I planted my tulip bulbs last October (Minnesota) and they have grown to about 12-14″ so far this spring. However, there is not sign of a stem, just leaves. What causes this and will the stems still be growing. My neighbors all have blooming tulips at this point.
Sometimes bulbs are sold, often more cheaply, when they are still too small to bloom. Disappointing! The leaves are building up the bulb and it will probably bloom next year.
