Hi Lin,
I really have come to love Ferns since i first introduced them into the garden,..great space fillers as well,..oh that plant you admired,..i have two from cuttings i took almost 15 years ago,..they are Cytisus scoparious,..'Scotch Broom',..they come in a few different colors but mine are the most vivid,..they are about 8ft tall.
