Answer: Laurentia axillaris was introduced in 1995 by Thompson & Morgan. The original was 'Blue Stars'. Now the series includes a white-flowered 'alba Shooting Stars', and a 'Starlight Pink' which boasts lavender-pink flowers.
Seeds for all of the 'Stars' series are available from Thompson & Morgan, PO Box 1308, Jackson, NJ 08527-0308. Phone 800-274-7333.
I don't doubt you've looked high and low for information. Laurentia is also known as Isotoma and Solenopsis! Leave it to the botanists to confuse the gardeners!
