Plant Phenology: Kittery Point ME, 2004-2008
Vegetative development and flowering of 20 plant species in a horticultural/woodlot setting were evaluated weekly during the growing season from 2004 to 2008. Plants included snowdrops, crocus, daffodil, tulip, bleeding heart, forsythia, rhododendron, dwarf weeping cherry, crabapple, magnolia, basket willow, wisteria, climbing hydrangea, mountain laurel, cornelian cherry (Cornus mas), lilac (Syringa chinensis), shadbush (Amelanchier sp.), sugar maple (Acer saccharum), black oak (Quercus velutina), and white birch (Betula papyrifera). Each plant was rated on a scale from 0 to 4 for vegetative development (0 = no growth or unexpanded buds;... 4 = leaves fully expanded) and for flower conditions (0 = no flowers or no expanding flower buds;... 4 = peak flowering, one half or more flowers open).
