Is Helleborus foetidus short lived?
I purchased three small Helleborus foetidus about 5 years ago. They grew up, flowered a couple of times, always looked great until last season when they all declined. One seems gone completely, the other two are shadows of their former selves. We did have a drought last summer enough to make my astilbes suffer some but their still alive - I think. I did water.
I am not worried because they have selfsown very freely. Just wondering.
