Title: Mystery self-sower
Post by: johnw on June 23, 2015, 05:06:48 PM: These have been self-sowing in our pots. I have narrowed it down to 2 possible culprits but would like to hear what others thinks. They are not being tossed!

Post by: Lesley Cox on June 24, 2015, 05:13:22 AM: The answer then, is obviously to let it self sow. I have a single seedling germinated some months ago but died down now. Hoping the coming (when?) spring may show a few more. -12C this morning after -11 yesterday. We just don't get these kinds of temps so looks like this winter is one of the tough ones. Generally I feel hard-done-by when we dip to -5. It's that currently in my bedroom now, where I'm typing this post!

Post by: gote on July 03, 2015, 01:36:10 PM: It looks more like Jeffersonia (also called Pl*****a :() Ranzania usually has smoother edges to the leaf. Ranzania leaves are divided more or less like an Aquilegia whereas Jeffersonia has single leaves on a stalk. I hope I am right. It is too hot today for me to go out and have a look.

PS
Ranzania seeds should be sown immediately from the berry. They should be kept outside all the winter. They will then germinate in the spring. Seed exchange procedure usually kills the seed efficiently.

Post by: Lori S. on July 03, 2015, 04:08:48 PM: I don't think they are Jeffersonia, not Jeffersonia dubia at least, of which I have lots of seedlings (and I doubt J. diphylla also). The J. dubia seedling leaves are almost round, very regular around the edges (not rippled as shown), and not prominently veined (as shown).
Here's a photo of young seedlings (one has been nibbled by something) - can get a photo of older ones if it would help.

Post by: johnw on July 04, 2015, 02:42:53 AM: Thanks Lori. Thinking back it can only be Ranzania given where the nurse pot was situated. We suspected that but still can't belive it!
