Achillea filipendulina 'Gold Plate' (Achillea)

Within the Achillea species there are many easily-grown and reliable species (around 85 in total).

History

Named after Achilles who is said to have discovered the plant's medicinal properties.

Originates from grasslands of the Northern hemisphere.

Planting

Can be planted at any point in the year. Water well before planting. Dig a hole loosening the soil with a fork, especially at the bottom. Place the plant in the hole so that the compost is at the same level as the surrounding soil. Fill in around the plant with loose soil and firm in the roots to secure the plant. Water again after planting.

Heavier clay soils should be loosened with grit and organic matter.

Propagation

Dividing the rootball in autumn or spring.

From seed - seeds can be grown in winter under cover in a cold greenhouse or coldframe. Or indoors in early spring and then directly into the ground after the last frosts have passed.

Self seeds quite freely on its own but you can also allow seedheads to dry on the plant, remove and collect seed, clean it and store for future use.

Cultivation

Will tolerate most soils and conditions but grows best in moist, well drained soil in an open site in full sun. Can be drought tolerant.

Aftercare

A reasonably easy plant to grow, requiring little attention, although it will need supporting before the flowerheads appear. Application of an annual dressing with a general fertiliser once a year is sufficient feed to keep the plant healthy. Dead heading will prolong flowering through the summer season. Seedheads should be removed if new seedlings are not required next season. Cut back the plant in autumn.

Pests

Mainly trouble free but may suffer from aphids.

Diseases

Trouble free.
