Polygala myrtifolia 'Grandiflora' (Sweet Pea Shrub) - A large dense evergreen shrub that grows to 10 feet or more tall by an equal spread. The unique rich purple flowers have two winged petals that surround the whitish purple lacy crest. They bloom during most of the year, spring is their peak bloom period. Plant in sun or part shade with regular watering. Polygala myrtifolia is one of the parents of the popular Polygala x dalmaisiana (the other parent is Polygala oppositifolia) from which it differs by being a bigger plant with larger brighter green foliage and larger flowers. The form 'Grandiflora' is reportedly the large flower selection although we have never seen the straight species. The name Polygala is Latin from the Greek word 'polugalon' for "much milk" because of the belief that cows grazing on milkwort increased their milk production.  The information about Polygala myrtifolia 'Grandiflora' displayed on this page is based on research conducted in our nursery library and from online sources we consider reliable.
