Lamprocapnos spectabilis

Plant in well-drained soil improved with organic matter, in a spot that gets sun or light shade; it’s more tolerant than Lamprocapnos species, so it will cope well with a brighter position as long as the soil doesn’t dry out completely. Water during prolonged dry spells, especially while it’s establishing, but avoid overly wet conditions.

Deadhead spent flowers regularly to keep new blooms coming, and trim back lightly if it starts to look untidy through the season. Unlike older cultivated varieties, it won’t die back early, so leave the foliage in place and simply cut it down in late autumn or early spring, finishing with a mulch of compost to keep it healthy year to year.
