Yarrows (botanical name: Achillea) are the workhorses of the summer perennial garden. They have a long bloom season and are tolerant of high temperatures and poor soils.
Here are some varieties growing at Dawn Gardens:
Achillea filipendulina is the tallest Yarrow and reaches 4 to 5’. It starts blooming in May and continues through July and August.
The flower turns brown in August but still keeps its structure. It is ornamental and is used for dried flower arrangements.
Here are some ground cover Yarrows that are also used for rock gardens:
Achillea tomentosa ‘Lemon’
Achillea lewesii ‘King Edward’
Woolly Yarrow (Achillea tomentosa)
Here is a clump of Woolly Yarrow growing along the edge of the road not planted, not maintained and not watered. It is a tough plant.
Here are some taller Yarrows:
Achillea ‘Moonshine’ 18”-2’
Achillea ‘Moon Dust’ 18”- 2’
Here is Achillea ‘Moon Dust’ cut back in July and watered deeply to encourage fall bloom.
Achillea ageratum ‘Moonwalker’
Achillea ‘Desert Eve Red’
