Hello, I keep telling myself that I'll keep up to date in reading the postings... Lobelia laxiflora is in the trade in California and I've seen it listed in the Pacific Northwest as well. However, the selection in the trade is L. laxiflora angustifolia. The flowers are the same as those pictured, but the foliage is lanceolate. And the internodes are short. In my garden, it grew to 30" (70cm?) tall and bloomed late spring to mid summer. It is rhizomatous and will spread far in time. I've seen it growing through a hedge and becoming an ineradicable element in the garden (read: weed). I've been told that it blooms non-stop in barely irrigated sand in San Diego. The stems are frost sensitive in wet, Northern California winters, though the roots seem hardy. I've seen the form listed in the Plant Delights catalog while traveling in southern Mexico, but never the selection that is in the trade. I have trouble imagining the lanky form in a garden, but it might settle into a casual, "wild" garden attractively. Brook
