A vigorous rather than invasive plant that has been in British gardens since Victorian times.
It's very jolly and brightens up a moist spot in sun or shade.
Plants form a bushy, fast-spreading clump of green leaves, with loose spikes of bright-yellow starry flowers appearing in early to mid summer.
Easily lifted and divided when they outgrow their welcome but a useful plant that's not particularly fussy as long as the soil is damp.
