Asteraceae: a tall perennial herbaceous plant to 1.3m. Found in wet woods, meadows and scrub by streams, swamps, moist grasslands, stream banks, grassy slopes and forest margins. The yellow, daisy flowers are held on branching stems, which contrast nicely against the black stems. Blooming from June- August. Large glossy round leaves to 30cm across. Native to Europe to Eastern Asia - China, Japan, and Himalayas.
The leaves can be cooked and eaten.
Best to surface sow seeds from Autumn to early spring. These perennial seeds germinate very irregularly over a long period. Lower temperatures of less than +5°C are very effective. Seed trays should not be discarded prematurely. Constant moisture must be maintained. Do not leave in direct sunlight. Prefers a deep moist or even boggy fertile humus-rich soil, succeeding in sun or semi-shade. Plants often wilt on bright windy days. The young growth in spring is very susceptible to damage by slugs and snails.
