                            Hazardia squarrosa is an evergreen shrub that can reach heights of up to 2m. It is native to North America and is found in temperate regions. Propagation is best done from cuttings taken in spring or summer. Cuttings should be taken from the tips of the branches and should be about 10cm long. The cuttings should be placed in a well-draining potting mix and kept moist. Once the cuttings have taken root, they can be transplanted into the garden.
