The State Library of Victoria has a brochure from c. 1911 of a plan of the Botanic Gardens precinct gardens, including Alexandra Gardens (or Park as it was then known)

Botanic gardens:Photo-lithographed at the Department of Lands and Survey, Melbourne, by W.J. Butson; drawn by F.S. Hilcke, c. 1911.
One of the most, attractive sights in Melbourne just at the present time is the glorious display of flowers just across Prince's-bridge, at the entrance of the Alexandra-avenue. The roses are past their best, but the dahlias, chiefly of the cactus and decorative sections, are in their prime. Single dahlias are not appreciated by everyone, but a large yellow variety here is really a good thing. Cosmeas are in profusion; their light graceful foliage and showy blossoms contrast well with the heavier appearance of the surrounding plants. Bonfire Salvias are a blaze of dazzling scarlet S. azurea is rightly named its colour being a heavenly blue ; S. Grahami purpurata is a rosy shade of crimson. Golds and yellows are found in Rudbeckia Golden Glow and some of the dwarf Helianthuses. Cannas are a little past their prime, but Bouvardias, Lasiandras, Marguerites, and several other autumn plants ate at their best. Palms, grasses, Aralia papyrifera, Dracænas, Yuccas, and many other kinds of foliaged plants are judiciously interspersed here and there amongst the banks and beds of flowers. Signor Catani of the Public Works department deserves very great credit for the manner in which he has designed and laid out the ground. it is indeed a choice bit of landscape gardening. For many years this spot was a desolation and an eyesore; it has been converted into quite a fairy-like place, full of beautiful flowers and shrubs, rockeries, and well kept lawns, and all within a few minutes' walk of the Melbourne Town-hall.

This shows some of the garden 'just across Princes Bridge', as the article above described. It is not the best photo - but I like it as it is a post card sent from Clara to Daisy - "Dear Dais - We are having a good time with my uncle, aunt and cousins. We are never home. We have a servant coming on Saturday, so we will be able to enjoy ourselves much better. I wish you were down, from Clara"
Dais was Daisy Donaldson and the card was sent in 1905.
Even though, Carlo did deserve much credit for this dazzling array the head curator, George Cooper, deserves much credit. You can read more about George William Cooper, here. This great tribute to Mr Cooper comes from The Leader of May 4, 1912.
The Curator, Mr G.W. Cooper; is prouder of this achievement that when he is praised for the very beautiful color displays, which are to be see at all seasons of the year in the beds and rockeries. Mr. Cooper is a son of the foreman of the Melbourne Botanic Gardens, and the results of his work, now under notice, stamp him as one of the best of the younger generation gardeners in Victoria. The all-important factor of enthusiasm is behind this excellent example of public gardening, and Mr.Cooper's untiring efforts receive full encouragement from another enthusiast, Mr. C. Catani, who as Chief Engineer of the Public Works department, is the officer responsible for the maintenance of the avenue, which ends all too abruptly at Anderson-street.

One area of the gardens was the Henley Lawn where spectators by the thousands lined up to watch the annual Henley-on-Yarra rowing regatta. The lawn was laid out by Carlo and George Cooper in Autumn 1908. You can read a history of the Henley-on Yarra here, on the Australian Henley webite, http://www.australianhenley.org/history.html

One of the features of the Alexandra Gardens is the Federation Star Bed, also called the Commonwealth Star bed. It was designed by Carlo and George Cooper and on July 11, 1906 was planted out with 200 roses by the National Rose Society. The bed consisted of a six-pointed star representing the Commonwealth with interposing circular beds signifying each State. Each State was represented by a different colour rose. Read my post on the Federation Star bed, here.
