Artemisia ludoviciana albula (or A. albula) Silver King, often referred to as wormwood
‘Silver King’ artemisia is a foliage plant that grows easily. It’s deer resistant and needs low water. Once it gets established it produces a lot of stems. You’ll cut the stems. It spreads fairly fast by rhizomes, so give it some room. It may creep into your other flowers. But you may not mind that, it is a nice filler for fresh bouquets and it’s a great filler when it dried for wreaths.
The species is native to deserts and mountains of western US. There are two other varieties than Silver King, there’s ‘Silver Queen’ and there’s ‘Valerie Finnis’. More on those below.
These are the best Artemisias for use as cut foliage and dried foliage. Don’t confuse them with ‘Powis Castle’, or other landscape plants,
What Artemisia Flowers are Like
Flowers appear at the ends of the foliage stems. The buds appear as little silvery balls and open to small yellow, insignificant flowers. It’s best to harvest them before they open, because the flowers darken when dried. But in bud they add texture to the foliage. You may end up harvesting the foliage before the buds appear.
What the Plants are Like
Silver King grows to about 3 ft. tall. It looks like just stems growing up, the foliage is slightly divided into three to five lobes. Many artemisia foliage is fragrant, but this one is not.
Another variety is ‘Valerie Finnis’. It’s shorter than Silver King, at 1½ ft. – 2 ft. tall. It spreads faster, its foliage is grayer, and a little wider and lobed mostly at the end.
How to Grow Artemisia
Zones: 4-9, Full sun; average garden soil, with good drainage, keep on the dry side.
Deer resistant. Give them room.
Harvesting Artemisia Foliage
Cut the stem as far down as you can go. Put into water to work with them in fresh bouquets, condition as usual.
To work with dried artemisia foliage, let the stems dry by hanging or by laying them flat. If they get too dry you may need to wait for moist weather to let them become more flexible. Or let them dry till they’re still pliable but won’t flop when they’re in an arrangement.
If you live in a damp climate, the foliage may flop on you. So you may need to work the stems into flowers that will support them to stay upright.
My Favorite Variety
‘Silver King’ is my favorite because of its lobed foliage and silvery color and its height.
