Has long, lance shaped, mid-green leaves. Bears tubular, bluish-deep purple flowers borne over summer.
Flowers June - September
Loves a well drained soil in sun or light shade. Isn't very hardy so bring inside before it gets really cold or mulch heavily in milder climates.
Sometimes P. 'Stapleford Gem' is sold as 'Sour Grapes', 'Stapleford Gem' has whitish lower lobes. |
