One of the beauty's of the half hardy perennial Dioscorea is its cinnamon fragranced flowers.

These bloom anytime from spring to autumn (variety specific) with small white flowers.

Cinnamon vine can be grown from either tubers or seeds. the seeds should be planted at a depth of 3mm at the end of September or on October, whereas tubers should be buried at a depth of 8cm following the last frost of spring. Dioscorea can be grown in either a partially shaded or sunny area of the garden that has good drainage and a deep soil.

As Dioscorea are climbers they should be provided a trellis to grow upon. You can grow Cinnamon vine seedlings indoors first, they take about three to six weeks to germinate at 21 to 24 degrees Centigrade. They should be moved outdoors in the middle of spring. Once growing provide plenty of water. If you require more plants then cuttings can be took, or the plant can be divided in the autumn.
