Gleditsia triacanthos var. inermis ‘Impcole’
The Imperial Honeylocust is a favorite of ArborAdvisor – it’s essentially the perfect tree for Colorado’s front range. This tree has a beautiful rounded shape and is a great lawn tree OR street tree. In the spring it has yellow and white small flower strings which provide a nice fragrant scent. It has thin fern-like leaves which provide nice filtered shade all summer and then turn a lovely golden yellow in the fall. This tree does so well in lawns partly because it provides a filtered shade that allows the grass and other partial sun plants below it to still grow. Also, when these leaves fall in Autumn they so small that they don’t need to be raked! They aren’t big enough to hurt the grass below them. Another great thing about the Honeylocust is they drop their leaves earlier in the fall which keeps them from being damaged by early Colorado hard freezes and heavy snow. The tree is native the the United States and has been bred to be extra hardy. It holds up well in urban environments where there is air pollution, salt, soot, and varying soil types. All this tree needs is a full sun location and occasional watering (especially in the first couple years after planting) but otherwise it is an extremely low maintenance tree. This is a fast growing tree so you wont have to wait decades to see a beautiful large tree on your property. It’s roots stay well below the surface as well, so no worry about pushing up the sidewalk or creating trip hazards in the yard. Unlike other honeylocust varieties which have thorns and large seedpods this variety has neither. The Imperial Honeylocust is both thornless and seedless. This tree is slightly smaller than the Shademaster Honeylocust and will grow to be roughly 40 feet tall and 30 feet wide at maturity.
