Three years, we planted a Cardiocrinum. These plants tend to be monocarpic, dying after flowering. This one spent two years as a little knee high plant.
On the third year it shot up to 5 feet. Every day, we watched as the large flower heads formed and, as they were ready to burst……
We went away for a bicycle trip to Germany.
We left instructions with the young son to photograph it if it bloomed while were were away.
Here is what he saw.

The night we came back, there was one wilted flower hanging on.
And it dropped off the next morning.
Three years!
