- Spinach
One of the best leafy greens for vertical gardens is spinach (Spinacia oleracea). This versatile vegetable thrives in many climates, and the climbing properties of its stalks make it an optimal choice for vertical gardening. Spinach is a great source of vitamins A, C, and K, as well as iron and calcium. It’s a nutrient-dense leafy green that can be incorporated into a multitude of dishes, from salads and smoothies to sauteed sides. Spinach plants also have a fast growth cycle, allowing for multiple rounds of harvest from the same plants. For successful vertical farming of spinach, expandable trellis systems are often the best choice, providing ample room for the plants’ spreading leaves.
- Swiss Chard
Swiss Chard (Beta vulgaris) is another fantastic leafy green for use in vertical gardening. Its vibrant stems, ranging in colors from yellow to pink to red, add a visual appeal to your garden while its large leaves can serve as a healthy dietary addition. The Swiss Chard is rich in antioxidants and vitamins like K and A. It’s tolerant of both heat and cold ranges, making it a reliable year-round option. Using perm culture methods for its cultivation can promote a more diverse, self-sustaining ecosystem, making this leafy green an excellent option for sustainability-focused gardeners.
- Lettuce
Vertical farming of leaf lettuce (Lactuca sativa) is another eco-friendly and space-efficient option. With hundreds of varieties to choose from, lettuce can provide a bounty of textures and flavors to your meals. It provides vitamins K, A, and C and is low-calorie content making it a staple in health-conscious diets. From the crunchy Iceberg to the tender Butterhead, to the colorful Romaine – there’s a type of lettuce to suit every palate. Lettuce thrives in cooler climates but can be grown year-round using the right vertical gardening techniques, such as hydroponic systems.
- Asian Greens
Underrated but highly beneficial, Asian Greens like bok choy (Brassica rapa subsp chinensis) and Mitsuba (Cryptotaenia japonica) can thrive in vertical gardens. High in Vitamin A, C, and calcium, these leafy greens are excellent nutritional additions to your diet. Bok choy’s compact growth habits make it perfect for vertical farming. It grows quickly, usually ready for harvest in just 6-7 weeks. On the other hand, the Japanese Mitsuba, also known as Japanese parsley, adds a unique, spicy flavor to cuisines. It thrives in the partial shade, making it suitable for indoor vertical farms or outdoor setups with limited sunlight.
- Kale
Kale (Brassica oleracea) has grown in popularity due to its high nutrient content and versatility in the kitchen. It’s an excellent source of Vitamin K, Vitamin A, and Vitamin C. Popular varieties like Curly Kale and Dinosaur Kale have proven to work well in vertical gardening systems. Since Kale has a longer growing cycle compared to some other leafy greens, using a vertical gardening system can allow you to make the most of your garden space while waiting for the Kale to reach its full potential.
- Arugula
Arugula (Eruca sativa) is a leafy green often used in salads or as a garnish, known for its peppery flavor. The comfort and ease of growing arugula make it an excellent choice for gardening beginners. This leafy green is highly resistant to pests, and its relatively short growth cycle allows for multiple harvests throughout the growing season. A vertical gardening setup can easily accommodate arugula, especially when taking advantage of techniques like staggered planting.
- Mustard Greens
Mustard Greens (Brassica juncea) are well-known for their spicy kick and rich nutrients, such as vitamins A, K, and C, and they add a punch to a wide variety of dishes. They have a quick growth cycle, often ready for harvest within a month of planting.
