'Falling Waters' Mangave is a recent cross between an agave and a manfreda, created in 2018 and quite amazing! Its blue leaves are covered with faint spots that become more pronounced the more sun and heat this plant receives. The thick, toothed leaves naturally drape downward, and can be put to best effect in a container planter. If you are a rare plant collector, this is definitely one you'll want to have in your collection. Though hardy down to 20 degrees, best to keep this gem safe from frost in the winter.
