  • Posted by SongofJoy (Clarksville, TN - Zone 6b) on Mar 19, 2012 4:42 AM concerning plant:
    Alyogyne huegelii is a loosely open shrub growing up to about 6 ft tall and of almost equal width. It has lilac-colored, hibiscus-like flowers. The plant can produce hundreds of 3-4" blooms each season. The flowers last 1-2 days.

    The variable lobed leaves are dull green and the foliage is attractive when pruned to keep it compact. After the main flowering flush in late spring the shrub can be pruned back quite hard to ensure stronger growth and increase its longevity and flowering life.

    With appropriate pruning it can be maintained as a small compact shrub or trained into a standard.

    This plant is moderately frost-tolerant.
