I am thinking about growing some Eryngium, like Blue sea holly. I have a south facing garden and would like to place them in a border. Has anyone else grown these and what were your experinces of the height and width?
I was inspired by seeing them in a florist and they really do look fantastic.
Sounds like you have a good spot. I have some in my garden. They easily get over 1-1.5 metres. Add grit to the planting hole and place at the back of the border. Apart from good sun and drainage and cutting them down nowish then they are easy.
As Blairs says but there are some dwarf ones, I think called Blue Hobbit which only grow to about 6 inches.
