Garlic

Allium sativum (softneck)
Perennial
Ht 60cm.
Member of the onion family, made up of bulblets when mature.
This is the Garlic Farm's Solent Wight variety, grown as it's particularly well suited to the UK climate.
As a rule of thumb it's planted on the shortest day and ready to harvest around the longest day - but can be left for longer and should multiply further if left.
