Penstoemen and Lobelia Cardinalis?
Comments (5)I have both Penstemon 'Husker Red' & 'Mystica' in my garden beds and love both, as do the bees. Both were grown from seed via winter sowing and have thrived since I planted them out (in 2010). I don't pinch or prune my plants--in my experience they're entirely care- and worry-free. I'm particularly impressed with the fact the foliage of P. 'Mystica' not only came through this horrid winter but did so with both its color and form undamaged. As for how to care for them, if you have healthy soil, they should prove virtually carefree. I've never done more than prune the seedheads in late fall & collect the seeds. If you're a stickler for appearances, the stems could be cut back I suppose. I just leave them standing through the cold months and cut them down during Spring clean-up. Where I am Lobelia cardinalis dies back completely in the fall and disappears until it shows itself again the following growing season. After several years in my garden beds, I can honestly report it has needed zero attention or care from me and has not been bothered by any predators, vermin or insects....See MoreLobelia cardinalis native/McAlpine park
Comments (6)Thanks for the pic. My husband innocently cut mine down a couple of months ago, but I kept it watered and it came back nicely. It has several bloom stalks now instead of the original one; what a treat. This is one I bought fron NCNPS and planted near the house. There "were" some along the creek, too. Also, there are some growing in a natural wetland visible from the entry to Elon University's football stadium, in case anyone's here this fall, keep an eye out. they usually bloom about a month....See MoreWhat eats Lobelia cardinalis greens?
Comments (6)Both woodchucks and rabbits have bit plants off near the base here to eat the plant on the spot or drag it off with them to eat elsewhere. Of course sometimes they decide after biting off the plant that they really don't want to eat it. The rabbits did that with my gas plants. Left the nipped off plant carcases for me to find. You'll need to watch or examine your plants more closely to determine exact causes. You can protect them with barriers of some sort to discourage the non-insect pests. Insect pests need hand-plucking and squashing (what I do) or some sort of insecticide. FataMorgana...See MoreLobelia Cardinalis[Cardinal Flower]
Comments (28)I have found colonies of this plant, in the wild, harvested their seed, and hope to expand their grounds. Said colonies are streamside, and most often UNDER water in the winter and spring. I plan to carefully remove plants for my water's edge (same river, just down-stream), but am undecided regarding the best time to so-extricate. Much of my concern has to do with which rosettes are best to harvest, ie., the single plant rosettes, or those with 'babies'?? SO MANY large rosettes this spring, and I wonder, did they similarly exists last fall?? As mentioned, I have harvested seed (last fall), probably a quarter pound of said seed, and will be curiously scattering it in places which are wet, but likely have not been so fortunate to have seed ever reached there. The seed is so small, has little likelihood of being carried by wind or birds. This should be interesting and fun....See Moredirtgirl
