Please ID this succulent and its hardiness zone, I'd like to know if it can be left outdoor over winter in Zone 5 Canada. Both plants were planted at the same time 6 weeks ago with the inset picture grown indoor. Both are about 6 inches tall but as shown in the picture the one grown indoor is leggy but with shiny leaves. The one left outdoor in a shady location looks healthier and happier.
Sorry, the answer without even knowing the exact species and variety is a solid NO. These are desert plants. I am glad the one on the left is in the shade out of doors. You have to pull these plants back indoors BEFORE the temperature drops below 40! If they were in the sun you would have to re acclimate them back into the indoor environment. I take all my indoor plants out for the summer season under a roof or cover. They get far more light that way, make more food to last the winter in low light.
Your plant on the window sill is in a pot with no drainage. Or is there a hole in that pot? Succulents, desert plants have shallow root systems. Those roots have to suck up water whenever the desert gets a rain and then they STORE that water. Pots any deeper than 6 inches can be a concern if you water too deeply.
Your plant on the left looks as if it is in the sun. Is it? You had better start bringing it inside for an hour a day for 3 days, extending the time to half a day before bringing it in for the winter. What are you doing for fertilizer, better yet what soil have you used in those pots? I hope it was potting soil, not garden soil? What are the temps at night? I'd be bringing them in every night now anyway!
No these plants are not meant to be outdoors in Canada for the fall or winter and some of the spring! Grins...
An aside, since these plants require so little water, please go find a bottled water without fluoride or better, find a friend who has well water and borrow some. Tap water is awful stuff that we shouldn't be giving our dogs, cats, babies nor ourselves!
