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 provided on this webpage is based on the research that we have conducted about this plant in our nursery library and that information that we have found about it on reliable online sources. We also take into consideration observations in our nursery of crops of this plant, as well as of plants growing in the nursery's garden and those in other gardens. We will incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information aiding others in growing Polygala myrtifolia 'Grandiflora'.
