Seedling trees normally take longer to flower than those produced from grafting or rooted cuttings. The reason is that perennials from seed usually require a juvenile phase prior to flowering, which may last for a few months for some herbaceous plants to well over 15-20 years for some woody plants such as certain nut species. When cuttings are rooted or graft wood is taken from mature trees and grafted onto seedling rootstock, the new plant does not experience juvenility, since the propagation material was from a mature source. We are not sure what the juvenility period is for dogwood, but 5 years or longer would not be uncommon. So our advice would be to be patient for a while longer.
