Lophospermum, Creeping Gloxinia, Mexican Twist 'Great Cascade Wine Red'

I have a question for those with experience with Lophospermum. I bought a Lophospermum hanging pot, full of buds and blooms. Beautiful pl...Read Moreant. It’s advertised as self cleaning and sure enough each bloom falls to the ground when spent. This leaves the calyx behind with the ovary inside, sort of like a Petunia does (hope I have my terms correct). Each calyx seems to have a firm ovary in it which on inspection looks similar to the seed pods that follow spent Petunia blooms. As long as the Petunia seed pods are in tact the plant devotes energy into seed production. My question is would removing the numerous calyx on each Lophospermum tendril help stimulate more flowering on that tendril or should you clip off that tendril to promote new tendrils with new buds and blooms? Also, despite numerous reddish tubular blooms, my Ruby-Throated Hummingbirds appeared to ignore it. Thanks for any assistance and any comments.

I bought this plant last year at a plant sale in Brooklyn. It did wonderfully throughout the summer and fall in my skylighted hall area (...Read Moresoutheast exposure) blooming profusely. I kept it there thru the winter when temps reached 55-65 degrees. I reduced watering and only watered from the saucer, afraid of stem rot. This year it did not fare as well. What I have now is smaller leaves mottled with white streaks and alot less flowers.

I plant several of these vines in a long windowbox located over a high entrance archway. It hangs down in great swags, so that its like w...Read Morealking thru a curtain. fast growing and gets progressively more floriferous as the season wears on. The flowers are a rich vibrant burgundy and resemble gigantic snapdragons. It needs lots of sun, regular watering, and periodic fertilizing. I combined it with variegated vinca vine, and hot pink cascading petunias.

I bought this plant at a local nursery here in North Pole Alaska; for the first time this spring. It is now my new favorite. It bloomed f...Read Morerom mid-late June through yesterday (Sept 8th); through several frosts, and had blooms still coming as of Sept 8th. I will have to check and see if it survived our coldest temperature to date 25 degree; last night. I used bat guano, plant food, green sand, and bone meal, when I transplanted it from the small 6 inch pot. I first had it in full sun, after the first few blooms it seemed to stop doing anything, so I moved it to my deck which is part shade; getting only direct sun in the evening, from the time I put it on the deck it was non stop beautiful cascading from a tall stand, all the way down, and spreading all over the place. I did have to keep an eye on the vines, and keep them from tangling, and choking it self out. Our summer was very rainy, but it did not seem to bother it as it did some of my other flowers. I had it planted in a 24 inch pot which was about 17 inches deep, along with a Fuchsia planted with it. Was hoping to hear I could keep it some way over winter; but I guess I will try the cuttings, and see if I can find out where the seeds are. Thanks!
