Product Description

Grow a garden filled with the strange, yet unique, Romanesco Broccoli, from freshly harvested Brassica oleracea seeds. Romanesco is an Italian heirloom and has been enjoyed for years, since the 16th century. The heads display apple-green, whorled pinnacles on 7 inch heads. The plants themselves can easily spread 3 feet wide, and grow to a mature height of about 2 or 3 feet tall. Romanesco boasts a mild, yet nutty flavoring and is often eaten raw, or cooked.

Romanesco Broccoli is categorized as an annual crop. Annuals such as this will grow quickly from freshly harvested seeds, producing flowers, fruits and seeds all within a single season. Romanesco is just one variety of Broccoli that we have to offer. check out our Broccoli seed category for additional varieties. You may also be interested in our Purple Cauliflower variety as well.

Sowing The Seed

Romanesco Broccoli is a cool weather crop that can be started indoors, or directly outdoors. If started indoors, sow in starter pots, 4 to 6 weeks prior to the last frost. If started outdoors in the Spring, sow just before the last frost, or in mid-summer, for a fall harvest. Till your sowing area, removing all unwanted plant life and weeds. Sow the seeds at a depth of 1/4” under, in rows measured about 10’ long.

Growing Conditions

Broccoli will grow in an area that receives full sunlight for at least 6 hours daily. The plants will bolt and go to seed if temperatures are too high. the soil should be fertile and rich in organic matter, but also well drained. To improve drainage, we recommend adding a light compost to areas containing hard, compact soil. Water daily to ensure that the seeds receive enough moisture to germinate properly.

Germination & Growth

Broccoli seeds typically germinate within 7 to 14 days after sowing. The plants will grow 2 to 3 feet tall, spreading about 12 inches wide. They can be spaced 18 to 24 inches apart from one another, in rows spaced 24 inches apart. Romanesco will produce 5 to 6 inch, spiraled, lime green heads that boast a better flavoring than most finer Broccoli’s available. They are ready for harvesting in roughly 75 to 100 days.

Harvesting Romanesco Broccoli

Grande Rio Verde will be ready for harvesting in roughly 80 to 85 days. The fruits will develop a papery husk, and the fruits will willingly drop to the ground when they are ready to be consumed. Grande Rio Verde fruits can be stored in the fridge, in ziplock bags for a good two weeks, and can also be frozen as well.

Question: What is the difference between a hybrid variety and a GMO based seed product.
Answer: Hybrids are a NATURAL process of cross pollinating two species, thus producing a first generation hybrid (F1.) For example: Mixing a red, double blooming, single stem sunflower, with a yellow, multi branching sunflower might result in a orange-red, double blooming, multibranching plant.

GMO based seed products are a completely different and unatural process of gene splicing in a laboratory. The process entails the introduction of a separate biological kingdom, such as a bacteria, or a pesticide. This bacteria or pesticide is then eaten directly by the consumer when the crops reach maturity. (BAD NEWS)

Question: Can you ship these seeds overseas?
Answer: At this time we only ship within the United States and Canada.
