Invasive Alstroemeria

    I’m wondering if we’re talking about the same plant, this looks so inoffensive sitting here, although it did take  over in my daughter’s garden.

    Gardening on the wild, windy west side of Dartmoor. 

  • That looks like it, tho the leaves and flowers are paler on mine. Maybe there are less invasive varieties?

    I am struggling to grow this from tubers as plants are very expensive. My daughter loves them. How strange to hear it described as almost a weed
  • To those who are wishing this would grow, do not go there! I live in Shetland, 60° north, it’s windy nearly all the time, often very windy; if the temperature in summer reaches 20°, it’s exceptional, we’re too hot, and speak about it for years. This sets the scene. 

    My dear late dad gave me a wee bit of this plant (lovely deep green leaves which grow in a kind of spiral around the stem, topped with orange Lilly like flowers).  He did ask if I was sure I wanted a bit! First I put it into a flowerbed with deep, fertile soil, fairly shaded, rather damp.  It took over in one year! Completely! About year 3, I took a large tarpaulin, dug out the whole flowerbed, sifted through all the soil and removed every single little bit of the rather friable white roots, before putting the clean soil back.  So far so good.  This flowerbed is okay now.  

    But! I do like this plant, so kept a tiny wee bit to put into a small enclosure at the south gable of my old croft, where there’s no depth of soil; it’s dry and stoney, extremely difficult to plant (or grow) anything (I used a 6’ long iron pinch bar, for making fence post holes, to make a hole to plant it in). I thought it would be fine to have a little bit of alstroemeria there where little else will grow, but I was wrong! It is extremely invasive, I strim it to the ground every year and still it’s spreading til I have hardly any grass area left! I don’t like using chemicals, but am investigating what I can finally rid myself of this evil plant.  My late father’s garden was beautiful, it is now completely overrun by this plant.  Also in Shetland, so this plant when it grips, will stop at nothing!

    Don’t be tempted!

    My son had the orange one in his garden@janemanson and it was hellish to get rid of. After 3 years he's managed it but he's convinced it will come back.

    There is a wild type I have often seen in Scotland, which is fairly rampant, it is not the same as the cultivated varieties, although I have one which is steadily spreading.
