It grows and spreads in my open garden here in the SE UK, with no special treatment. Flowers in (early?) summer. Lots of seed. Probably best amongst/high lighting other plants; a bit "thin" as a feature plant.

50 + years ago excavating beneath a greenhouse, loosely filling it with stacked bricks, and circulating air down through them, during the day to store heat and at night to recover was suggested. Electric house storage heaters, using a steel box full of high density bricks, and cheaper night time electricity was common. My bricks were used as paving later when we went over to gas. Heat stores/recovery systems, in boxes, or snaking through the garden, are still being promoted of course. We adapt, slowly, to whatever we feel is the most economic at any one time.
Many years ago I visited a contact to see his Nerine collection. One greenhouse had a rain-water tank/pond the full length of the house under the bench(s). It was populated with very many noisy frogs. Don't know if they were a good heat store ;-)

Many of the artificial lighting videos I have seen on tv show very limited wavelength lighting, often apparently just 1 or 2 narrow wavelength ranges. Is this just for edible/experimental products or does it apply to other commercial plant propagation? That's before considering light meter ranges.

Apologies. I saw it correctly when I was sending it, so thought it would be the same for all. It was a copy and paste from Google photo storage. I sent it to myself first to check. Needs more thought I see., Brian

So this is what it looks like ;-)

I have cleared an area  by removing Iris 'Jane Philips' which had stopped flowering. With a bit of soil amending it will now have a number of colchicums. The pot is 5" diameter.

Brian. Autumn started with sudden drop of 10  C in temperature.

I will try and find a suitable place for some in the garden. Colchicums don't get grazed by visiting wildlife. I have several of the larger specie/forms where the later leaves don't become a problem. Even some autumn crocus have survived this year although I have seen a squirrel investigating them. No deer for some months; maybe it is them normally who do the damage.

I now grow these, what a few years ago I thought of as a tender special plant, (before climate change) in my vegetable garden as a cut flower. These were recovered from my previous family home and go back 50/60+ years, so no longer named. I will cut the first this week; some leaves showing now ~15cms growth. Must weed out all the wild strawberries growing over them. They last some weeks indoors and usually produce seed too if kept after the flowers die off.

Brian, SE UK   sticky chalky stony soil. Maybe all this sulphur fallout from the volcanoes further south will change that.

Do you find C. baytopiorum increases very readily for you? In large pots I have maybe a 100 or more, but only get a few flowers every 4-5 years or so. Mainly I suspect because they get starved because of their rate of increase. Maybe I should insert into my rough lawn grass and see what happens. I currently have some buds showing in one pot, which I suspect were the larger bulbs I selected last season. At present I only have a few C. autumnale speciosum album, Waterlily, and C autumnale left in flower. The larger hybrids are all finished flowering.
It is fungus in the lawn/rough grass time here. All brown types with a hollow top; edible ??
Brian SE UK 17C today; again

I have built plunge beds in the past with angle iron legs and frame (fence posts) and 1" thick timber (ply or planks) bottom and sides. Then lined with heavy polythene or pond liner. Length needs to be limited to prevent "bowing" or use cross struts.

If you did Latin at school you would learn all syllables are the same length; so no long i's, o's, or anything else. Difficult at times when having a conversation about plants.

I was specifically referring to previous posting on Shiny Cranesbill, which does not have a taproot. Apologies.

I frequently pull off the growing centre of numerous plants, but have not checked if the fleshy roots reqrow. Am I fooling myself by not digging it up? As it grows in cracks and crevices it would be quite a job to remove all the roots.

Great plants and flowers. I grew this many years ago (last century?) from Australian seed I think. When regulations allowed such easy trades. Never got it to flower before I lost a quite mature bulb.

I find these almost indestructible as frost free greenhouse plants here in SE UK. (slugs allowing) Are their any more showy plants; maybe hybrids, that give more colour/flower size. I grow and flower H. sanguineus ok as pot plants but not tried crossing. Rarely see the other species available.

I have grown this for ~30 years or so. Original source(s) forgotten. When I had it in my previous garden/greenhouse it flowered every year, for some years. Super plant. I moved house ~8 years ago. All change garden/greenhouse/aspect etc. It's only flowered 1 or 2  times since being here. Still trying to find out what is lacking. I suspect I kept it moister when I first had it.
