A new line bred Den. speciosum var. speciosum with white flowers.
Variety speciosum is the southern form of this widely distributed species - it occurs naturally from just north of Newcastle, down to just over the NSW/Victoria border.
The parents I've used are 'Alick', a fairly large flowered white, and 'Kingfisher's Two Windy' a smaller flowered white with a high flower count. 'Kingfisher's Two Windy' is ('Two Up' x 'Windermere').
1st photo shows the two parents of the cross - 2nd and 3rd show the plants for sale. They're established in 80mm pots.
