Here I offer seeds from Lobelia tupa. As you can see the Hummingbirds love this plant. Lobelia tupa likes dry soil and full sun. It just can not get too much sun. This plant is native to central on down through south Chile. The 2 lipped blossoms are totally tubular, no really they are. I love this interesting flowers, but all parts of this plant are poisonous as is the case with most tropical plants. On the plus side it is very deer resistant. These put on quite a show late in the season when you need it most. USDA Hardiness Zones 8 to 10.
