Your false indigo may have great foliage but no flowers due to factors such as insufficient sunlight, improper watering, or nutrient imbalances. False indigo plants typically require full sun to thrive and produce blooms; if they are in too much shade, they may focus energy on foliage instead. Additionally, over-fertilizing, particularly with nitrogen, can promote leaf growth at the expense of flowers. Lastly, the plant's age or a lack of maturity might also influence its flowering capability.
