Banana shrub

The Canberra card pairs its favorable label with a description of a dense shrub used for hedging. In the Canberra Plant Selector’s August 25, 2026 capture, Port Wine Magnolia (Michelia figo) is an evergreen shrub for screening, hedging and ornamental planting. Its card marks Fire Retardant “Yes” while describing a plant 2–4 meters tall and 2–3 meters wide. That is a regional selection attribute alongside a horticultural profile, not an assurance that a continuous hedge beside a building has been assessed.

The historical Eastern United States selector gives the same species an At Risk (3) grade and records ladder potential “Yes” without pruning. It assigns Landscape Zone 2, the area 5–10 feet from a house in that program. Its zone guidance combines a well-kept lawn with fuel breaks such as stone paths, walls and patios, and warns against easily ignitable, fast-burning evergreens. The At Risk grade and unpruned-ladder warning both belong to the historical selector; its zone number does not cancel them.

Plant size makes those conditions consequential. The Eastern row gives a mature height of 10 feet, separately printed as 3 meters. Its general guidance calls for at least 2 feet between fully grown vegetation and a structure, removal of dead leaves and twigs, and pruning of dead, diseased and low branches. The selector’s general guidance also advises avoiding close mass planting. A hedge-use label alone therefore cannot settle the spacing and maintenance question. The program’s separate tree-clearance figures should not be turned into a pruning height for this shrub.

Even the growing conditions need their source names attached. Canberra specifies partial shade, medium watering and moist, well-drained soil; the Eastern row specifies full sun, low drought resistance and low tolerance of poorly drained soil. Reading the Canberra and Eastern U.S. guidance together leaves a practical distinction: choosing banana shrub for a screen and evaluating that screen’s fuel connections are separate decisions.
