They are beautiful and real show stoppers .. when I grew them a few years ago I had people knocking on my door wondering what they were. They are suppose to be hardy in zone 8 but they never came back for me .. I like the fact they bloom from seed the first year .. if anyone wants seeds, I have elebendygazillion of them - they are hard coat seeds and stay viable for years.
You're welcome! Never though of them that way, as harbingers of cooler weather but you are most correct! Lol .. the harbingers of cooler weather for me are having to set my automatic timers for my lamps inside the house back every few weeks.
Have a feeling our GH's are going to be crammed with tropical 'stuff' this winter. If there's any winter precip, I'm hoping it's a brief snowfall instead of a crippling ice storm. I'm thinking about getting a kerosene heater for my GH just in case of a power failure.
Other indicators of summer waning are out of control morning glories, pampas grass plumes, and spider webs everywhere that I usually wind up wearing during my morning walkabouts.-)
I don't think a kerosene heater would be a good choice for the greenhouse unless it's a really big one .. they put out tons of very dry heat .. I use one in my living room/computer room to save on electric (though the cost per gallon of kerosene keeps creeping up - almost 4 dollars a gallon now) and it can get my living room and computer room about 35' x 15', over 90 degrees in about an hour. They don't come with thermostats either.
I just did some checking and there are small kerosene heaters available but I can't find any with thermostats and you might even consider propane as well - they might have thermostats. I don't know.
I've found that passive solar heating helps a bit .. merely take some 2 ltr soda bottles, paint them matte black, fill with water and lay on side .. collects heat in the daytime and releases it at night. I put all my extra tropical hibiscus on top of the bottles .. I've found that pretty much all plants will tolerate temps in the upper 30's with no lasting damage.
I'm definitely going to use the passive solar method you explained. There was a terrible ice storm here in 2005, almost a year before our move. My father and everyone else around here were w/o electricity for almost 2 weeks! Must check out the small kerosene heaters - seems like I've read that plants like the carbon dioxide(?) they produce. Must make certain that my GH has proper ventilation. Thanks!
Hi I am newbee to Dave's Garden and I love beautiful plants outside as well as indoors. I live in Asheville NC and I thought if you have any extra seeds I would love to try this beautiful plant here. I am more than willing to pay you for any and all seeds that you might have to spare. Thank you, Kitteney
Okay, this is embarrassing, kitteney, but I lost all my seeds to a light freeze last fall - for the 2nd year in a row the seeds in the pods were mush by the time I got around to collecting them. 2 weeks ago I dug up a few, and put them in on my backporch, but they're not looking happy. In fact, they're looking dead. Still, hope springs eternal, and I've moved them to a sunnier spot and have high hopes for a recovery. There are some very generous folks on this forum and others who would share seeds for postage.
Know what you mean, Barb, these plants really do take up a lot of real estate. But you get to breathe the fresh salt air and not worry about killing temps below 20f.-)
Your Senna are outstanding, mine just got started this year, one of the very few plants that gives you great winter color,my pride of barbados didnot bloom this year so no seeds for next year,still have summer plants in bloom,mexican heather,gerba daises,and soft caress mahonia as well as rose verbena,and others guess its been a mild winter here on the island
Its an evergreen tropical shrub,cold hardy to 30 20 ,as i said this is my first year hope it will look like donascreation,since ive got different micro climates on my five acres on the island,different plants make it,many of my new plants such as senna I plant in large containers to see how they thrive.also because one third of my gardens are subject to huricane flooding,and the seem to servive better.Will know better next year after I transplant this in an area where it can spread as I understand it reseeds itself.LOL Walt
They rarely come back here either. X, the ones you sent me 2 summers ago did come back because last winter was so warm and we never had a freeze but that was not the norm. Most consider them annuals around here (zone 9) and start seeds each year.
It may be that they do better on the west coast where the zones are the same but the growing conditions are so very different.
