A highly ornamental native shrub to small tree to 7 meters tall and half the spread. Rarely grows straight, but takes on the multistemmed arching sinuous form. Serrated lobed leaves are a nice green but fall colour varies as its more red in sunny sites and yellow in shade.
Germination cut testing result: 50%. This maple tolerates almost any growing site; from dry to moist and almost well draining soil type. Essentially, its just happy to be there. Used in land reclaimation as it is very drought tolerant. Dewinged seed.
Will be cold moist stored as all Acer seed lose viability when dry. Place seed in tepid water, sow the sinkers immediately. Soak floating seed 12-24 hours until it sinks and sow immediately. Sow thinly at 6 mm deep in a sandy peat layer; tamp firm. Cold strafify for 60-120 days. Keep moist. Add a thin layer of fine mulch. Don't let germinating seed freeze, dry out or migrate onto the medium surface as this is fatal. After cold stratification period is over, expose to Spring conditions to promote germination. Good indirect light is best for seedlings. Protect seed/seedlings from varmits. I prick out seedlings when dormant and grow in individual pots for first 2-3 years for best results.
