Cottonwood Poplar and Birch add subtle autumn shadings to damp areas and are ideally suited to a wide range of climates and conditions.
Sugar Maple (Acer saccharum), is one of the most beautiful, reliable and vivid trees for colourful autumn foliage. These hardy and most worthy trees grow best in colder climates.
Birch and Cottonwood Poplar usually produce subtle yellow shadings combining with architectural trunks that are well suited to moist situations and tolerate wide environmental extremes.
Crepe Myrtle (Lagerstroemia) adds a variety of vivid waxy leaves to the autumn show. Over a long period, leaves change from green to charteuse, yellow and gold, to flaming orange/ red shades then brick brown and burgandy before they fall to reveal lovely polished bark.
Larix (Larch) pictured here, and Taxodium (Bald Cypress) are very durable and hardy deciduous conifers. They are best suited to moist locations. Both feature feathery foliage with distinctive russet autumnal tonings. Taxodium prefers warmer climates growing well in the subtropics. Larch is ideal for colder zones up to the Arctic Circle.
Deciduous Oak (Quercus) species, like this Northern Red Oak often feature bright bronze, brick red, scarlet and russet autumnal shades that sometimes last into the early days of winter.
Autumnal subtropcial garden displays often resemble summer gardens found in colder temperate climates.
Crepe Myrtle (Lagerstroemia) in its full autumnal blaze. Leaves once they fall are a rich source of compost while bare branches allow winter sun to warm the earth below.
Liquidamber (Aurora Sweet Gum), is adaptable to large containers, plus many garden and landscape situations. Aurora produces reliable and spectacular autumnal color. First colorful leaves herald the beginning of Autumn. Winter often begins as the last Liquidamber and Oak leaves fall.
New Zealand's remarkable subtropical zones can support cold weather natives like Liquidamber, Red Twig Dogwood or Red Osier (Cornus stolonifera) and conifers like Governor Cypress growing next to Citrus like these Tangelo creating unusal autumnal displays.
The only hint that this is an autumnal scene are the seed pods of Japanese Iris (foreground).This is a mid-autumn display in New Zealand's subtropical "winterless" north.
