Cultivation
Australian bluebells are generally easily propagated by division or root cutting. The seed is a very fine, black powder. It germinates readily in a few weeks and is best directly sown into tubes or cells as the seed and plant are very small and hard to separate and prick out.
There are a number of common cultivars, including various shades of blue from a saturated blue similar to #00f through to white. Various double forms are available. To maintain a cultivar propagation must be by vegetive means (division or cuttings).
Once established W. stricta is very hardy - the pot can be dried out completely and the plant reduced to a tuber, yet it will reshoot when the rain comes. It is hardy in a range of soils from sand to gravel, clay to humus.
