The orchid is native to Eurasia and, as with many other species of introduced flora and fauna, the exact circumstances regarding its introduction are unknown. While the orchid is often found on the edge of woodland areas, we continue to see it as an opportunistic invader in lawns and gardens. We saw these pesky plants emerging in our landscapes in May in 2017 and can look forward to a similar showing during this year as well.

The physical removal of the plant will work to control it as long as all of the roots are removed. Otherwise, new plants will develop from the remaining root tissue. Glyphosate will kill the plant.

Always be careful with any pesticide use and read the entire label carefully before any application.
