What do these mean?



‘Concha’ is one of the oldest of the many available ceanothus hybrids. It was discovered in a garden in the 1940’s, a chance hybrid between C. impressus and C papillosus. The form is upright and rounded, with arching branches of narrow, oval leaves. ‘Concha’ is covered in early spring with large dark blue, almost purple flowers. The flower buds are magenta, making for quite a display against the dark green foliage. The height will vary somewhat with growing conditions, but a final height of eight feet is a safe assumption. This hybrid is quite hardy and long-lived. Like all ceanothus, ‘Concha’ thrives on neglect once established, i.e. no supplemental irrigation.
