Beautiful landscape there in France.

I'm only 900 ft here (and in a frost-pocket), but where I used to live in SW VA was almost your elevation -- ~2700 ft.

Surprisingly, first-frost dates were later in SW VA than here because cold air drained off the slopes into lower areas.

742ft. here in KC. We do ski on man made snow in the hills and valleys.

sluice...Denver one of my favorite places. The only downside is traffic grid lock.

Hi folks. Thanks for responding.I was just wondering how altitude affects climate and gardening conditions in general.For instance,we have great day/night differences,in winter but especially in summer.Even with our blistering heatwaves in summer,plants seem to enjoy the cooler temps of nighttime and it may well be that this makes the difference between succes or failure with some of them.I'm very tempted to try some japanese maples;I have a small plot at the back of the house wich in summer would only get morning sun .In winter this area is bright shade(if that makes any sense) without direct sunshine.Any suggestions?
Osprey looks down on all of us...
No-one below sea-level so far... Henk?

Sluice in Denver is the winner so far, at 1,600m to Osprey's 1,480m.

Doubt there'll be anyone growing conifers below sea level - not very good growing conditions. Well, maybe someone with Taxodium distichum at a metre or two below sea level in New Orleans, or the Netherlands. It would need to be Taxodium to cope with the poor drainage in such places. But the really low places (Dead Sea, Death Valley, etc.) are all in desert climates too hot and dry for conifers.

Were about 5-8 degree cooler than Denver ... almost never hit 100 in the summer.

Castle Rock, Co .. on the ridge above town
Elevation: 6500'

Mostly just native Ponderosa Pines in the area ...

Eastern Kansas at 1040' (317m) near the top of a North-South offshoot of a NE-SW ridge which tops out at around 1110'(338.33m).

Also, if you're in KC and at 742' elevation, you must be right down on the river (Kansas or Missouri Rivers), because most all of KC is in the 800'(243.84m) to 1100'(335.28m) elevation range.

Just under 1000 ft or 304 meters.
Eastern Wisconsin near the lakeshore.

Hi Sluice, Is Denver really at 1600 M altitude? T.

Also, if you're in KC and at 742' elevation, you must be right down on the river (Kansas or Missouri Rivers)

3 miles from Kansas River...about 10 miles west where the Missouri & Kansas rivers converge.

The 742' is for Kansas City MO.

The east has peaks too.
30 minute drive to slide mountain for me. Elevation 4,200 ft. Amazing cause my elevation is 279 ft. Quite a climb. -Werner J Stiegler

"Hi Sluice, Is Denver really at 1600 M altitude? T"

Denver = 1,609 m according to wikipedia. Presumably that's the city centre.

Definitely higher than I thought..

I like this site:
http://weather.gladstonefamily.net/site/AR193

We have similar weather stations located in the Lodi area. They are used by us grape growers to monitor temperatures for the prediction of Powdery Mildew, Evapotranspiration for irrigation. Hadn't looked at the site recently, seeing that it now has pest models and management guidelines for many crops.
Soil temperature too...wow!

It has the elevation at 23 feet.

Arctic ice melt being what it is, I think we should contribute some of our surplus soil to resin and Barbara so they don't get washed away.

Hmmm...the ice melt will solve our lack-of-water problems!

Hello tunilla

my garden is on + 13 meter or 42 ft

Hi Henk. Glad to hear it's 13 M ABOVE sealevel.As pinetree says,the ice-melt is worrying. I have seen a documentary about floating houses and gardens in Holland.Gotta move along with the times...and with the water level. T.

Hi Tunilla,

Henk en I live in the south-eastern part, the water doesn't come there so quick as in the other parts of Holland, so our conifers are also save then.
They are standing hi and dry hahaha!

Hi CJ. Not THAT dry,I imagine... judging by the pictures of splendid plants posted by Henk.
By the way,I noticed you run a Conifer-nursery.May we know some more about it,or have I missed out on something in the past?(I'm only a member since last August) T.

Kansas City Missouri, 860 feet/262 meters.

