Yarrow Parkers Varietät

Divide the care into two phases:

• After planting: Keep the soil slightly moist until the plant fully roots (the first few weeks). Water less often but thoroughly.
• Adult plant: Yarrow Achillea filipendulina is relatively drought-tolerant. Water only during periods of prolonged drought and heat. Waterlogging is more dangerous for it than short-term drought.

Acclimatization is key. If the seedlings arrived by mail or you brought them from a protected nursery, do not expose them to the midday sun immediately.

1. Unpack the seedlings and check the moisture of the substrate.
2. If the root ball is dry, submerge it in water for a while.
3. Leave them outside in the shade or partial shade for 1–2 days to get used to the outdoor climate.
4. Then plant them in their permanent location.

This type of Yarrow is a sun lover. Choose a fully sunny spot for it – in the shade, the stems would stretch and flowering would be weak. Regarding soil:

• It must be well-drained (drainage is essential, roots rot in the wet).
• It should be well-supplied with nutrients, but not over-fertilized with nitrogen.
• It tolerates even stony and drier soils after rooting.

You can plant seedlings of this Yarrow in the spring (as soon as the risk of strong frosts has passed, usually from April to May) or in the autumn (September to October). It is important that the plant manages to take root before the summer heat or, conversely, the winter frosts arrive. If planting in summer, very careful and regular watering is necessary.

Yarrow (Achillea) contains substances (alkaloids, glycosides) that are mildly toxic to dogs, cats, and horses if ingested in large quantities (can cause vomiting, diarrhea). It is not dangerous to humans, but in sensitive individuals, contact of the leaves with the skin combined with the sun can trigger a phototoxic reaction (rash). We recommend using gloves when working with the plant.

You have two great options:

1. For repeated flowering: If you cut back the spent stems soon after flowering (during the summer), you will encourage the plant to produce new flowers and extend the season.
2. For winter effect: If you let the inflorescences dry on the plant, you will gain a wonderful winter structure. The large flat flower heads look breathtaking when covered in frost or snow.

It is not strictly necessary if you have quality soil. Yarrow is modest. It is enough to add a little mature compost to the clump in the spring. Avoid fertilizers with a high nitrogen content – these would cause lush leaf growth at the expense of flowers, and the stems would be weak and break.

It is a hardy plant, but occasionally the following may occur:

• Aphids: They like to suck on young shoots. They can be washed off with a stream of water or treated with a soapy solution.
• Powdery mildew (white mold): Appears if the plant is in too much shade, a poorly ventilated space, or suffers from drought at the roots. Prevention involves choosing the right location and watering directly to the roots, not on the leaves.

The 'Parker's Variety' cultivar is a robust perennial that grows to a height of 100 to 120 cm. Thanks to its strong stems, it usually does not need support and holds its shape. However, if you grow it in a very windy place or in the shade (where it stretches), a gentle support (a circular support for perennials) may be appropriate to prevent the clump from flopping over.

Yes, it is one of the best perennials for this purpose!

• For the vase: It stays fresh for up to 10 days. Change the water regularly; the stems tend to foul the water quickly.
• For drying: Harvest fully opened flowers (when pollen is visible) during dry weather. Tie them into bunches and dry them hanging upside down in a dark, airy place. It retains its yellow color beautifully.

Although it is related to the medicinal common Yarrow (Achillea millefolium), the species Achillea filipendulina is grown primarily for ornamental purposes. While it has a typical bitter aroma, it is not commonly used in the kitchen or home medicine cabinet. We recommend enjoying its flowers visually instead.

Fernleaf Yarrow is fully frost-hardy. If you left the stems over winter for decoration, cut them back early in the spring just above the ground (before new leaves start sprouting). If you already cut them in the autumn, just clean the bed of old leaf debris in the spring. No special covering is usually needed.

Definitely! Its flat inflorescences serve as an ideal landing pad for insects. It attracts bees, bumblebees, butterflies, and also hoverflies, whose larvae feed on aphids. It is therefore a very useful plant for ecological balance in the garden.

Yes, Yarrow grows in clumps that expand over time, and the center may start to become woody and bloom less. We recommend dividing the clumps every 3 to 4 years. Do this early in spring or in autumn. Dig up the clump, divide it into smaller parts with a spade, and replant them. This rejuvenates the plant and boosts vitality.

Thanks to its large flat yellow flowers, it forms a great contrast to plants with vertical inflorescences. It looks excellent with:

• Woodland sage (Salvia nemorosa) – blue contrast
• Larkspur (Delphinium)
• Coneflower (Echinacea)
• Ornamental grasses (e.g., Miscanthus or Calamagrostis), which add lightness.
