Dawn redwood vs. Bald Cypress
The dawn redwood is a fast grower compared to the bald cypress’ slow rate of growth. The foliage of the dawn redwood is arranged oppositely, in that he leaves come out on exact opposite sides of the stem. In the bald cypress, they are seen to be in an alternate arrangement, meaning if there is a leaf-shoot on one side of the stem there will not be any on the opposite side, and instead will be a little above or below.
