I have found an unopened packet of sunflower seeds with an expiry date of 2013. Will they germinate?
Can anyone recommend flowers/shrubs that are not affected by male dog urine?
They may but the best way to find out is to soak them for half an hour place in damp kitchen roll and seal in a clear box somewhere warm. They should germinate in 14 days.
Have you considered plants in pots to keep them away from the dog
A raised bed would be fine but I want to put some plants around a drain cover on the lawn. There's a rhododendron in a tall stone pot in the centre and I want something compact to go around the circumference of the circle. The boxus has died and now the yew has died.

Regarding the seeds; you can but try. Individual ones will become unviable in it's own time, so don't assume all will germinate, but you won't know until you try.
