We use loads of these in the garden, best put on early before a plant starts to flop they add a wonderful structure to borders. All made to last from 8mm round metal.
Available online in 2 sizes:
30cm x 50cm tall - £25.00
40cm x 75cm tall - £27.50
Larger sizes are available at the gardens but sadly due to difficulties in posting not online. Prices are also slightly more expensive online to help cover postage and packaging costs.
