You will get Kohlrabi German Turnip-Greens KOHL RABI Purple Vienna- 500mg seeds for Planting, fresh broccoli, Farm & Vegetable, Gardening & Micro Greens Seeds, Heirloom, Open Pollinated, Non-GMO
Kossak will reach a diameter of up to 8", and the interior will still be sweet, delicious and tender. Like most brassica or cole crops, kohl rabi grow best in cool weather. Little growth occurs above about 75F and they tend to become woody and fibrous.
Purplish leaves and globes with mild turnip-cabbage flavor. Leaves are eaten like kale and white-fleshed bulbs are eaten like broccoli. According to the USDA nutritional data, they are a good source of vitamin C and potassium and are low in both sodium and calories.
This close relative of the cabbage was bred over centuries to develop a flattened meristem. Sometimes referred to as German turnips. The flavour is like a very mild cabbage and the texture is crisp and crunchy, a bit like that of a pear.
Harvest the attractive purple kohlrabis at 6cm (2½") in diameter for the finest texture. Direct sow in early spring for a summer harvest, and again in August to harvest in the cool weather of the fall and winter. This is the most economical kohlrabi to use for microgreens, and their flavour is exceptional. USDA Zone: 3-9
Imagine slicing into a crisp, vibrant purple bulb for a summer salad that tastes more like a sweet pear than a heavy cabbage. These IB Prosperity Purple Vienna seeds are a game-changer for gardeners looking to maximize their cool-weather harvests. I found that planting them in early spring or again in August yields the most tender results before the heat makes them woody. You can actually eat almost the entire plant. The purplish leaves work beautifully as a kale substitute, while the white-fleshed bulbs offer a crunch similar to broccoli. Because they are non-GMO, open-pollinated heirloom seeds, they are incredibly reliable for both traditional garden beds and economical microgreen trays. Just keep an eye on the thermometer, as they thrive in the chill and struggle once temperatures climb above 75°F.

A Guide to Selecting the Best Summer Fresh Broccoli Seeds
Prioritize Heat Tolerance and Maturity Cycles
The most critical factor when buying broccoli seeds for summer production is the variety's ability to withstand thermal stress. Standard broccoli varieties often 'bolt'—meaning they prematurely send up a flower stalk—when temperatures exceed 80°F. This results in bitter, woody stems and tiny, unappealing heads. When browsing seed catalogs, look specifically for varieties labeled as 'heat tolerant' or those bred for longer growing seasons. Additionally, pay close attention to the days-to-maturity metric. In the summer, you want varieties that can reach maturity quickly to beat the peak heat of mid-summer, or varieties that thrive in the slightly declining temperatures of late summer.
Understand the Growing Habit: Determinate vs. Indeterminate
How the plant grows will dictate how much space you need and how you harvest. Some broccoli varieties are bred to produce one massive, central head, while others are more prolific, producing multiple smaller heads over a longer period. For summer gardening, where pests and heat can be unpredictable, choosing a variety that produces multiple heads can be a safer bet. If one head is damaged by heat or a pest, the plant may still yield others. Consider your garden layout: if you are using raised beds or containers, compact, bushy varieties are often more efficient than sprawling, large-leafed cultivars.
Disease Resistance is Non-Negotiable
Summer humidity often brings a host of fungal and bacterial issues that can wipe out a broccoli crop overnight. When selecting seeds, look for descriptions that mention resistance to common summer ailments such as downy mildew, black rot, or clubroot. A seed with a strong genetic foundation for disease resistance acts as your first line of defense, reducing the need for organic fungicides and ensuring a much higher success rate for the home gardener. High-quality seed companies will explicitly state which pathogens their varieties are bred to resist.
Flavor Profiles and Culinary Uses
Not all broccoli is created equal in the kitchen. Some varieties are bred for high sugar content, resulting in a sweeter, more tender head that is perfect for raw snacking or light steaming. Others are bred for density and structural integrity, making them better suited for roasting or stir-frying without falling apart. If you are growing for a family with picky eaters, lean toward sweeter, milder varieties. If you are an experienced cook looking for complex textures, you might opt for heirloom varieties that offer more robust, earthy flavors.
Seed Quality and Germination Rates
Finally, always check the germination percentage listed on the seed packaging. Summer gardening is a race against time and weather. You cannot afford to waste precious weeks waiting for seeds that refuse to sprout. Look for reputable seed producers that offer fresh, high-germination batches. High-quality seeds should be plump, free of debris, and stored in a cool, dry environment to ensure they retain their vigor until they hit your soil.

Quick answers about Summer Fresh Broccoli before you buy.
Summer-friendly varieties are typically heat-tolerant and have a shorter maturity window, allowing them to reach harvest before the peak summer heat causes the plant to bolt or flower prematurely.
Choose heat-tolerant cultivars specifically bred for warmer climates and utilize mulch or shade cloths to keep the soil temperature cool and consistent.
For a summer harvest, aim to plant in early spring so the plants establish themselves before the intense heat, or look for quick-maturing varieties that can handle mid-season planting.
While the flavor profile is similar, summer-grown broccoli can sometimes have a slightly more tender stem, provided they are harvested at the peak of head development before heat stress sets in.
Broccoli generally prefers full sun, but in extreme summer heat, providing afternoon shade can prevent the heads from becoming bitter or woody.
Yes, container gardening is an excellent way to control soil temperature and moisture, which is critical for preventing heat stress in summer broccoli varieties.
Consistent moisture is vital. Summer broccoli requires regular watering to prevent the soil from drying out, which can trigger rapid bolting and bitter tasting heads.
Harvest your broccoli when the heads are tight and compact. If you see any yellow flower buds starting to open, harvest immediately to avoid a woody texture.
