Family: Wallangara White Gum
Over the last 10 years, many public plantings of E. scoparia have been developed. Horticulturists have developed these plantings because of the relatively fast growth of E. scoparia, its somewhat small size at maturity, its broad spreading crown, and its extremely attractive white bark. In some areas, these plantings have not been highly-regarded, mainly because E. scoparia has been broader and more open-crowned than those selecting the trees required. E. scoparia is not a ‘replacement’ for exotics or very small Australian trees such as E. leucoxylon ssp. megalocarpa; instead it is a mid-sized tree that can be best used on broad streets, in avenues or in parks.
E. scoparia originates on very dry, gravelly soils along the border between Queensland and NSW. It is highly tolerant of dry, hot conditions, and will tolerate most urban compaction well. The foliage is lush, but the shade is not dense as the crown is quite spreading. In Melbourne, this White Gum will tolerate most conditions, although there are no data to support its tolerance to waterlogging.
E. scoparia is somewhat troubled by lerps in Melbourne, although not as much as E. botryoides. It can also be infested lightly with Scale insects and Sooty Mold. On mature trees, this lerp damage is not noticeable; on young trees, the blistered leaves can be removed manually.
If used correctly, E. scoparia can be an excellent tree, and may be used as a considered replacement when E. viminalis is too large for the site.
