Can anyone recommend an easy to grow, low maintenance evergreen shrub for a half barrel container, ideally that attracts bees, etc?
They are moderately frost hardy, Grow them in any well-drained soil in sun or light shade. You can propagate from cuttings in the summer or from seed in autumn.
Propagate by simple layering in the autumn, by cuttings (softwood for deciduous species, semi-ripe for evergreens) in summer, hardwood cuttings in the winter or by seed in autumn.
