These Puya Mirabilis seeds were sown, using my dome method, several weeks ago.
They were leftovers from late spring 2011, and sat in the hot garage last summer, until I located them.
The germination rate appears to be about 25%, and could climb higher over time.
All things considered, this is quite admirable, and demonstrates how well Puyas have adapted to the harsh conditions of the Andes.
UPDATE:
ReplyDeleteEven though some of the seeds germinated, they are not surviving as well as fresher seed. Apparently old seed lacks something that sustains them after germination.
