About this cultivar:
Knautia arvensis(previously called Scabiosa rumelica) has blue-violet, pincushion-like flowers held high on slender, branched stems. The specific epithet is Latin, meaning "of cultivated land" which likely means it grows along roadsides, in disturbed areas, and in fields.
Like its Macedonian cousin this popular, airy, wild-flower-ish perennial brings long-lasting colour to the garden and attracts all sorts of butterflies and bees. Don't prune the seedheads; they look great and feed the birds. Great through anything (Roses?). I have read that it is good at the back of the border but I also like it at the front, where you notice it!

About this genus:
Knautia (naughty-a) is a genus in the honeysuckle family (Caprifoliaceae). The common names of these flowers are a variant of "widow flower." Others are given the name "Scabious," although this word belongs to a related genus (Scabiosa).The name Knautia comes from the 17th-century German botanists, Drs. Christoph and Christian Knaut.
Most of the cultivars we have are perennial - and they really are! (we've seen some annuals sold as perennials). They do best in full sun but will tolerate some shade. Soil wise, almost anything that isn't waterlogged will be fine. These plants can vary in size depending on the season, so watch out - it might flop over! Never-the-less people who visit our garden just love love love this genus of plants, it really has popular appeal.
We have a few different colours and cultivars growing around the garden and we plant them through a variety of plants like Monarda, Stachys, Perovskia, Molinia, and Penstomen. Although we also grow a few species on their own near the edge of the garden for a big, bushy, airy, wildflower-ish effect.
