>>798816Are you having it in a very wet place where the soil drains really bad?
It doesn't like it too wet. That being said, my November T. vulgaris seedlings (like 15 or so total) are all growing like crazy and flowering all over the place (not uncommon to see 5 or 6 bees on a single shrub at a time), even though we have heavy clay soil and very rainy weather so far
