Indian summer plant

Hi, I got 3 very small indian Summer plants , I have looked after them indoors and now they are healthy about a fit tall. Should I leave them indoors, or plant out. If I plant out will they die down and reappear next spring? Thanks

    Alstroemerias are almost hardy. My Indian Summer lives in a pot with no protection and does well, but if we get a very cold spell I will put it into the greenhouse or even bring it indoors. I have not grown them in the ground, they would need a layer of mulch, at least in a cold winter. I don't think many people grow them indoors, they will do better with sun, so I would move it outdoors, and also put it in a bigger container!
  • Thankyou for your advice. I will plant them seperately in pots, and let them get used to outside weather.

    I agree with Alan, Alstroemeria Indian Summer is an outdoor plant, hardy down to -10c so can be left in the ground unless you live in a very cold area. I have a slightly more tender one, my winters are cold, down to -8, but that one survives outside fine. Small young plants can be hardened off by putting them outside during the day, from around May, then planted out a week or two later. They have grown a bit soft and leggy being cosseted indoors, so for that reason I probably wouldn’t risk them in the ground at this late stage, but do get them potted up and outdoors. They are perennials so will die back in winter whatever. Are you sure they are Indian Summer though? That usually has darker, bronzy foliage, my more tender one has green foliage..

  • Thanks, for your wise words. I bought them as Indian Summer plants from reputable online store. So I belive that they are.

    They probably need more sun to go bronze.  Grown indoors they'll be short of sunlight for photosynthesising and more likely to stay green.

  • I leave mine outside in the ground all year here in the East Midlands and so far they have proved perfectly hardy, although much smaller plants than I expected compared with older varieties.
