27. Purple Loosestrife: Looks Lovely, Destroys Wetlands
At first glance, Purple Loosestrife seems like a wildflower dream with its tall spikes of magenta blooms. But don’t be fooled—this plant is a ruthless invader of wetland ecosystems.

What starts as a shade tree becomes an ecological headache.

Bottom line: this plant is bad news from root to bloom.
30. Kentucky Bluegrass: Not Mountain Material
Kentucky Bluegrass is the poster child of suburban lawns, but it just doesn’t cut it in the Rockies.
It’s water-hungry, shallow-rooted, and doesn’t play well with drought or native species. In high elevations and arid conditions, it demands constant maintenance and irrigation.
Meanwhile, native grasses thrive with less and support local wildlife.
Go local, skip the thirsty turf.
