I do like to see a nice garden but to be honest I don't know that much about plants and shrubs and have made many mistakes over the years and this year is no exception
I had some nice Campanula in my front border, a lovely lavender blue colour and a cream coloured variety. When they are growing and before they flower they just look like long grasses and that is what I thought they were when I pulled them out! Not wanting to make the same mistake in the middle border I let the "grasses" grow and they turned ou to be grasses so I pulled them out too
Hopefully I'll learn by my mistakes in the future
