Perennial Vegetables to Plant in Your Vegetable Garden

Perennial flowers are just amazing. Plant them once and they will bloom again and again throughout the year. That is why many gardeners prefer perennial flowers in their garden. Did you know that just like flowers, there are perennial vegetables which have to be grown only once and you can enjoy the harvest all year long?

Firstly, let us know the difference between annuals and perennials. Annual plants grow only for a particular season or a year and die. Perennials, on the other hand, grow for 1-2 years or 5-6 years like shrubs and trees. We are more familiar with annuals as they are easily available in the market.
