Dear Mike, Like others I appreciate all the time you have spent on this and think it will be a great resource. Perhaps another option so all of us could read the keys would be to use a font that works on all platforms. If the pdf file gets too big for our wiki limits Nhu, David, or I can transfer it in. We allowed a couple of Lee's maps with larger file sizes. If they were smaller, making out the details was tricky. And I think at least one of the maps with a large file size, Nhu added a smaller version too so that you had a choice whether to download the larger version if you had a slow connection. I think perhaps we should create a climate wiki page linked to the home page and they link your page and Lee's two pages to it. I suppose we could also link all those discussions we had a number years ago when we did the topic of the week on which bulbs to grow in different climates/areas. Like Bracey I think the issue is very complicated and that knowing as much as you can about where the plant grows naturally is helpful. We've talked before about when to start watering dormant pots. Although Gordon Summerfield in South Africa who has grown many South African plants suggested that we could wait until October in the northern hemisphere, I've found that is too late for some things. If they aren't started into growth earlier like they would be in South Africa, they don't always bloom. Perhaps they need a certain length of time to grow before they will bloom. Whether dormant pots need to be watered in the summer in dry areas may also depend on whether the "bulbs" (all inclusive term) continue to have roots during dormancy. If they do and the pots dry out too much so that these roots dry up completely, the stress may be so great the plant is always struggling to recover. On the other hand if every year the plant produces a new corm or a new rhizome, it may not matter as much. Now that I water my Nerines in summer they flower much more frequently. But my Romuleas seem to do fine without summer water even if they are exposed to rainfall in South Africa in summer. Because of the font problem I can't look at all your data, but can Australia really be described as having a "milder" summer? I thought temperatures got really hot in summer in a lot of the states except for Tasmania. I grow a lot of Australian plants successfully with little summer water and live in on the coast so that fits your theory. But just because we have cooler temperatures and some fog, if you dig down in the soil much below the very top, you find it is absolutely dry in summer. Having a lot of Coast Redwoods means their roots are soaking up any available moisture. I look for plants to grow in my garden that come from areas with low nutrient soils since that is what I have and I think that is one of the reasons I can successfully grow a lot of South African and Australian plants. I find that Western Australian plants (often considered to be Mediterranean) don't last long in my garden however. I've always thought they needed more heat in summer or that it was too dark and wet in winter for them. Besides the Arctic Express problem that can wipe out collections of people who live in areas where usually it doesn't get cold, but can on occasion, there are also the El Nino factors. For a number of years we have had a "drought" where I live. Our droughts mean that rainfall could be between 30-40 inches (76 cm-101cm.) This stresses the trees and plants used to more rainfall, dries out the rivers in summer and is not good for the wildlife. But it is still a lot more rainfall than naturally occurs in some of the areas where bulbs I grow originate and a lot of them grow much better in a drought year. If you have a year like this one where we seem to be getting some precipitation almost every day lately some of the bulbs that are happy in the drought start to rot or the leaves get grey mold. And the lack of light means others are getting floppy. Thanks for taking this on. You've added information to the wiki that will be very useful to a lot of people including all your cultivation information too. Mary Sue
