Vanilla Strawberry did not bloom
I bought Vanilla Strawberry Hydrangea from Jung Catalog this year. I bought 4 plants. 3 were gifts and 1 was for me. Out of all the plants 1 bloomed and it is gorgeous, 1 did not take well and is still struggling, but 2 others took well and grew nicely. My plant and the other one that did well more then double in height and width, but did not bloom. Should I be worried? Do you think there is something wrong with the plants or is it to be expected?
