Plant Phenology: Guilford CT, 2003
Abstract:
Vegetative development and flowering of 23 plant species in a horticultural setting were evaluated weekly from March to July 2003. Plants included crocus, daffodil, tulip, iris, bleeding heart, lambs ears, creeping phlox, lavender, artemisia, coreopsis, rose, dwarf spruce, forsythia, rhododendron, cherry, dogwood, lilac (Syringa chinensis), mountain laurel (Kalmia latifolia), Virginia creeper (Parthenocissus quinquefolia), hackberry (Celtis occidentalis), shadbush (Amelanchier sp.), sugar maple (Acer saccharum), and Norway maple (Acer platanoides). 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).
