Monet Moment Cardinal Flower. The next crop of this selection will be ready September 15, 2018.This exquisite Cardinal flower was developed all thanks to master lobelia breeder Thurman Maness of Pittsboro, NC. This selection produces a 3' spike of bright pink flowers in August and September which is a hummingbird magnet. This species prefers mildly moist soil but good drainage, particularly during the winter. Don't allow organic debris such as leaves and stems to cover its crowns during the winter.
