A cloud of soft yellow flowers on a tall, well-branched inflorescence. Stems are thin and wiry but strong and self-supporting. No staking necessary.

I am astonished that such a tiny rosette of foliage can support so many flowers!

I've seen this in the gardens at Perennial Pleasures, East Hardwick VT Z4a, where it's a self-sowing biennial.

I agree completely, this plant deserves to be better known!
