Acer x pseudosieboldianum 'North Wind' Broad green upright. From Iseli Nursery: "North WindÂ® is the flagship member of the Jack FrostÂ® Series, bred by Iseli Nursery to tolerate harsh and dramatic weather shifts that occur in many regions of the country. It has been unscathed at Iowa testing locations including winter temperatures of -30Â°F. The palmate leaves emerge red in spring changing by midsummer to green, followed by a dramatic orange-scarlet in fall. " I saw this tree at a nursery in the spring, and you could see it from across two lots. Bright coral, shrimpy red. It was gorgeous. While I was looking at the six or so specimens they had, one was carted away for the big arboretum in Madison, WI. Two others were tagged and sold. The nursery said they were flying out. I couldn't afford the larger trees at that particular nursery, so the folks at Iseli looked at who else was shipping them in to our state, and gave me the name of a few nurseries selling smaller sizes. A long drive later and there's a North Wind in our yard. Our tree is planted in solid shade and stayed green throughout the summer, then turned yellow with green veining, then flushed bright gold with tips of red and orange. Very pretty. My friend who had it in a sunnier location reported a second sprout, mid-summer, of the coral-red leaves. I added an updated photo of the tree/form after three-plus years. The cultivar puts on an incredible show each fall-- starting with yellows and peaches, then getting very bright orange and red, with hints of yellow. I like this tree a lot.
