| Just thought I would share...
After two years of trying, I was able to grow cardinal flower from seed. The seedlings were very slow growing. I just planted them out on my riverbank/seasonally flooded area. I am a little worried about them making it through the frosts, but it seemed better than keeping them in my greenhouse over the winter. Most seedlings were pretty big. I still have one flat of tiny seedlings. I am trying to decide whether to keep them in the greenhouse or plant them out. My greenhouse is not heated. Thanks for all the encouragement and advice. |

| the ones planted outsid should survive the winter...... As for the flat best to keep in greenhouse. make sure the soil stays damp all winter & cover with plastic, straw, or leaves to delay evaporation of the water..... but hold off till the seedlings tops are dead...... |

| I winter-sowed Lobelia cardinalis in winter 2008, got many seedlings. Planted some and potted some in small pots. The ones that were planted out were promptly eaten by slugs, because that summer was SO wet, but the potted ones did well over the summer. I finally planted most of those out on November 7th (yes that is pretty late, but I keep detailed records and that's what the spreadsheet says!), leaving about half a dozen in small pots. All the Cardinal flower seedlings did fine over winter 2009 and bloomed well this summer. So, in my experience this is a pretty hardy little plant, tolerating colder and drier conditions than I expected. This year I noticed that the Cardinal flower in my hummingbird garden has also self-sowed here and there, so there is lots of it for the Hummers next year. :) |
