Sometimes “pretty” can be dangerous, Kim. Like roses with their lethal thorns. Rest assured, we were snowballed by alstroemaria’s beauty to have planted a number of plants in our garden almost 20 yrs ago. Regretting our actions now so thought it prudent to share the warning on how difficult they are to get rid of. Moral of this story is to buy some altroemaria stems from the flower shop whne you want to admire their beauty and keep the plant roots out of your garden.
