While you may have heard of perennials and annuals, did you know that there are also biennials? These wonderful plants have a two-year cycle.  The first year they develop root systems, grow out their leaves, and start storing nutrients. The second year they flower, produce and disperse seeds, and then “die”. While this may seem odd, there are a ton of benefits to having biennials in your garden. These plants are much more tolerable to colder weather, they have long bloom periods, most are self-sowing, and they are relatively low-maintenance. And with a little careful planning you can have your favorite biennials growing in your garden every year. That’s why today we will share with you some of our favorite biennial plants that would make a wonderful addition to any garden.

Best Biennial Plants

Biennials are a great addition to the garden. They bloom for long periods, they self-seed, so you don’t have to constantly replant them, and they are drought and cold tolerant. And if you want biennials every year, you just have to plant one batch one year, and then the next batch next year. This way you can enjoy them every year! However, do keep in mind that some biennials can behave differently depending on what climate you are in. In warmer regions, they may act more like annuals, while in colder climates it may take them longer than two years to produce blooms. But you can easily pick your biennials based on your growing conditions. Here are some of our favorites for inspiration.
