Hi George,
I did take a few shots about three years ago but don't have them any longer. I've been hoping to get out there again since it's a year or more since my last visit. unfortunately they don't open at weekends now - just on weekdays. I'm currently waiting for a dry day too! June is the best month of all to visit there perhaps since they have so many roses (some great rose-covered tunnels) but there's plenty of other stuff to see as well so it's worth a visit any time for those of us who live within reasonable travelling distance. You'll have no doubt since you've seen the catalogue that their prices are extremely good too. If I get any shots from there I'll send them on.
Regards,
Trevor
