Hieracium caespitosum
Yellow Hawkweed
Hieracium - hawkweeds - are perennials, usually with a tap root, basal rosette of leaves (sometimes toothed) and dandelion-like, yellow flowers in Summer. They can be invasive.'Yellow Hawkweed' sports dandelion-like flowers which form a tight, flattened cluster at the tip of a long stem. Individual flowers are about 2cm across, with dense, dark glandular hairs on the bracts and short flower stalks. The flowers stay in a broad compact cluster through the bloom period. It is stoloniferous and invasive.

Flowering
From Early Summer TO Mid Autumn
Hawkweed flowers from early Summer to first frosts or mid Autumn
Planting
From Early Spring TO Mid Spring
If planting hawkweed, choose a sunny site in free-draining soil. Bear in mind that some types of hawkweed can be invasive, and self-seed freely.
Propagating
From Early Spring TO Mid Spring
Hawkweed is a vigorous self-seeder, and, once established, will spread seed freely. Getting rid of it may be more of a problem than getting it to reproduce! It can, however - if desired - be grown from seed in Spring by scattering seed in the desired site - in free-draining soil, and in full sun or partial shade.
