Hi chuck,
It's a stake, it can be pushed into the ground so nothing to attach, I do like the heather idea very much and will investigate that further, maybe in the spring.
I rang the home manager this morning to check that our plans for Saturday would be okay and she was very helpful and readily agreed. I think mum's right, there should be something to mark the spot where we scatter her ashes, a memorial for the future.
Cheers
Leigh
