The Immunity Garden

In 2021, the importance of wellbeing and a healthy immune system will be more top of mind than ever.  And the more colors on your plate, the better off you'll be.

Planting a garden full of vibrant vegetables fosters a diverse diet loaded with antioxidants and nutrients that support your immune system (1), while a dazzling medley of squash, radishes and tomatoes adds appetizing eye candy to your garden and your salad bowl.

The colors of your vegetables reflect the different phytonutrients and antioxidants inside (2). That's why multi-hued meals give you more health benefits and disease-fighting power than monochromatic ones.  Try growing the following nutrient-rich vegetables - selected by Burpee GardenCast experts - to color your 2021 diet.


Grow the Rainbow


COLOR CATEGORY

RED Tomatoes

NUTRIENTS & BENEFITS

Tomatoes get their ruby red hue from lycopene, a powerful antioxidant that promotes heart health by helping to improve cholesterol levels (3).  Lycopene may also reduce risk for prostate (4) and breast cancers (5).

BURPEE TIP

Stretch out your tomato season by planting one or more varieties at different times - early, middle or late summer.

ORANGE Squash

The sweet orange flesh of winter squash is rich in vitamin C, which aids immune function (6).  By enhancing iron absorption, Vitamin C also helps energize the body and fight fatigue (7).

Squash plants have a shallow root system, so use mulches to help retain soil moisture and maintain even soil temperatures.

YELLOW Pepper

Crispy yellow peppers are packed with vitamins, including brain-boosters B6 and B9 (also known as folate).  B vitamins support memory function (8) and may help ward off depression (9).

Pepper plants require steady watering, but they won't tolerate waterlogged roots.  Add organic matter to soil when planting to regulate soil moisture.

GREEN Broccoli

Tree-like broccoli is full of fiber, which is critical for good digestive health and bowel function.  Its fiber and antioxidants also aid in controlling blood sugar levels (10).

Pick broccoli when the heads have tight, firm buds.  This happens about 50-60 days after transplant.

GREEN Swiss Chard

Leafy and tender green chard is a ripe source of essential minerals - especially magnesium, a critical supporter of muscle and nerve function (11).

Chard plants that are harvested regularly will continue to produce new growth from the center of the plant.

PURPLE Radishes

Anthocyanins give radishes their elegant colors, and they also have cancer-fighting properties.  The natural pigments have been shown to prevent and curb cancer cell growth (12).

Sow radishes in midsummer for late fall and winter use.  They can grow large with several inches of root showing above ground.


EXPERT TIP

"Planting an Immunity Garden right in your own backyard will do a world of good.  It offers unlimited access to nutrient-dense vegetables that help support your overall health and wellbeing.  Tomatoes are a great example - they are rich in vitamin C, which plays a vital role in a healthy immune system." - Marisa Moore, Registered Dietitian
