Polygala virgata 'Portola' (Purple broom) - A fast growing shrub up to 6 ft. tall, with long, narrow leaves and spikes of purple sweetpea-like blossoms. Tends to be very upright growing and bare at the base - best planted in groups to form an unusual but showy thicket. Tolerates dry conditions and frost once established. Sun or part shade. Root hardy to 10-15 F. Our current plants are a selection we made from crops that we originally grew from seed. To distinguish this selection from seedlings we have named it 'Portola' for the garden on Portola Road where one of our plants was planted and from which all subsequent cuttings were taken. This selection produces its leaves on shorter internodes and makes a fuller looking and much more attractive plant then the typical form of the 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 on this page is based on research conducted about this plant in our library and from reliable online sources. We also take into consideration observations of this plant in our nursery crops, as well as of plants growing in the nursery's garden and those in other gardens we visit. We also will incorporate comments that we receive from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing Polygala virgata 'Portola'.
