This is the perennial honesty, a lovely plant for the shady garden. It grows to two or three foot tall (60cm - 90cm) and it has large heart shaped apple green leaves in spring turning mid green as summer arrives. Clusters of scented white flowers with a lilac wash are borne in clusters in late spring and early summer. These are followed by eliptical papery seed heads that remain on the plant throughout winter. Although it does self seed, it has yet to do so in my garden. In this regard it is therefore less aggressive than the common biennial purple flowered variety. Site the plant close to a doorway or path to enjoy the sweet scent on a warm early summer evening. See and smell the plant in all its glory in the Mairi garden at Mount Stewart in late April and early May.
