Buy Artemisia 'Powis Castle' wormwood: Silvery, aromatic foliage

This perennial is semi-evergreen so it can lose some of its leaves in winter. In colder regions or more exposed gardens, it may lose them all, but then fresh new growth appears again in spring.

  • Position: full sun
  • Soil: well-drained, fertile soil
  • Rate of growth: fast-growing
  • Flowering period: August
  • Hardiness: fully hardy

    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.

Good plant


Good plant to add interest to a boarder,

Karen g



Brilliant for drought and sun.


Foliage is very fragrant when touched and beautiful silver colour. Will withstand drought and hot sun and still look good. If cut back quite hard in Autumn, will stay in shape and produce new foliage quite quickly for the next year. Indispensable in my chalk garden!




Best near the edge of a border


I've grown many of these plants and usually take cuttings each year to produce new plants as they do tend to become leggy with bare woody stems, especially is placed deep in a border. I've take to planting them near the edge where i can easy get to them to cut back so encourage bushier growth. I like the aromatic smell when the foliage is touched. They look good next to Salvia Victor Klose






Very attractive, adding soft silver colouring to border. Grows rapidly.




So lovely I bought a second!


Really lovely foliage plant, with silver-grey tones that are a great contrast to other colours. The feathery silver looks looks stunning in front of an established purple Cotinus.




Love this silvery thing!


A lovely plant. I have a thing about silver foliage so I am building a collection in my garden.....these plants light up the borders, The leaves have a special feel, very soft, beautiful and feathery. Who needs showy flowers that fade when you can have long lasting silver leaves. I have planted mine in a sheltered sunny border with a trio of lavender plants and also a curry plant which is silver too...




Very pleased with this plant.


Did well in it's first year, has been pruned and is growing well again, I have managed to take cuttings. This is is lovely plant with attractive silvery grey aromatic foliage and is a must for any border.




fantastic quality plant


such a beautiful plant - much bigger than I thought it would be and very very healthy - I love it!!




Great foliage


Lovely evergreen blue grey foliage




Would recommend, healthy and securely packed for delivery!


Good contrast plant especially for pink/purple. Has pleasant scent and good in flower arrangements.

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

Anne Grimshaw

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

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

Christopher Robinson

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

Ruth Hamilton

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.
