Hi group,
I have two Romneya coulteri ( Californian Poppy tree) side by side in the
garden, both came from the same nursery and were planted at the same time
eighteen months ago. Last year they flowered and looked great.
This year one is fine and the other is drooping and the leafage is going
yellow, in fact it looks as though the plant is dying slowly.

Please has anyone any idea what might be happening? Could it be a disease? I
would hate to lose both plants if it was.

Any help would be much appreciated.

Thanks in advance to all those that take the time to reply.

David.
