Flowering Trees Carried by Cross Creek Garden Center Richmond. We have available year round many of the tree varieties listed below. Most are sold in 15 gallon containers, and we also have many in 3 gallon, 7 gallon and large ball & burlap (field dug) sizes. Other than the Magnolias, deciduous flowering trees can be planted all 12 months in Richmond & central Virginia. In the first year (establishment year), the trees will need water every week without rainfall, and increased water from May-September. All flowering trees require several hours of sunlight for best show of color. Once your tree(s) are tagged at the Nursery, we offer Delivery (drop off) and a planting service.
