Q.Star of Bethlehem
I cannot believe you wrote an article promoting this bulb/plant or even suggest planting in woodland. This plant is highly invasive and a nightmare to gardeners. It will take over your garden and lawn. You should take down this article so inexperienced gardeners don’t get sucked into planting this. I spend hours every year digging it up so it does not take over my flower beds!!!!!
Keeping this plant in a container does not stop it’s invasive behavior. If the seed heads are not deadheaded IMMEDIATELY, the seeds are in the wind and germinate EVERYWHERE! Do not plant this flower!
We do offer information regarding the invasive quality of Star of Bethlehem and offer suggestions for gardeners to keep the bulbs contained.
