Although there are not as many larch species as maples, the lace where they naturally grow can be of some importance. I only have Larix x eurolepis (= Larix x marschlinsii), aka "Dunkeld larch", a natural hybrid between the European and the Japanese larch. I suppose that "tamarack" would be the best species where you are : ? I LOVE Larch : they are conifers, but behave like deciduous, with all the range of colours through the seasons.
The commercially prevelent weeping larch is weeping Japanese larch. It is sold as weeping European larch but in addition to having Japanese larch foliage and shoots it even produces characteritic Japanese larch cones on less than large specimens.
