How to Choose and Grow Perennial Vegetables in Your Garden

How to Choose and Grow Perennial Vegetables in your Garden Header

Besides several perennial vegetables known worldwide, such as artichoke, rhubarb, and asparagus, this group of edible plants is fairly unknown to gardeners. Fortunately, perennial veggies are becoming more popular and widely available. Anyone who’d like to have an abundant, unusual garden full of different flavors should definitely try growing perennial vegetables.


The plants that are cultivated for their edible parts, and have a lifespan of more than three years, are considered perennial vegetables. Those edible parts can be leaves, tubers, bulbs, beans, shoots, flowers, leaf stems, etc. Some gardeners include herbs in this group, especially if an herb can be used in bulk amounts to make a dish.

Some of these plants have a short lifespan, some of them will live for decades. However, they all can be harvested year after year, without killing the plant. Many of them will reward you with crop during the trickiest period of the year when the annuals are just being sowed and there’s nothing to harvest.

In comparison with annuals, perennial vegetables are planted once and require less care and work. They are often highly nutritious and have a stronger flavor than their annual counterpart.


The plants that fall within this group belong to various families and are native to different regions. Since they’re so diverse, there’s no general tip for growing perennial vegetables. But, one thing is sure – they are fairly low-maintenance plants.

One of the best things about perennial vegetables is that you can find a dozen of plants for your garden, no matter the climate. Arid, temperate, subpolar climates, subtropical, desert…there are perfect perennial edibles for any climate. Many perennial vegetables can survive a harsh winter even in temperate and cool regions.

But before you start planning your edible perennial garden, consider the conditions of your garden. The soil type, its drainage and acidity, sun exposure, available space, and of course – your overall climate, will determine what plants you will grow.

Don’t forget to check whether a plant you’re interested in is listed as an invasive species in your region. In that case, a species may be prohibited by law. And what’s more, an invasive plant can cause various problems to your garden ecosystem and give you a headache in an attempt to get rid of it.

As extra, perennial vegetables are particularly convenient for landscaping. Their various sizes, colors, growth forms, and other decorative and ornamental features can give a lot of interest to your garden. There are even some aquatic species that can be grown in a pond garden.
