Polygala vulgaris is a perential growing to 0.4 m (1ft 4in). It is hardy to zone (UK) 6. It is in flower from May to September. The species is hermaphrodite (has both male and female organs). It prefers moist soil.
Water abundantly in summer (never flood) and moderately the rest of the year (wait for the substrate to dry).
Grow in well-drained, moderately fertile soil in a sheltered, sunny site. Protect in winter in cold areas.
This variety has larger, more richly coloured flowers and more tapered, pointed leaves in comparison to the species. In habit, it’s a rounded, bushy shrub that can eventually become a small tree. Just a light prune of straggly stems after flowering is all that's needed to maintain a dense habit. Trimming after flowering will also encourage more flowers. Caterpillars like polygala, so use Dipel or Success Ultra to keep them away.
Temperatures between 65 (18 °C) to 75 F (23 °C) and nighttime temperatures between 50 t(10°C) to 60 F (15 °C).
