you are right about the first one it is a stetsonia coryne i rescued mine from a walgreens pharmacy since i got it it has grown about three inches (i bought it around christmas 08) good luck

I have heaps of succulents to trade or will send for postage costs

I am sure that you could grow many of the less tropical Heliconias in Sydney, particularly if H. angusta does well there. To add to the list of the more cool-hardy Heliconias to seek out, these have all done well for me in northern California coastal conditions, where we do occasionally get colder than you... I never had much luck with growing any of the H. angusta cultivars as outdoor specimens here, and I think it was our lack of summer heat and a little too cool winters, they didn't seem to like it below 12C, and that is right around our typical summer night temps, so they never really took off, but also refused to die. H. latispatha, H. spissa, H. bougaeana, H. matthieseae, H. aurantiaca, H. scheideana All of these come from higher elevations of southern Mexico into Central America, and will take some frost and cool nights just above freezing without damage. However, none of them are the classic tropical looking species with really large flowers, except that H. bourgaeana does come close. There are certainly more species that are worth trying as well, but these would be a good start. As to gingers, there are also many of the Hedychiums that do well, with H. gardnerianum, H. flavescens, H. flavum, H. greenei, H. densiflorum, are fairly common and do well in subtropical, warm temperate climates. Of the Alpinias, A. zerumbet and A. zerumbet variegata are two of the easiest here in northern California.

Did you find any.
