This is a constantly expanding list of great gardens to visit in the UK. They are not currently grouped by county or special features, because I haven't yet visited enough to give a true picture of what's on offer nationwide.

But this list will grow and by clicking on the links within this directory of gardens that I have visited to date, you will get taken directly to the garden and find pictures and information about it:

It's worth noting that Britain has many gardens in bloom throughout the year, so you don't need to be here in summer to appreciate them. I have listed properties below that are particularly noteworthy during other seasons. As with gardens in the above directory, this list is growing, so please bear with me! I visit 30-40 new gardens every year, but not all of them make the grade, but for a taster, click here.
