The area was marred by the numerous holes left by the miners. The of about 1.8km redoubtable Baron von Mueller provided much of the material for the earlier plantings, some of which still exist. The National Trust has placed a number of trees on the State Register of Significant Trees while an additional 7 are regarded as significant although not registered . In the gardens there are 8 different species of pine as well as the State Buddleia collection. In 1984-5 the Melbourne Botanic Gardens Rejuvenation Subcommittee identified most of the trees and some shrubs by numbers on small metal tags attached on the north side of the trunk. Many of these tags have now disappeared, but significant trees have been provided with clear labels. In these notes, the tag numbers are preceded by #. The Gardens have recently undergone a $2.5 million refurbishment which included an upgrade of the children’s playground and the picnic area. Electric barbecues and picnic tables under shelter now make this a popular venue.
