It’s hard to find out a garden without perennials. Gardeners like them for unpretentiousness. Perennials please us with an abundant flowering every spring! Unlike annuals, perennials can grow in a garden for many years. The most popular and decorative perennial long-livers are hosta and astilbe. They grow at the same place for 15 years! Peonies grow longer, if you take care after them properly the flowering will be abundant for 20-30 years!
