Many thanks for the list but with respect I asked for a recomendation. I have bought plants on line before and was disapointed on a number of ocastions which is why I ask for recomendations.
That was not clear from you question.
"Could someone offer a suggestion as to a respecible Garden Centre that is worth using?"
No good giving you the name of a fab nursery if they do not sell the honey suckle you want. Those 20 nurseries listed all say they sell it.
Personally I hate mail order...I would far rather be able to chose my plant myself.
However as we are all on lockdown just now if you want one now you will have to do mail order.
I can recommend Crug farm, Cotswold, Larch cottage, Ashwood, Place for plants....from that list.
The others may also be brilliant.
But as I have never used them I cannot comment.
