Not all early spring blooming trees are regarded as ornamental, such as red maples or birches, but still their flowers provide visual interest and some color. Large shrubs that have a tree-like form also provide excellent early spring flower color.
Group 1 is the early flowering species which generally bloom in late April to late May. These include Clematis alpina 'Constance', Clematis alpina 'Pamela Jackman', Clematis macropetala 'Lagoon' (nice deep blue with double petals) and Clematis montana 'Elizabeth'.The Group 1 clematis bloom on last year's wood.hese require minimal pruning to remove any dead stems in late March just as buds swell. These include 'The President' a nice rich purple or 'Vino' a deep red. 'Mrs. Cholmondeley' is light lavender blue and seems to tolerate more shade than other clematis.
