Visit to the Geelong Botanic Gardens in spring 2014

The Geelong Botanic Gardens

Brief history of the gardens

The gardens were first established in 1856 and are the fourth oldest botanic gardens in Australia. The first curator of the gardens was the English born botanist and gardener Daniel Bunce who developed and expanded the gardens in terms of both its physical size and in the amount of established plants which it contained. In 1859 published a catalogue of 2,235 plants which he established in the gardens which is impressive considering he was only appointed curator in 1857. He was also responsible for many of the now mature trees, some of which are national trust trees.

The second curator was John Raddenberry who was responsible for reducing the amount of Bunce's blue gums and replacing them with more traditional English trees. He was also build a huge fernery (18 metres high) which was neglected then demolished. Around this time the gardens shrunk in size but in 1959 they were expanded again and in the present day they are large in size but also packed with interesting plants.



Entrance plantings

Upon arriving at the gardens I was impressed by the entrance which was announced with the flower spikes of several Xanthorrhoea plants and the swollen trunks of Queensland bottle (boab) trees. Xanthorrhoea plants are really expensive (you are charged per cm of height) and these ones were huge. Once I had walked into the gardens themselves I encountered what is known as the 21st Century garden which had a large pond (or billabong), a landscaped sand area, natives and exotics, a cactus bed and to my delight a tree named Dracaena draco (dragon tree). I had seen a another similar tree online called Dracaena cinnabari on the internet and didn't realize we had this similar tree in Victoria.

The swollen bellys of these trees were a dead give-away that they were boab trees aka Queensland bottle trees.




The amazing branch structure of the dragon tree (botanical name Dracaena draco).

The cactus bed with the classic barrel cactus in abundance. 







Rose and tea gardens

The next part of the gardens was the rose garden which had all the different types of old roses on display. Unfortunately none were in flower that day because seeing them all in flower would have been a great way to see their differences and would have helped me in future identification of old roses. Following the rose area was a section called the tea garden which contained plants to make teas and herbal infusions such as fennel and calendula.





I'm guessing this may have been the original entrance but it is now surrounded by the 21st century garden. There are two 'bollard people' one of which you can see in the picture below. The other bollard represents Daniel Bunce.





One half of the rose garden which unfortunately was not in flower at the time.

Rock pillar of the forgotten garden

After the rose and tea beds there was a large fountain close to several large banana trees complete with fruit. This area also had a section called the forgotten garden which I'm pretty sure is where the old fernery used to be. A large rock pillar which was covered in sprawling creeping fig remains in place. This pillar used to be at the centre of the massive fernery.

National trust trees and the temperate garden

Beyond the forgotten garden I found several of the national trust trees such as huge Ginkgo biloba (maidenhair tree) and one of my personal favourites a Californian redwood tree. Near the Ginkgo was an extensive collection of pelargonium plants and a section called the temperate garden.

The next two pictures are of the Pelargonium collection.






Parallel beds with interesting plants

I ended the visit with a walk through several of the parallel garden beds. I'm not entirely sure but I think these may have been part of Bunce's original design. From there I walked back through the new fern area and as to end the visit I saw a bizarre looking tree that seemed to be directing all its growth to one side. I didn't have time to properly identify it but I think it may have been a monkey puzzle tree. If you are interested in plants and gardens please visit the Geelong botanic gardens if you are in the area. You will not regret it.



One of the parallel beds bordered by good old English box.




At first I thought the plant in the next two pictures was a Correa but it was called Justicia pauciflora.





 Aucuba japonica or variegated Japanese laurel.





Justicia brandegeana common name shrimp bush. I guess I can see why it got that name.




 A flower on a South African bottle brush bush.




A view of the fernery with soft tree ferns a plenty.



Maybe this tree was once shaded out on one side causing its growth to be directed to one side.

The Royal Botanic Gardens in Melbourne Australia are under attack!

I visited the Royal Botanic Gardens Melbourne a couple of days ago and saw, amongst other things, damage that has been inflicted on trees and cacti by vandals. Probably the saddest sight was the Separation Tree which is a heritage tree that existed before Europeans colonized Australia.

The Separation Tree is named so because it is where citizens gathered to celebrate state of Victoria separating from the state of New South Wales in 1850. It also holds cultural significance for people indigenous to the area. It is a river redgum and is over 400 years old. The tree was ring barked back in 2010 and had survived by a technique called 'bridge grafting' where redgum sapling bark is grafted across the damaged area, thereby bridging the ring barking allowing energy photosynthesized by the leaves in the canopy to reach the tree's roots. Without the bridge grafts energy cannot be sent to the trees roots and they die. The dead roots cannot send water and nutrients up to the canopy and the canopy then dies. Needless to say it angers me and others to see it attacked once more as even with the bridge grafts the tree was still struggling to stay alive.

The most recent attack was on the 21st of July and amazingly it followed another attack which was on the area in the gardens known as 'Guilfoyle's Volcano' on July the 5th. Guilfoyles volcano is an area planted out with succulents and cacti. When I visited it the damaged plants were nearly all replaced but it didn't look quite as grand as many of the plants were smaller than the originals. Below is a link to a news report showing some of the scale of the damage to the cacti and succulents. In that attack most of the large plants in the succulent garden were damaged.

The attacks have prompted calls for better security to be installed to protect the gardens. The gardens CEO however, has stated  ''In the end though, the gardens can not, and should not, be a high-security compound" and also ''We seem to have a problem with a small number of individuals who have no regard for the importance of these trees and the significance of the gardens". If more attacks occur I personally think that tighter security is necessary and should be used.





The Separation Tree as I saw it on my visit. The hessian covers sphagnum moss in an effort to assist healing. I'm guessing that the moss is only a temporary measure and that bridge grafting will again take place.





Another victim, this time a spotted gum.






Sign of the times.






Attempted ring barking. I wonder whether they were disturbed and ran or if they just got tired and stopped?






This is the succulent garden that surrounds a water reservoir called 'Guilfoyle's Volcano' (not a real volcano of course).






The succulent garden was looking leaner than usual but impressive nonetheless.








More evidence of vandalism.






 'Guilfoyles Volcano' was built in 1876 to store water for the gardens. For 60 years it was left idle but has now been restored. William Guilfoyle become the second director of the Royal Botanic Gardens in Melbourne in 1873 succeeding Ferdinand Von Mueller. He radically changed the gardens and made them more ornamental and scenic as opposed to Von Mueller's vision which was more of a systems garden. Below are pictures of the top of the volcano.
