Ornamental one year, invasive the next
Cydney Steeb column (July 17, 2013)
Betty doesn't garden on a grand scale any longer, but does take care of the houseplants where she now lives and gets out in the yard occasionally on cooler days. She pointed out a plant just under her balcony and asked me, "isn't that Japanese knotweed?" It was in fact its close relative, giant Knotweed which is just as invasive.
Keep your plants happy
How about those daylilies? I moved many of mine in the spring from a garden that was too shady for them, to gardens that get at least six hours of direct sun. They are much happier there and have put on quite a show to thank me for the move. If you have a plant that just doesn't seem happy where it is don't be afraid to move it. If it's still not happy after a year, google the plant and double check to see what growing requirements are recommended. If you have fulfilled the requirements and the plant is still not happy try moving it again. Many things can affect a plant such as heat radiating from a building, leaching from building materials such as creosote from railroad ties and lime, calcium and salt from concrete.
I took a liking to helleborus, aka Lenten rose, and planted two near my front door. One died and the other barely survived. I moved the survivor to a new location and it died. I decided I couldn't grow them at my home and was about to give up when a friend offered me four helleborus pups from her plants. She told me to plant them in different places to see where they might be happy. I now have several happy, healthy plants that bloom very early each spring. If you've tried everything and the plant isn't performing as expected, gift it to a friend. A friend gave me a Christmas cactus that refused to bloom for her. It had been a gift and she felt bad throwing it out. This gift blooms yearly for me.
