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 web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant. |
