About 20 years ago, my dear friend (now passed) offered a few stems of a purple spiderwort that had been in her family for over 50 years. We loved the plant and it thrived so we now have an abundance.
About 3 years ago, we noticed a few white blossoms among the purple. Those stems have continued to bring white blossoms each year. This year two neighboring plants have a few white blossoms of their own. It seems 4 or 5 stems each of the three plants are now beautifully white.
I am silly with excitement at this. I know I could buy white spiderwort and be done but this is so much more fun. How do I encourage more white? Should I separate the purple and white, or leave nature alone. Any advice appreciated. Thank you.
