Polygala 'Alta Grande' (Large Butterfly Sweet Pea Shrub) - A shrub we expect to grow to 3 to 4 feet tall with a dense rounded habit. It is has gray-green round leaves very similar, but larger than Polygala fruticosa 'Petite Butterfly'and also has a very free flowering nature like it with the purple pea-like flowers, composed of two winged petals surrounding a whitish purple lacy crest that can be found on the plant nearly year-round. Plant in full sun or part shade with regular to little irrigation.
Hardy to 15-20 F. Polygala fruticosa is a coastal species that can even be found within the splash zone. This would make this a good candidate for beachside plantings. It also makes a good cut flower and lasts well in arrangements though the stem length on this cultivar is a bit short. We were first made aware of this plant by Doug Zylstra of West Covina Wholesale who had purchased the plant from Alta Nursery as Polygala grandiflora – to commemorate its source and indicate its larger size, we have come to call this distinctive plant Polygala 'Alta Mariposa'.
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. This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Polygala 'Alta Mariposa'.
