Where To Buy Purple Broccoli
Purple foods like PSB can be nutritious additions to human diets. The purple color of PSB sprouts is due to an antioxidant compound known as anthocyanin that both serves to protect the plant and offers numerous health benefits to eaters. Scientific studies have shown that anthocyanins have the ability to help protect against cancer, obesity, and diabetes as well as having antioxidative and antimicrobial properties. They also improve visual and neurological health and protect us against various non-communicable diseases (Hock et al, 2017).

Purple sprouting broccoli can be confused with Broccolini which is a hybrid cross of broccoli and gai lan (also known as Chinese broccoli) due to similar appearance and harvest times. Both crops produce at the same time of year and are often sold in floret bunches side by side on produce shelves. However, spring Broccolini is usually grown in California or Arizona, whereas PSB is largely grown in the PNW.
Several farmers on the Olympic Peninsula in Washington State reported that PSB production in the late winter and early spring brings a lot of value to their farm operations. The harvest window fills a gap when few other crops are available to be harvested and the greens and sprouts sell well at winter and year-round farmers markets. Crops that can be sold in the off season are high in value and sought after by farmers in the region where (some) year-round production is possible. One farm collaborator shared that the revenue they make at the winter/off-season markets often ends up determining if they will have a net profit from the season or break even.
This guide provides production and marketing information, and inspiration for growing purple sprouting broccoli greens, sprouts, and seeds in the PNW and comparable climates. Included are general cultivation and marketing tips to support successful production and sales of PSB for growers new to the crop or considering increasing production and expanding sales.
Growing PSB through the winter is a balancing act for PNW growers. The crop requires a period of cold accumulation known as vernalization to transition from the vegetative, leafy growth stage to the reproductive stage when sprouts form. Growing slowly throughout the winter allows PSB plants to accumulate the cold needed to trigger this transition and provide a bounty of beautiful purple sprouts in the early spring.
Purple sprouting broccoli plants can get quite large and like to be given a fair bit of space to grow. They thrive in well fertilized ground. The recommended planting density is 18 inches in row and 24 to 36 inches between rows.
There are several strategies for managing and maximizing PSB sprout production. The central sprout is the first production on most varieties, and can be quite large and more similar to a heading broccoli than a sprouting one. Some growers snap and discard this head when it is still small and immature to direct energy for lateral sprout growth. Others allow the central head to develop and either sell it loose by the pound, bundle three or four together (the stems are much thicker and shorter on the central head than the lateral sprouts) and sell them as a bunch, or harvest them for crew eating until there is robust enough production that they can be incorporated into bunches alongside lateral stems. All of these approaches have proven successful, taking into account the timing, market opportunities and demand, and crew and field needs of each farm.
Purple sprouting broccoli is an outcrossing, insect pollinated seed crop. Each plant needs to share and exchange pollen with other plants in order to maintain the health and viability of the variety. It is recommended to grow and save seed from a population of at least 50 plants for high-quality seed. A population is a community of individual plants within a species that can intermate and shares a common gene pool. For more information on population size please see the OSA publication Introduction to On-Farm Organic Plant Breeding.
Being a Brassica oleracea crop, PSB is cross compatible with any other Brassica oleracea crop such as kale, broccoli, cabbage, collards, and cauliflower. This means that cross-pollination is possible between PSB and any of these other crops. Taking care to ensure there are no other flowering Brassica oleracea crops within close range (up to a mile depending on terrain and natural and structural barriers) is essential to maintaining integrity and variety purity of a PSB seed crop. This can be especially challenging with PSB as it starts to flower right around the same time as raab from other oleracea crops.
In fields where wind is a problem, staking can be necessary once plants achieve full seed production maturity size. Even without consistently windy conditions, staking may be necessary since the plants can topple under the weight of a heavy top of flowering shoots and developing siliques.
Purple sprouting broccoli will flower over an extended period of time and so seeds will also mature over an extended period of time rather than all at once. There are two indicators for knowing when the seed is ready to harvest. First, when the siliques have turned light tan or buff colored and begin to feel dry or leathery to the touch. Second, when the seeds inside have turned from green to brown/black/purple.
Exploring various cool season crop options is a great way toextend your growing season. Many vegetables are actually enhanced by exposureto frost or cold temperatures. In fact, you may be surprised to learn the coldtolerance of some vegetables yields promising overwintering potential. PurpleSprouting broccoli, also known as winter sprouting broccoli, is one example.
Purple broccoli plants are extremely cold hardy withstanding temps below 10 degrees F. (-12 C.). This unique attribute is critical to success in growing the plant, as Purple Sprouting broccoli growing will require at least 180 days to mature.
Unlike other broccoliplants, which produce a single large head, Purple Sprouting broccoli plantsproduce smaller heads with multitudes of tender side shoots. These shoots oftentaste especially sweet and delectable due to their exposure to coolertemperatures.
First, gardeners will need to determine the best time forplanting. With Purple Sprouting broccoli, care should be taken to ensure thatthe plants are grown throughout the coolest portion of the growing season.
Beyond transplant, Purple Sprouting broccoli care willrequire some attention to detail. Proper irrigation and fertilization will beimperative to success. These heavy feeding plants need a well-amended location thatreceives full sun.
Purple broccoli is a strain of Sprouting broccoli that was developed by Dr. Gray of Wellesbourne, England. It requires an unusually lengthy growing season, with planting in late spring, overwintering for the rest of the year and harvesting in early Spring the following year. The long length of time and multiple seasons it takes to bring crops to harvest can be cost, space and time prohibitive. Thus, Purple broccoli is an uncommon commercial variety limited in exposure primarily to Italy, United Kingdom and Southern California. Market expansion for Purple Sprouting broccoli varieties is almost certain as breeders recently developed a hybrid called Bordeaux that does not require overwintering.
Purple Broccoli is a sprouting type, and also a member of the Brassicaceae family. The vegetable is available in the late winter and early spring months. Purple broccoli is more versatile than the regular broccoli because it is more tender and cooks more quickly on high heat. However, the plant loses its purple color because of the high heat. Purple Broccoli provides a nutty and peppery flavor, with a bit of bitterness which is common for vegetables from the Brassica family.
When looking to buy the perfect broccoli, look for tight florets and firm stalks. The vegetable itself should feel a bit heavier for its size. The end of the stalks should be moist and fresh. Avoid broccoli that has dried our browning stems.
A classic favorite in the garden. Mostly used for sprouting, but once full maturity is reached dark purple heads will form. Eaten fresh these will retain their purple hue, however once cooked they will turn green again. Worth growing in any garden!
Anthocyanins comprise the largest subclass of hydrosoluble pigments conferring red, orange, purple, and blue colorations to flowers, fruits, seeds, and vegetables in plants (Cominelli et al., 2008; Espley et al., 2007; Li et al., 2017). Anthocyanins play important roles in furnishing flowers and fruits for attracting pollinations and dispersers, protecting plants from various biotic and abiotic stressors (Harborne & Williams, 2000; Ahmed et al., 2014). In addition, the health benefits of anthocyanins attract growing attention due to their antioxidant activities (Pojer et al., 2013). Genetic parameters, developmental stages and environmental conditions control anthocyanin accumulation, including high-light, UV-light, cold temperature, nutrient availability and infection (Dixon & Paiva, 1995; Chalker-Scott, 1999). Based on the above, a comprehensive understanding of regulation of anthocyanin biosynthesis should be investigated to obtain anthocyanin-rich foods via breeding and/or environmental control.
