Sweet Gum (Liquidambar styraciflua)

Sweet gum is really nice garden tree, because its variation of its colour can bring fresh and new feeling to people. In earlier spring, the leaves of sweet gum are cool green and in October, it will turn orange or yellow, but the colour is maybe distinctive with PH of soils. A appropriate soil condition is recommended that is in lime-free or acid soils(A Garden Tree Nursery, 2010)

Sweet Gum is 18m in the height, and 12m across.Its crown looks like long conical: its leaves are like star shape with jagged lobes.. Interestingly, sweet gum’s twig smells a little bit scented, which is a advantageous reason as a lovely garden tree. Buds is a little reddish in earlier spring, so it is different from other tree .and its fruit  looks like a ball with many thorns.

Sweet gum is frequently found on riverbank, because here it can get full sunlight and moist  soils. It has the tolerance of a wide range of conditions, but in lime-free and acid soils would be better.

There is a wide space under sweet gum, so annual wild flowers can be planted around it, which can provide a vibrant contrast in the garden, thus it is suitable in a large garden rather than a small yard.

It is approximately 40-120cm high. From June to July it begins to bloom. Its long and pliable spikelet consists of several sharp florets.

Seeds of upright brome is 9-11mm long excluding awn, 1.5mm wide, and 1-1.2mm thick(Agriculture and Consumer Protection, 2004).
