black Adder' has smoky, violet flowers on long spires from July to October. Try it as part of a Mediterranean scheme or in a sunny, well-drained border among ornamental grasses.

  • Garden care: Don't cut back the faded flower-stems until early spring, as they provide interest in the winter months. Lift and divide congested colonies in spring.

    Use in mixed borders. Tall and stately, mixes well with many colours. Needs little attention. Loved by bees and butterflies. Fully hardy on my well draining chalk soil in the South.

      Comments about Agastache 'Blackadder':

      As I have very dry soil in my garden I use this plant in containers. It provides a striking foil when planted with Heleniums -a real zing of a combination. I have also planted it with a variegated Euphorbia 'Glacier Blue' and Echinacea 'White Swan' in a container providing an attractive colour combination. It is easy to place the containers within a border to provide added interest.

          Best used as a summer long flowering plant as a vertical feature. Attracts bees and butterflies, superb colour and aromatic foliage. What more could you ask for in a summer perennial?

              Have several of this plant around the garden, they flower continuously and are beloved by bees. Need minimal care. Recommend them highly.

              Tender perennials, such as pelargoniums, fuchsias, osteospermums and marguerites look great all summer, but unless they are given protection from the harsh winter weather, they will need to be replaced each spring. If you can do this, they will last for y
