Wild Dagga

201 Very tall species. Stems erect and sparsely branched . Leaves are heart shaped and finely toothed. Whorls of orange flowers are widely spaced towards end of stems. The plants were covered in insects but mainly the Sunflower seed bug. L. dysophylla changes to L. intermedia when I press recommended and there is also a suggestion in my books that it is L. ocymifolia. So I really am a touch confused!
