Worry less knowing this plant has more than just good looks. It's drought-resistant and right at home in a dry garden. It can handle almost anything, including heat, poor soil fertility, deer, and rabbits. Plant this in your garden, and it won't disappoint!

Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:

bush distance

Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

Not sure just how many plants will fit in your garden? Our calculator gives you the exact amount of plants required for your space. Simply update the values and the calculator will re-calculate accordingly. Spacing information can be found in the 'How to Grow' tab on each plant's page.

The four ordered arrived wilted and never recuperated. So sad....

The four ordered arrived wilted and never recovered. A big sad disappointment. I have grown this Artemisia in the past with success and was looking forward to another flourishing planting. It has such lovely texture, and offers a striking pale mass to the garden, and other plants seem to thrive in its vicinity. But those four plants ordered did not survive the trip to my garden.

Our friendly customer service team is here to help! Just contact us at [email protected] with your order number and photos of the plants. After further investigation, we will be able to better assist you. All orders are covered by our 60-day guarantee. We appreciate your feedback and look forward to helping! https://bit.ly/ggp-guarantee

strong, healthy plants

The weather did not cooperate with my planting plans. These plants waited a week before I could plant them, and I didn't plant them as well as I would have liked. Despite the problems, they have thrived.

Artemesia powis castle

I ordered 4 polish castles several weeks ago. They arrived in good shape and are doing great. Since they don't overwinter in Iowa, I will be placing an order for more from Great Gardens every spring.

Great Healthy Plants

Never ordered from this company so first timer. The plants were a decent size, healthy and packaged to prevent any damage during shipping. Quality product with clear instructions - what to do when unpacked and when to plant. No guesswork on your part. Definitely recommend - plan to order more plants from Great Garden Plants in the future.

Drought tolerant plant

This plant, along with other drought tolerant plants I ordered, arrived quickly, well packaged and in excellent shape -- as usual for all my previous orders from Great Garden Plants. In my previous garden (in NM), Powis Castle was my favorite plant and handled drought, heat, and neglect, adding great character as its branches thickened/twisted and aged and the beautiful soft waves of silvery fans spread out to add texture to the flower beds. In PA, we have much more rain and cold, wet winters (but are now experiencing periodic short-term droughts that even affect native vegetation), so I'm hoping my experimental raised bed with LOTS of gravel mixed with the native clay will allow it to flourish without any supplemental watering. All my plants previously ordered from Great Garden Plants are growing well, so I have high hopes this will work out well too.

Nice little plants

I'm keeping them in their nursery pots until the 104 heat wave passes. I've had the wormwood a few weeks now and they're slowly acclimating to my environment. The leaved are beautiful and will look nice next to my vegetables.

Wormwood was new to me.

I like the looks of this plant. The pale blue-green looks very cool in this very hot dry drought. So far it still looks good and is weathering the 100+° days very well.

Is it a heirloom (no GMO) plant? I will be using it as an herbal tea!

Great Garden Plants

'Powis Castle' Wormwood is a hybrid of two other varieties of artemisia and is grown for its aromatic, silvery foliage which makes it a wonderful contrast to other perennials and shrubs in the landscape. It is grown for ornamental purposes and we do not recommend ingesting it in any form.

Does Powis Castle Wormwood repel warps and yellow jackets?

Great Garden Plants

Hello! 'Powis Castle' Wormwood, with its lovely silver-gray foliage, is often appreciated for its aromatic qualities, which can deter some pests. However, there isn't strong scientific evidence to suggest that it specifically repels wasps and yellowjackets. While some gardeners believe that the strong scent of wormwood and other aromatic plants may help to keep various insects at bay, it's not a guaranteed method for controlling wasps and yellowjackets.

E

I see you have this plant zoned for Zone 6. I grew this artemisia successfully in my old garden (zone 4 in New Hampshire) but I’m hesitant to purchase for my new garden in VT (zone 4b), if you don’t guarantee plants beyond their listed hardiness zone.

Great Garden Plants

The Powis Castle Wormwood is rated for zones 6-9. The Silver mound Wormwood is rated for zones 3 - 7 if you are looking for a wormwood that is rated for zones 4. We do not stop customers from purchasing out of zones plants. Our guarantee does not cover plants grown outside of their recommended growing zones.

How big are they when they are shipped?

Great Garden Plants

Thank you for contacting us! We carry a variety of sizes. Most of our perennials are grown in a 1 quart container, which is a 4" x 4" pot. Some of our evergreen trees and shrubs are grown in a one gallon container, which is 6" round pot. The sizes are listed on the individual plant pages. As we are strictly an online nursery and ship the plants to all the lower 48 states, we have found that the gallon size is the largest to ship.

The size of the plant itself varies, depending on the variety and the time of year.
