From late spring, right through to early autumn, whorls of hooded, pale yellow flowers appear at intervals on tall, erect stems with dramatic, heart-shaped leaves. A vigorous, spreading perennial that's justifiably popular, due to its long flowering season and tolerance of drought. It looks great in a mixed border, but it needs room to express itself. The flowers are also worth leaving on in winter as they look magical when covered in frost.
- Garden care: In mid-spring shorten any frost-damaged stems, cutting back to just above a healthy bud. Remove any weak or diseased shoots, cutting cleanly back to the base.
