Description: These yams have been being grown ‘forever’ by Denise’s grandmother in the Thames area, so they are very special for those of us in the north, because yams normally require colder winters. These yams grow very big tops and have yellow flowers. Make sure you do not harvest them until the tops have totally died back or you will not get a crop!

Planting Instructions: Prefer a deep, free draining soil and are easier to grow in colder areas. Plant in the Spring at 40cm centres 5cm deep in trenches and hill up as tops grow. Do not harvest until the tops have totally died back as the tubers will not be formed. Watch the birds, they love digging them up.
