I have had this plant growing outside for 3 years, it freezes if we have below 40 degrees, (Fl. zone 9) but comes back. Mine is starting to leaf out now. I planted some of the seeds and when I put them in the damp soli they exploded, like pop corn, never had that happen before. They have not germinated yet, it has been 4 weeks. So they may not.
I will keep you posted.

This cultivar is smaller and more compact than the salmon-colored traditional crossandra. I got my seeds from Seymour's Selected Seeds. According to the catalog, the blooms are lighter in tropical and semi-tropical climates (as opposed to houseplants, I guess).
So far I am very pleased with the self-branching habit and glossy attractive leaves that enhance the bright yellow blooms. Each bloom is shaded darker in the center. I don't know yet if it will come true from seed.
