V. hastata can be short lived, but it seems unlikely every plant would have died of old age in the same year. Was there an unusual climatic change such as being extra dry, extra cold or a late cold spell? Did you add compost or other fertilizer from an outside source? I have purchased previously reliable potting soil that stunted and even killed my plants before I figured it was the common factor. All I can advise is to look for seedlings over the growing season, and husband any you find.

Thank you for responding to my question. You may not have noted, it's 2 years old. The seedlings did appear, just later than I expected. I am accepting, now, that V. hastata in my landscape will be predictable in its return every year, but unpredictable in its specific location. It continues to be one of my favorite participants!

Oops, I was looking at Unanswered questions, and did not notice the date. I'm glad the plant returned. I have also noted that native plants don't always stay where you put them. I planted Pitcher Sage (Salvia azurea) one fall and it didn't come up until the second winter, then only lasted about 3 years.

BTW, thanks for seeking out the unanswered questions. I've been around long enough to know the good people on this sight 1) may not know the answer, 2) may miss the question, 3) lead busy lives. But some who get no response may get their feelings hurt. Your approach helps.
