I've never been able to keep a Linaria alive over winter, but I did find one that came back from seed: Linaria aeruginia var. nevadense. I'm not sure if that's a valid name, but the grower assured me that's what was written on the seed packet. This Linaria is an airy sort of plant, with thin stems and gray leaves, and is hard to see until it produces little snapdragon-shaped flowers, which it does from early summer to late fall. The grower had plants flowering in various shades of red, from which I chose a dark purple-red, and most of the seedlings retained this color. I planted it in 2006, and seedlings flowered every summer for the next 5 years. I suspect its failure to appear after that was due to lack of open gravel for it to seed into, as creeping thymes and other plants had grown over all the open spaces.
