This heirloom Walcheren overwintering cauliflower was developed in England. Galleon cauliflower seeds produce very reliable results. Expect to harvest at the end of April and in early May. Heads are 10-15cm (4-6") in diameter on a big plant and will withstand frost from -12 to -19°C (16 to -5°F) depending on wind and snow cover. Galleon doesn't start curd formation until after the winter frosts. Timing is critical. The object is to grow a plant about 15cm (6") tall by first fall frost. Try mid-July if starting indoors and transplant in mid-August. If seeding outdoors in a nursery bed, plant a little earlier. Transplant into well-drained soil in a spot protected from wind. Space plants at 60 x 75cm (24 x 30"). In spring when they start to leaf out, sprinkle nitrogen fertilizer around the base of each plant. Winner of the RHS Award of Garden Merit.
