Siphocampylus

A Ben Kamm collection of this Bolivian Lobelia relative from rocky areas at 10,000'. This makes multiple upright stems 2'-3' tall with showy orange-yellow flowers that will remind your hummingbirds why they migrate to South American in the winter. Hardiness unknown but the collector speculates possibly zone 8a-8b and mulch most def for winter. Great for sun.
