Nursery contributed plant descriptions

Promising new selection from Lady Cynthia Postan at Cambridge University, England. This ceanothus resembles the form of 'Concha' (though in our experience a slower grower) and the flowers of 'Wheeler Canyon'. The small, glossy dark-green leaves cloak upright, spreading branches and rich blue, subtly sweet blooms open from magenta buds to dust the entire shrub through the spring. Mature plants reach a manageable height and width of 6-8' making this an ideal choice for urban and suburban landscapes. Hardy to 10F.
