Artemisia ludoviciana

Artemisia ludoviciana is a child of the sun. Choose a fully sunny location for it. In shade, it will lose its beautiful silvery color, turn green, and the stems will be weak and leggy. Do not be afraid of places with all-day scorching sun; south-facing slopes or rock gardens are ideal for it.

Less is more in this case. Artemisia ludoviciana loves poor, permeable, sandy to stony soils.

• Avoid: Heavy, clay, and wet soils where its roots would rot.
• Tip: If you have heavy soil in your garden, lighten it before planting with a large amount of sand or fine gravel.

Yes, Artemisia ludoviciana spreads using underground rhizomes and can behave invasively if conditions are ideal.

How to keep it in check:

• Grow it in containers sunk into the ground.
• Use root barriers when planting.
• Or reserve a space for it where its wild growth won't matter (e.g., natural parts of the garden).

You can plant mugwort seedlings from spring to early autumn. The most suitable time is mid-May (after the "Ice Saints"), when the soil is already warmed up.

Planting procedure:

1. If you received the seedling by mail or kept it indoors, let it acclimate outside in the shade for a few days to get used to outdoor temperatures and the sun.
2. Dig a hole slightly larger than the root ball.
3. We recommend putting a layer of gravel or pebbles at the bottom of the hole for drainage.
4. Plant the seedling at the same depth as it was in the pot.

This is an extremely drought-tolerant plant. Once established (after the first year), it practically needs no watering and relies on rainfall. Water only during periods of extreme, prolonged drought. Remember that waterlogging is much more dangerous for wormwood than drought.

Pruning is important for maintaining a compact shape:

• Spring pruning: Early in spring (March/April), cut the whole plant down low above the ground (approx. 5–10 cm). This supports dense growth.
• Summer pruning: If the plant starts to sprawl or after flowering, you can trim it back by roughly half. It will quickly sprout silver leaves again.

It tends to be very resilient. Thanks to its aroma, it repels most pests. Occasionally, aphids may appear. The most common problem is fungal diseases (root rot, powdery mildew) caused by poor location – too much moisture or lack of air circulation.

No, fertilizing is not recommended for this species. In soil that is too nutritious or when fertilizers are used, the mugwort grows too vigorously, its stems are soft, do not hold their shape, and tend to "wallow" on the ground. In poor soil, the plant will be more compact and healthier.

Thanks to its silver color, it forms a beautiful contrast with dark-leaved or colorful flowering perennials. It fits well in xeriscape beds and gravel gardens.

Great neighbors:

• Coneflower (Echinacea)
• Salvia
• Lavender
• Ornamental grasses
• Stonecrops (Sedum)

It is an excellent plant for florists. It lasts 5 to 7 days fresh in a vase. For drying, harvest stems at the beginning of flowering or just before, when the foliage is nicest. Dry by hanging in bunches upside down in a dark and airy place. The silver color of the leaves remains preserved even after drying, which is great for wreaths and winter decorations.

Silver wormwood isn't highly poisonous, but it contains substances (including thujone) that can be toxic in large quantities. The plant is very bitter, so animals usually don't eat it.

• For dogs and cats: Ingesting large amounts can cause vomiting or diarrhea.
• For humans: Not intended for consumption as a vegetable. Handling may cause skin irritation (contact dermatitis) in sensitive individuals, so we recommend gloves.

In the first weeks after planting, regular watering is key until the plant roots thoroughly. The soil should be slightly moist but never soaked. Once the mugwort roots (you can tell by new growth), reduce watering significantly. This plant is used to drought and excessive care rather harms it.

Yes, it is fully frost-hardy (handles temperatures down to -28 °C or less).

• Winter care: The problem in winter isn't frost, but winter wetness. Ensure the plant isn't standing in a depression where water accumulates.
• Pruning: Do not remove the above-ground part for winter; it protects the roots. Cut back dry stems only in spring.

Unlike tarragon (Artemisia dracunculus), this species is not used in the kitchen due to extreme bitterness.

• Folk use: Historically used by Native Americans for ritual purposes (smudging) and as a medicinal plant for various ailments. Today, it is used primarily as an ornamental plant or in aromatic mixtures (potpourri).

This problem usually has three causes:

1. Lack of sun: The plant stretches towards the light.
2. Soil too rich: Excess nitrogen causes rapid but weak growth.
3. Too much water: The plant is 'bloated' and tissues don't lignify (harden).

The solution is transplanting to a sunnier and poorer site or a radical cutback.
