Yarrow Red Velvet

Yarrow 'Red Velvet' is a drought-loving plant. Adult plants generally do not need additional watering and can get by with rainfall. Water only in case of extreme and prolonged drought when the plant begins to wilt. Excessive watering harms it more than drought.

Container-grown seedlings can be planted throughout the growing season (from spring to autumn) as long as the ground is not frozen. However, the most suitable times are:

• Spring (April–May): The plant has the whole season to establish.
• Autumn (September–October): The soil is warm and moist, which encourages root growth before winter.

Mostly, fertilization is not necessary, and can even be counterproductive. In soil that is too rich, Yarrow tends to produce a lot of foliage, but the stems are soft and the flowers sparse. It is enough to add a little well-rotted compost to the plant in spring. Avoid fertilizers with high nitrogen content.

To maintain the plant's beauty and vitality, we recommend cutting back after the first flush of flowers:

• Remove spent stems just above the ground or above the clump of leaves.
• This cut encourages the formation of new buds, and the plant often blooms a second time in late summer or autumn.
• At the same time, you prevent the plant from exhausting itself by producing seeds.

Although adult Yarrow is very drought-tolerant, a freshly planted seedling needs care until it establishes:

1. Water the plant thoroughly after planting.
2. In the first few weeks, keep the soil slightly moist (not waterlogged) so the root ball does not dry out.
3. Once the plant establishes and starts forming new leaves, limit watering only to periods of prolonged drought.

Common Yarrow (Achillea millefolium) is slightly toxic to dogs, cats, and horses if ingested in large quantities (it contains glycosides and essential oils). It can cause vomiting or diarrhea. In sensitive people, contact of leaves with skin combined with sunlight can trigger skin irritation (photosensitivity). We recommend using gloves when handling larger quantities of plants.

Achillea millefolium is a native wild perennial and is fully frost-hardy in our conditions. It requires no special winter protection. In autumn or early spring, simply remove the dry above-ground parts of the plant. If you plant late in autumn, you can mound a little mulch or brushwood around the roots to prevent frost from heaving the seedling out of the soil.

Yes, Yarrow is one of the best perennials for drying. The flowers retain their shape and a large part of their rich color even after drying. For drying, cut the stems in full bloom, tie them into smaller bunches, and hang them upside down by the inflorescences in a dark and airy place.

Yarrow spreads via underground runners and forms clumps. The 'Red Velvet' cultivar is vigorous but less aggressive than the original wild species. Nevertheless, it will spread sideways over time. If you want to limit its spread, simply chop off the edge parts of the clump that are growing out of the designated space with a spade in spring.

Although Achillea millefolium is a known medicinal plant, the 'Red Velvet' cultivar was bred primarily for ornamental purposes – for flower color and habit. The content of active substances may differ from the wild form. For herbal harvesting and medicinal purposes (teas, tinctures), we recommend using the original, white-flowering wild species.

Stem flopping in Yarrow 'Red Velvet' usually has two main causes:

1. Lack of sun: The plant stretches for light and the stems are weak.
2. Soil that is too rich or over-fertilized: Excess nutrients cause rapid but soft growth.

Solution: Transplanting to a sunnier and poorer site or a radical cutback in mid-June (the so-called Chelsea chop), which strengthens the plant and delays flowering.

Yarrow is very undemanding and prefers poorer, drier, and well-drained soil. It thrives in loam-sandy or gravelly soils.

What to avoid:

• Heavy clay soils that retain water (roots could rot).
• Soils that are too rich and over-fertilized (the plant would grow too vigorously at the expense of flowers and stem strength).

Thanks to its deep red color and flat inflorescences, it creates a beautiful contrast with plants of other shapes. Great companions are:

• Ornamental grasses (e.g., Stipa, Pennisetum)
• Coneflowers (Echinacea) and Rudbeckia
• Salvias (Salvia nemorosa)
• Monarda It fits well into so-called prairie plantings and natural gardens.

To keep the Yarrow blooming profusely and prevent the center of the clump from becoming bare, it is recommended to divide the plant every 3 to 4 years. Do this early in spring or in autumn. Dig up the entire clump, divide it with a spade into smaller parts, and replant the strong, healthy seedlings. This gives the plant new energy.

Yes, it is excellent for cutting. Thanks to its long and sturdy stems, it is perfect for bouquets. It lasts fresh in a vase for approximately 10 days. Harvest it when the tiny flowers in the cluster are fully open so it does not wilt prematurely.

Yarrow is a very healthy plant, but in unsuitable conditions, the following may appear:

• Powdery mildew (white mold on leaves): Occurs if the plant is in shade, in excessive humidity, or lacks air circulation. Prevention includes a sunny site and sufficient spacing between plants.
• Aphids: Can occasionally attack young shoots, but usually do not significantly harm the plant.

Choose a fully sunny site for Yarrow 'Red Velvet'. This perennial loves sun and heat. In the shade, the plant would stretch its stems, which would be weak and flop over, plus it would flower less. It is ideal for south-facing beds, rock gardens, or gravel gardens.
