Campestre Colchicum Rubrum, with its bright crimson palmate leaves,
is very ornamental, as is also Negundo Californicum Aurem, with its
golden-yellow foliage. The Maple grows best in a sandy loam. It may be
increased by cuttings planted in a shaded situation, or by layers, but
the choice varieties are best raised from seed sown as soon as it is
ripe.

while in a growing state. Height, 6 in. to 2-1/2 ft.
