8. Topsetting, walking or tree onion sets, The Real Seed Catalogue, One topsetting onion (4 bulbils in a packet to be sure of at least one success), £2.83, www.realseeds.co.uk.
A botanical oddity - topsetting onions are a class of bunching onions that instead of flowering, make a bunch of bulbils on the end of a flower stalk. They are also known as tree onions or walking onions because the flower stalk falls over, and the bulbils root where they touch the ground. The reproductive bulbils are small - about the size of a pea. To be sure of getting one to grow, four bulbils are sent out.
