Well over thirty five years ago Harlan Hamernik and I visited with a long time perennial grower in Lincoln, Nebraska and for some reason he got on to the subject of how lavender flowers were totally mislabeled as blue in the horticulture field.
The older gentleman then went on to call this process taking the liberty of “Nurseryman’s Blues.”
In other words the nursery industry was desperate for true blue flowers and with the Speedwells you will discover that the ones listed as blue are truly just that – BLUE.
