Answer: Without photos, you should be able to tell them apart without too much trouble. The Prunus cistena is a shrubby small tree (only to about eight feet tall) with purple/red foliage. The Cercis canadensis is a redbud tree, it blooms by showing tiny pink buds and flowers all along the bare branches in early spring before it leafs out. The foliage is green, leaves are fairly large and heart shaped. Redwoods have needles. (I am not sure what a transparent redwood would be, there is a wood stain called by that name.) You can find some photos at the Monrovia web site where the catalog is searchable. Enjoy your new home and yard!
