Like many people, I've used Clockhouse Garden Centre on Forty Hill for many years. Just next door is the much less visited Glebe Nursery.
It's run by the brother and sister team of John and Gennie. They run the whole place by themselves and all plants are propagated and grown by them.
I've become a real fan. The prices are very competitive with most established plants being just £4.00. All the plants are very healthy. As to the range, you can download a stock list from their website.
If you go up to Crews or Forty Hill for your garden supplies, I recommend you checking this place out.
I’m also a big fan of Glebe Nursery and second Hugh’s recommendation, it’s a lovely place,
I knew I couldn't be the only one who'd 'discovered' this place!
Great nursery, and fantastic plants.
