How to Care for the Plant

Water
Water abundantly in summer (never flood) and moderately the rest of the year (wait for the substrate to dry).
Pruning
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.
Fertilizer
Fertilize every 20 days with mineral fertilizer during the summer to promote flower production.
