Untimely warmth is dangerous- natives here are very conservative starting growth to avoid that risk, since we are guaranteed to have cold weather after warm weather in spring, but I'm sure exotics could be more at risk...

Been cold here in Reno about ten degrees below normal for us with little to no snow cover in the valleys. The cold air invertions have settled in so it didn't break the freezing mark in the last four days. It'll test the marginally hardy species. (about a dozen Aizoaceae I planted last summer) Should slowly warm up by the weekend.

Opposite for us, John- warm this week: well above freezing, even up to 7 oddly they just said on the weather that the only places warmer than Alberta today in North America are southern California and Southern Florida! Edmonton and Phoenix at the same temperature!..lol we'll be back to normal or below on the weekend..
Snow has an amazing effect on a garden - rather like comparing black and white and colour photos, but just with that hint of colour. Temperatures have dropped in south-east Britain to around -6°C, enough to stop much activity in the garden for a while. This sort of weather rarely lasts that long in the south, hence we have so many snowdrop gardens that open in February. Since we are opening for the first time this year in mid-Feb, touch wood it will warm up by then.

I garden in a relatively hot and dry region (for the UK!), with an annual rainfall of around 25", winter lows of -10°C and summer highs of 30°C.
Tim, We are sending another arctic tempest your way. It should arrive by the end of the month. Cheers!
Tim, it looks cozy ;D Although the temp here is about the same, we have just 1cm of "snow" and expecting rain in a few days.Michael, I don't want your arctic tempest >:(
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
Great views, Tim! Snow does really change things- no surprise- good time to really look at the bones of the garden!
Oops! -12 F morning of 1-24-13. Pffff -there goes Convolvulus cneorum (Southern Spain native). The photo indicates the weather here; frigid, sunny hot, snow cover -sparse, humidity as near zero as it can get. The plant is at the south foot of an enclosed porch foundation, certainly one of the mildest places on my property, so there may be some life near the base of the plant. The other plant is Muehelenbeckia axillaris (New Zealand native). It goes underground for the winter and the dead top growth insulates it as well. It's never failed to return in spring for many years. There's an Agave (Southwestern USA native), which still looks OK and assorted cacti here too. Weather here currently cruel to all living things.
Hope it pulls through! That's a chilly morning -12F/-24C For comparison, we haven't been lower than around -20F/-29C.
This week we range from nights of -14 to -23C (6.8 to -9.4F) and days from +1 to -14C (33.8 to 6.8F) - typical weather here, but we still haven't had the -30/-40 we could have over winter.. still a decent snowcover from nearly bare under some trees to a foot or so in open areas and several feet where it's shovelled...
After a couple weeks with cold dry weather (the coldest in my garden was -12C/10F) the milder weather is back. A little snow last night but it will soon transform to rain. What I am afraid of is the soil freezing deep and damaging the tender roots and bulbs when there is no snow cover and prolonged cold weather.
Bundraba, my Convolvolus cneorum died two winters ago. It doesn't like our wet winters either :-\
