Invasive plants can take over your landscape, causing the gardener to invest extra effort to control what seemed to be a low-maintenance plant. The invasive plant can spread to neighboring properties, becoming a nuisance in other gardens. Finally, even if you think your invasive plant is under control, birds could be spreading seeds to sensitive areas susceptible to aggressive species. Learn about flowers that don’t mind their manners, and discover easy hybrids and wildflower replacements. If you’re looking for a hardy, low-maintenance rose, plant a rose from the ‘Knock Out,’ ‘Drift,’ or ‘Carefree’ series. These will bloom all season with little more than annual pruning. Instead of Chinese wisteria, choose the native and equally lovely Wisteria frutescens. It has a less aggressive growth habit, with a mature height more suitable to gardens than its massive Asian counterpart.
