some think the Katsura tree smells like caramel or cotton candy when it loses it's leaves in the fall. Besides being wonderful to smell in the fall, the Katsura sports a lovely blend of orange-, raspberry- and apricot-coloured leaves. In the spring Katsura has reddish-purple new growth, in summer it sports heart-shaped blue-green leaves and in winter the gray, slightly exfoliating bark lends interest.
