Answer: Chrysogonum virginianum is a wildflower that blooms in early spring, so it may be that the retail process and transplanting process caused them to bloom lightly this year. As they settle in and mature, I would expect them to bloom more heavily. Having said that, they are not terribly heavy bloomers being more on the subtle end of the spectrum even at their best as is typical of the charm of so many of our wildflowers. It always seems like the few weeks of annual bloom period is just too short because they are so pretty. Here is a photo of what you might expect
In the meantime, make sure the soil is evenly moist but not sopping wet, maintain several inches of organic mulch to help feed the soil over time, and take care not to overfertilize since too much is not better than too little. An annual application of an all purpose complete granular fertilizer such as 10-10-10 in early spring (read and follow label instructions) and/or some compost in late fall or early spring should be sufficient.
