    Artemisias are prized for their light, almost silver, aromatic foliage rather than for their flowers, which are dull and insignificant. This cultivar has fine, fern-like, aromatic leaves and tiny, yellow-tinged silver flowers in August. The billowing foliage of this woody stemmed perennial is ideal for a sunny rock garden or border. Although it's one of the hardiest varieties of wormwood, do plant it in a well-drained site, as the plant is likely to be short-lived in poorly drained soil.

  • Garden care: Cut back in early spring, but be careful not to cut into the old, woody stems that do not have buds unless it needs complete regeneration, as this may kill the plant. It helps if you can wait until the new buds are breaking before tackling it, as this will give you an indication as to where to make the cut. They fill out really quickly after pruning, but the tips may need pinching out to prevent them getting leggy.

  • Q:

    Why has my Artemisia turned green?

    I have had an Artemisia 'Powis Castle' for several years, most of these were spent in a container. When I moved and had a garden I planted it in the soil (clay-ish, neutral, I think). It has grown quite well but it is no longer as silvery. Why did that happen? Best wishes Anne

      Hello Anne, Silver-leaved plants are real sun-lovers, and their foliage may lose some of its shine if they don't get enough.

  • Q:

    How do I get rid of gnats?

    We are having a wedding in our garden and need to eliminate gnats. We have a small pond, which doesn't help but we really don't want to get rid of it. There will not be room to have citronella flares. Is there anything we can plant? Thank you

      Hello there, One of the nicest things to plant that will help to discourage gnats and flying menaces is lemon verbena or Lippia Citriodora. This is a wonderful plant with pretty white flowers in summer but the real attraction is its lemon scented leaves which discourage flies. It is a slightly tender plant though that needs some shelter over winter. Other plants include garlic or garlic chives, Chamomile, Artemesia, Pyrethrum and Feverfew. I hope this gives you a few ideas. Helen Plant Doctor

    Advice on planting your pre-designed Red Summer border

    Dear sir/madam I am particularly interested in buying the Red Summer Pre Designed Border. Please can you tell me whether these plants are suitable for planting in conjunction with weed inhibiting fabric. I want to minimise the amount of weeding required. Many thanks for your help Ruth

      Hello Ruth, You can plant these into the weed supressing fabric without any trouble at all, provided you make sure the fabric allows the water to drain through. All you need to do is cut big crosses into the fabric and peel back the edges to plant and then fold back the edges again. I hope this helps.
