“Odd” plants have reddish tinge on leaves and leaves are larger, thinner, and a bit wrinkled.

In this one, you can see normal DSV in the centre of the photo and at the right.

This is for location. The green stuff is the shade cloth on the west side of our plant nursery (between the two sheds). If you walk straight along here, duck under the large hawthorn tree at the back of the photo, you’ll see the patch of odd DSV just below that tree.
