1 Identifying Plants in Winter Slides 1-5: Reference: 1 By Charlie Dubay Workshop presented to John Clayton Chapter, VNPS on 2/18/12

2 2 SOME WAYS WE IDENTIFY WOODY PLANTS IN WINTER 1.Old leaves (on ground or dried on the tree) 2.Buds (number/shape/color) 3.Twig ( color/rough/smooth/fat/thin/thorns/zig-zag ) 4.Twig odor when scratched 5.Leaf/bud/twig attachment (opposite/alternate) 6.Leaf type ( scale/needle/broad/compound/simple ) 7.Leaf scar (shape/bud position/bundle scars) 8.Evergreen or deciduous 9.Bark (rough/smooth/color/lower branches) 10. Fruits (dried or ripe on tree or on ground) 11. Habitat (wet/dry/shade/sun/slope/flat) 12. Plant growth form (vine/shrub/tree)
