Broccoli Amadeus F1
The Broccoli that Steve Solomon regards as one of the best. I just had to bring this seed in from America based on his recommendation. Broccoli Amadeus is an early that produces a large main flower but also produces very large side shoots that can go on for months.
Amadeus side shoots are larger than many open pollinated varieties main head. An outstanding Broccoli especially for large families such as mine. Does well over the warmer months in Tasmania also.
Sow: September to March (early sowings indoors or protected outside as cold spells/frost can force seedlings into flowering)
Spacing: 40 to 50cm, 60cm rows (more if you water less).
- Broccoli resulted from breeding of landrace Brassica crops in the northern Mediterranean starting in about the sixth century BCE.
- Broccoli has its origins in primitive cultivars grown in the Roman Empire and was most likely improved via artificial selection in the southern Italian Peninsula or in Sicily.
- Broccoli was spread to northern Europe by the 18th century and brought to North America in the 19th century by Italian immigrants.
- After the Second World War, breeding of United States and Japanese F1 hybrids increased yields, quality, growth speed, and regional adaptation, which produced the cultivars that have been the most popular since then.
- There are three commonly grown types of broccoli. The most familiar is Calabrese broccoli, often referred to simply as “broccoli”, named after Calabria in Italy. It has large (10 to 20 cm) green heads and thick stalks. It is a cool-season annual crop.
- Sprouting broccoli (white or purple) has a larger number of heads with many thin stalks.
- Purple cauliflower or Violet Cauliflower is a type of broccoli grown in Europe and North America. It has a head shaped like cauliflower, but consisting of many tiny flower buds. It sometimes, but not always, has a purple cast to the tips of the flower buds. Purple cauliflower may also be white, red, green, or other colours.
- The majority of broccoli cultivars are cool-weather crops that do poorly in hot summer weather. Broccoli grows best when exposed to an average daily temperature between 18 and 23 °C.
Germination: Optimal Soil temperature is 18 to 24 C (around 5-10 days to germination)
