Right, back again after the day of work, falling down for a bit to rest and read the forum. I grow Granny Smiths, and these are easily twice the size, bigger than a Sheepnose or a Pound Apple, with a very pronounced crown (that circle of five little knobby points at the base of some apples), and no russeting. Also a brighter, shinier green than Granny Smiths. I intend to take some back to show to my fellow Rare Fruit Society members and try if I can get a firm identification.
Victor Harbour has some amazing plants. At the place where I was working today, one of the pioneer gardens from the early settler area, the original owner planted a row of Norfolk Island Pines intended for ship masts. They are huge, now, and very beautiful. Going back there for part of the day tomorrow.
It has been an interesting trip. Two days of paid work, teaching bushcraft and foraging and propagation and growing techniques for native wild food and fibre plants, and two days of voluntary work, identifying and salvaging the plants in a couple of old gardens that are slated for demolition, and teaching the local Gorsedd their letters and trees. Exhausting but fun.
