This is a bushy plant I have seen twice in Toronto and that no one has been able to identify for me. I wonder if you can help! It has frothy long green stalks that turn pink at the ends. From s distance it resembles a pink Russian sage.
The plant is most likely a Tamarix ramosissima, also known as Tamarisk or Saltcedar. Native to dry areas throughout Eurasia, this plant has become naturalized and is considered an invasive species in the drier regions of western North America. It was introduced as an ornamental shrub to North America in the 1800s. In areas with cold winters, it does not become invasive.
Tamarisk are unique with their long, graceful and feathery arching stems with sprays of pink flowers, providing an ethereal appearance in one’s garden. Given the right conditions, it will grow rapidly. Once established, pruning in the late winter will keep the plant compact and produce the new growth that will flower.
