Gardeners' Notes:

The sepals of this type are those of Ipomoea nil and the entry should ideally be listed that way.

The fact that this Ipomoea nil will not cross with I.purpurea or Ipomoea hederacea,but will cross with other Ipomoea nil,is realistically a clear indication of the species identity.
