I think this could easily fetch low to mid xxx.
For someone who is a gardener this would be a great little domain.
I've been teaching a few basic "get your business online" classes and it always amazes me to see how many small businesses are using really bad domain names. When I show them Netfleet etc. some are usually quite happy to pay for a better name. 2 people in my last class were gardeners.
Cheers,
