ASGAP Conference: 29.9.97 to 3.1 0.97 I have started to keep track of how much water different Adelaide. plants use, I'm only doing the "waterwell" plants, and it has been quite interesting so far even though the rain we've had since the end of January has spoilt things a I have been asked, as have the other Study Group bit.

If anyone has any During the wet weather, I empty all the wells to allow photos of their container plants /collection that they the excess water in the soil to drain properly and wait could lend me I can get them copied and sent back until the wells are empty before refilling them. This to you, plus any other ideas, I would be eternally in seems to increase survival rates of any tricky plants. I your debt. As a rule I'm not very creative, my talents currently have 66 plants in "waterwells", plus others are of a more practical nature.

I COLOURFUL FOLIAGE PLANTS 14;- Most of the really attractive and colourful foliage plants lhave only grown this one in the ground but I'm sure it belong to the "rainforest" group. Some of them are too would be amenable to pot culture. Our oldest specimen big for containers, though you can grow them for a is 9 years old, it has beautiful flushes of hot pink new few years ,and then if you have room you can transplant growth that hang down and stand out like a beacon, the them into your garden, or give them to a friend.

Cuttings strike fairly easil) competition for light and nutrients. Some which I grow They have a nice photo of the plant on page 60, though in pots are Syzigium erthrocalyx, S. wilsonni, S. ours has hot pink new growth rather than the more wilsonni ssp crytophlebium, Lepiderema pulchella, reddish tone seen here. Agapetes meiniana, Acmena normanbyii (Syn: Acmena East Normanby River), Syzigium canocortex. I also have Acmena normanbyii some of these in the ground as well as Grevillea syn: Acmena sp East Normanby River baileyana, Opisthiolepsis heterophylla, Davidsonia pruriens, & var.jerseyana, Neolitsea dealbata, and probably some others that I'll remember next time in This lovely plant we've had for 3 years. We purchased down the back yard. I will be discussing a couple of it from Bryant's Nursery at Lismore where we always special favourites: Lepiderema pulchella, Syzgium call in on our way north. Kay recommended it to us and wilsonni ssp crytophlebium, and Acmena normanbyii. we've never been disappointed. It has beautiful flushes of bright red new growth for long periods that fade to maroon & its usual green. This one we grow in a 200mn Lepiderema pulchella waterwell type pot, and I've noticed it uses a reasonable amount of water, and depletes its reservoir every 2-3 If I had room for only one plant that can grow into a days. Pruning encourages the new growth. It hasn't small tree,then this would probably be it. Pulchella flowered as yet. Apparently it has small white flowers. means beautiful and this plant lives up to its name. We purchased our first one in 1988 and it is currently Radke and Sankowsky (3) have the only descriptor of about 4m high.lt gets very little care as such ie this plant that I have found, probably because one of fertilizer,and the Brush turkeys remove any mulch that them discovered it. we may put down.

Ours is about 1 m and pairs of fairly narrow leaflets. These leaflets are very bushy. It will grow in a protected sunny spot or bright,shiny green on the upper surface and taper semi-shade. towards the end. It has small yellow-orange flowers There are so many lovely colourful foliage plants, carried in densely flowered panicles during September - maybe some members would like to write in about their October. Ours hasn't flowered as yet that we know of, favourites. maybe it's not warm enough. The species is endemic to the Border ranges of N.S.W. and Queensland. Jones writes that this a beautiful species worthy of wider REFERENCES cultivation. Plants are spindly for the first few years,eventually becoming rounded and densely bushy. 1. Jones,D.L.
