Roman broccoli Cornelio seeds

As mentioned, Cornelio broccoli stands out for its unmistakable pyramidal shape and for seeds of very high quality, ensuring regular and even germination. Roman broccoli, also called romanesco, is the typical Lazio variety of the large Brassica oleracea family, the same one as cabbage and savoy cabbage. What is eaten from this plant is its characteristic fractal-shaped inflorescence, harvested while still slightly immature, one of the most striking and recognizable vegetables in the Italian garden.

The Roman broccoli Cornelio plant

Its botanical name is Brassica oleracea var. italica, belonging to the Cruciferae family (Brassicaceae). As mentioned, the Cornelio variety stands out above all for its earliness: it is indeed one of the fastest among Roman broccoli varieties, adapting well to any type of soil and tolerating even lower temperatures without issue.

The plant has large, bright green leaves at its base, which protect and support the development of the central inflorescence, which retains the classic spiral pyramidal shape typical of romanesco.

How to sow Roman broccoli Cornelio

Thanks to its earliness, Cornelio can be sown slightly later than other varieties, generally between July and August, burying the seeds about half a centimeter deep in soft, well-drained soil. Transplanting into open ground happens once the seedlings have developed 4-5 true leaves, keeping a spacing of about 50-60 centimeters between plants.

This variety adapts well to different soil types, although it prefers a fertile, organically rich, well-drained substrate. Watering should be regular, avoiding waterlogging. Thanks to its hardiness and good cold tolerance, Cornelio is particularly well suited to late-autumn or winter crops in colder climates.

Harvest should take place while the inflorescence is still compact and tightly closed, before the individual flower buds become visible. Thanks to this variety's fast development, the time between sowing and harvest is generally shorter than with other Roman broccoli cultivars.

Given its good tolerance to low temperatures, Cornelio is an ideal choice for those who want to extend the garden season into the colder months. It is still advisable to protect freshly transplanted seedlings with garden fleece during the first few weeks, to help them establish well.

Diseases and pests of Roman broccoli Cornelio

Like all Cruciferae, Cornelio can also be attacked by cabbage white caterpillars and cutworms, green larvae that can be controlled with Bacillus thuringiensis treatments. Whitefly and aphids are other common pests: natural garlic or nettle macerates, applied regularly to the foliage, are effective at keeping the latter away.

Properties of Roman broccoli Cornelio