I have conifers at these extremes: FROM

near Silver City, New Mexico (here's the nearby elevation sign: http://www.waymarking.com/waymarks/WM3F8M)(a close competitor in elevation, which may be higher, would be Ponderosa, New Mexico)

TO

various islands on the Georgia, USA coast (Tybee, Harris Neck) with an elevation of, say, under a meter and

PLACES BETWEEN

such as Puget Sound, Washington State; New Bedford, Massachusetts; and Atlanta, Georgia.

To Resin's point, I do plant Taxodium and others that like wet feet (Dawn Redwood, Rimu, Glyptostrobus), but they are never lower than sea level because none of them likes salt water.

There are conifers that seem to be very tolerant of salty soil. For instance, Araucaria columnaris grows well right out on the rocky "islands" in the surf and are much splashed upon by the surf, but all the salt-tolerant conifers that I know of grow above water level.

Lowest I've collected conifers in the wild: Scots Pine Pinus sylvestris at 0.5m, Loch Shieldaig, west coast of Scotland.
{{gwi:635421}}

Highest I've collected conifers in the wild: Potosi Pinyon Pinus culminicola at 3710m, Cerro Potosi, NE Mexico

Tunilla,

Indeed I have a conifer nursery.
I produce about 1.300 differend conifers in pot and with a rooted ball.
Most of these plant are for export to north- and east Europe, this means that have to be very hard for these cold climats.
I also find some new varieties by meself but the best one till now is Chamaecyparis lawsoniana 'Filip's Golden Tears' which is a narrow upright form with strongly hanging sidebranches and the colour is a golden yellow.
I found this one as a seedling from 'Diks Weeping' which was standing in the neighbourhood of a 'Stewartii'

Hi Tunilla,

Are you near Gap?

Denver is 1600m approximately. The mountains visible in the picture (as well as Bunkers') reach upwards of 4200m or 14000ft. It does seem that altitude affects growing conditions, as conifers don't seem to survive here above about 3300m or 11000ft. Not sure why?

"It does seem that altitude affects growing conditions, as conifers don't seem to survive here above about 3300m"

Too cold higher up. Temperatures drop about a degree for every 100m higher elevation.

Resin

Hi everybody.
Coniferjoy,I'm beginning to piece things together.I first discovered your Web-site when someone on the forum directed me there to see an image of Pinus thunbergii 'Kotobuki'.I bought this plant at Hulsdonk nursery (NL) on their 'Collector's day';we turned up a bit late in the day as we had been attending a major European cactus-do in Blankenberge on the Belgian coast.
I wish you the best of luck with commercialising you new finds.
Arauquoia:Dutch folk would explain this much better,no doubt,but,nearly half of the Netherlands is below sea level.All water that acumulates here (rain,snow) is pumped up into canals (hence the windmills) and goes into the sea.
This is all non-saline water.Please note that Trompenburg Arboretum in Rotterdam (wich is on the North Sea coast),is only at 1,2 M (4ft) altitude.I cannot imagine the trees there having their roots in salt water.
Sluice; We're near a town called Digne (pronounce DIN-ye).This is south of Gap.
Actually,it's called Digne-les Bains,because it's a thermal cure town as there are sulphurous hot springs in the area.
Resin,I was wondering whether specialised metabolisms have been observed in certain conifers,like CAM (Crassulacean Acid Metabolism),wich allows succulents to open their stomata at night only,so as to protect them from exessive water-loss during the day when it's hot? T.

Hi All

Im 300ft/100m above sea level here in Devon uk.
Also anyone know the highest point in Holland?

I believe it is Vaalserberg near German border 322.7 metres (1,059 ft) above sea level in province of Limburg.

On below-sea-level conifers, a look on Panoramio found a few Cupressus sempervirens near the Sea of Galilee shores, at 209 m below sea level. Couldn't find anything lower down towards the Dead Sea.

Still reckon there's no conifers indigenous below sea level anywhere.

Resin

Ooooh...when at Resin's link in the post above, check out the aerial photo on the right; the agricultural fields are vineyards in the Golan Heights!
