Design IdeasA highbrow perennial rooted in the traditional cottage garden. It belongs in every romantic composition, particularly country gardens. Indispensable to highbrow English perennial borders. Incredible massed into large landscapes. Demanding little surface area while offering tall staffs of color, this plant is a problem solver in spatially challenging urban gardens. Excellent in naturalistic plantings around edges of woodlands and meadows as a quasi-wildflower. Charming in red clay pots and other decorative containers on porch, patio, balcony and roof garden. A cutting garden essential.
