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.
