Broccoli
Brassica oleracea var. italica/cymosaBroccoliis is as far as one knows, originally an Italian cabbage plant. It was greatly appreciated by the Romans, who called it the five fingers of Jupiter. Despite the Romans spreading it over large parts of Europe it was not grown to any great extent until the 1500s. It was then bi-annual, not producing flower heads until the second year. The broccoli was not just green then but also violet, brown, red and creamy. Most of these brightly coloured varieties disappeared as late as in the 1800s. There are however some left. Broccoli is easy to grow and is not as demanding as for instance cauliflower, which is its closest relative, but a good supply of water is important. It is very nutritious and is grown and appreciated more and more. Read the chapter on growing cabbage plants for more advice on cultivation.
The differences between the hybrids and the normally pollinated sorts are very evident. The hybrids, generally, have larger, denser and heavier central heads while the standard sorts often yield several and larger side-shoots. The advantage in the total crop is therefore sometimes with the standard sorts. All the hybrids are ready for harvest at the same time, for good and bad, while the standard sorts can be harvested for a longer time. The uniformity of the hybrids does not exist in the normally pollinated sorts, their heads vary in size. Where taste is concerned the standard sorts are superior usually. The few normally pollinated sorts remaining today lead a languishing life, perpetually in the shadow of the broccoli-hybrids.
SOWING: Sow thinly indoors or in a hotbed, about 1cm deep, 4-6 weeks before setting out the plants as planned! The seeds want warmth when germinating, preferably just above 20C. After sprouting they should be in a light, cool and airy place to avoid lankiness and attacks by root-neck rot but not lower than 14C for any length of time. Low temperature increases the risk of bolters a lot. Temper the plants gradually before setting them, when the risk of frost is just about over. Most kinds of cabbage can handle a night of light frost. Set out the seedlings a little deeper and tread down the soil preventing the cabbage flies laying their eggs. Many early sorts can be sown directly as soon as the soil has warmed up. Do not allow the sowing to dry out and look out for the flea-beetles.
SEEDS: 200-300/g, one portion yields 50-100 seedlings after pre-cultivation and sows 5-10 m directly. 8-10 g for 100 seedlings and a little less than 10 g sow 100 m.
