It’s a walled garden most of the way around with good tree cover. We are currently looking at ideas from the office here in Sydney. The internet gives a good idea for some plants, http://www.efloras.org/browse.aspx?flora_id=2&page=1 found this great site. But we are looking for a few unique plants for this space. So a plant nursery list would be great, I hear there are some large nurseries that have developed with Dutch design and input.
