Spray paint is no way to get good autumn color in the garden. The healthy rich green king palm out front would look ridiculous and be very embarrassed, not to mention unable to breath, if it were painted yellow, orange and red, like the sweetgum trees that will soon be getting so colorful in the neighborhood now that the weather is getting cool.

Just like every other feature in the garden, autumn foliar color takes proper planning. Most of the plants with the most impressive autumn color happen to be substantial trees, so are not as easy to accommodate in as many situations as flowering annuals are. There are a few smaller shrubby plants and perennials that provide autumn foliar color, but almost all are deciduous, so defoliate to leave bare branches through winter.

Boston ivy (which is not really ivy) is probably the most colorful of climbing vines. It is a bit too aggressive for small spaces though, and damages painted surfaces and just about anything that it gets a hold of. It is best on concrete walls, which is why it is so prominent on freeway soundwalls and overpasses. Grapevine and wisteria are only moderately colorful.

Currant, crape myrtle, pomegranate, smoke tree and redbud are a few of the shrubby plants that provide good color in autumn. Crape myrtle and Eastern redbud are actually more commonly small trees. Many of the Japanese maples with good autumn color are small trees that stay smaller than most shrubbery.

Sweetgum, Chinese pistache, flowering pear and maidenhair tree are the best trees for autumn color, though maidenhair tree turns only bright yellow without the oranges and reds that the others get. Where well exposed, Japanese persimmon is comparable to Chinese pistache. Fruiting pear, apple, apricot, plum, prune and almond trees are not quite as colorful.

Several of the North American and European maples are remarkably colorful, but do not hold their foliage as long as sweetgum does. Silver maple and box elder (maple) happen to be less colorful than the other maples. Various poplars and locusts, as well as tulip tree and black walnut can almost get as bright yellow as maidenhair tree does.
