I have a bed including an arc of ten Gaura linderheimeri (pink). I planted them as young plants from a nursery last spring, they flowered well last summer, I cut them back by 90-95% on 5jan14 (when they were showing signs of sprouting from the base), and they have bushed-up nicely now - promising another excellent show of flowers this summer.
...All except one, in the middle of the arc, which has some shoots mottled yellow and stunted relative to some adjacent shoots which are as good as on adjacent plants. All the plants in as much of an identical setting as you could imagine practically - bare soil on one side, Carpobrotus on the other (kept at bay by pruning), soil ~identical, exposure ~identical, etc. No signs of cat/dog peeing.
So - is this virus? and what does the team think - have it out?, prune-out infected parts?, treat with something?
Your thoughts appreciated..
Mike
