Ferns are fine textured lacey-leaf groundcovers. Many kinds of ferns add a tropical accent to the shade garden.

Posted by Hugh on September 2nd, 2016
Most deciduous landscape trees drop their leaves sometime in autumn. The physiology of autumn leaf drop is primarily stimulated by changes in photoperiod or shorter daylength. Autumn colors develop and the leaf petioles form an abscission layer. Black gum (Nyssa sylvatica), for example, start to color up in early September. Winter leaf retention by […]
