Achillea filipendulina 'Cloth of Gold' is a robust Hardy Herbaceous Perennial. It represents the highest hardiness rating in the British Isles (H7), capable of withstanding temperatures below -20°C. Biologically, it is an architectural specialist, possessing tall (1.5m), fibrous stems and deeply pinnatifid, feathery foliage that is highly efficient at capturing moisture in arid conditions.

The "Gold" Biology: Each flower plate is a complex cyme composed of hundreds of minute florets. This variety is valued for its rigid structure; the stems are engineered to support the heavy, horizontal floral plates without the need for staking, provided the plant is grown in the full-sun conditions it requires.

Pollinator Support: As an RHS Plant for Pollinators, 'Cloth of Gold' is a high-frequency nectar source. Its flat "landing pads" are an exceptional resource for larger British pollinators, particularly butterflies and hoverflies. These beneficial insects provide natural pest control, predating on aphids throughout the summer months.

Achillea seeds require specific light conditions to break dormancy and ensure uniform germination.

How to Sow:
Sow indoors from February to April, or in September/October to overwinter. Surface sow the seeds onto moist, high-quality seed compost and do not cover them; Achillea seeds are photoblastic and require light to trigger germination. Simply press them gently into the surface to ensure contact. Maintain a consistent temperature of 18-20°C. Germination is reliable and typically occurs within 7-21 days.

Where to Plant:
They demand full sun and thrive in well-drained soil. Lean soil is critical; avoid over-fertilising with rich manure, as high nitrogen levels will encourage weak, floppy growth at the expense of the architectural flower plates. Space plants 45cm apart to allow for their statuesque architecture. They are highly drought-tolerant once established.

Ongoing Care:
Keep the soil moist until established. To maintain a continuous display, remove the faded golden plates; this signals the plant to produce a second wave of blooms in late summer. For a structural winter aesthetic, leave the final flower heads standing; they look spectacular when touched by frost and provide a professional-grade "everlasting" material for dried floral design.

The golden plates of 'Cloth of Gold' work spectacularly with architectural partners from our range:

• 🔵 Globe Thistle (Echinops): The Geometry Contrast. A high-impact, professional-looking combination. The metallic blue spheres of Echinops float beautifully next to the flat golden plates of the Yarrow, creating a sophisticated structural display that is irresistible to bees.
• 💜 Salvia 'Violet Queen': The Royal Pair. For a sophisticated aesthetic, pair the horizontal golden plates with the vertical purple spikes of Salvia. The two species share an identical love of sun and drainage, providing a professional-grade layered border that remains structural well into winter.

Surface sow in spring or autumn for a summer-long harvest of golden flower plates that will return faithfully to your borders year after year.
