Blue Jubilee Gem' is a double-flowered variety of blue knapweed. Less old (and less rare) than our 'Emperor WilliamHowever, it was already popular in 1937, when it won the silver medal at the All-American Selections. A good choice for bouquets, knapweed flowers are also edible and medicinal. They are especially useful in cases of eye inflammation and irritation, as well as for decongesting bronchial tubes and soothing coughs. An easy-to-grow annual that tolerates drought once established, and can be reseeded. 60 cm high.

Sow on site in spring, as soon as the soil can be worked. Leave 5 cm between seeds, then thin to 15 cm for optimum development. Germination will take 7 to 12 days, between 15°C and 18°C. This knapweed likes cool nights, so don't worry!

We also have the knapweed and the centaury Emperor William
