I found S. oxphora at Georgia Vines for $10 + $3 shipping for a "Starter Plant".
Was going to get a 1 gal from Flowers by the Sea, but couldn't justify
$10.50 + $21.50 shipping though I'm sure it's a very good plant.
According to HerbCottage Dotcom in Australia, "No plant has been observed with seeds after flowering, either in the wild or in herbariums."
I'm not convinced, and will try to get some anyway, IF the plant thrives.
If it grows wild, how does it reproduce if it doesn't produce seeds? Unless it layers or spreads through
the soil?
