Pinellia Polly Spout

From: "Tony Avent" <tony at plantdelights.com> on 2010.07.07 at 15:41:07(21161) Dear Aroiders: I wrote last year that the "sterile" Pinellia 'Polly Spout' had indeed become fertile when it was grown near another flowering species of pinellia. We planted our first batch of seed from P. 'Polly Spout'x P. tripartita last year and they are now flowering. I had expected a range of variation, but instead got what appears to be a case of obligate apomixis, as every seedling appears clonal. We have established another isolation block with P. 'Polly Spout' and P. cordata and P. peltata. I will report on those seedlings next season.

We planted an isolation block of P. 'Polly Spout' and P. cordata. By the end of last summer, all of the dozen seedlings from P. 'Polly Spout' flowered and appeared clonal, with no sign of P. cordata. This spring they have re-emerged and indeed still appear clonal. We had assumed last summer that they were in fact clones of P. 'Polly Spout', so we planted them in a row beside P. 'Polly Spout' to be sure. Now that they are in flower, they are identical to the original clone except for their size, which is uniformly 50% large than the parent...quite unexpected. There is no difference in growing conditions.

I wrote about it here. http://plantgasm.com/archives/4167 It's written for a general audience. Please do let me know if I got anything wrong. Which Pinellia should I get next?

Are these larger Polly sterile, also? I suppose it is possible that the introduction of pollen from P. cordata influenced chromosome replication somewhere along the line and these larger "hybrids" may be triploid or tetraploid. If the latter they might have increased fertility. And it will be interesting to see if Polly and the new larger Polly that are now growing together can cross breed. Is a fertile 'Super Polly' in the future.? Derek if you are in the market for smaller Pinellia I can recommend both P. cordata and P. peltatum. Both very attractive smaller less aggressive species.

From: Tony Avent <Tony at plantdelights.com> on 2011.04.21 at 21:58:40(22040) Jim: Last near the new cross was indeed fertile, but then we have it in a row beside P. 'Polly Spout'. To really find if it is also self sterile, we would need to move a plant into an isolation block, which we have not done. We grew additional seedlings from the new cross, and they, like their parents appear to be identical, although they aren't old enough for a size comparison yet. It was my hope to have some characteristics of P. cordata in the hybrid, but no luck so far. I also added P. peltata to the isolation block with the original P. 'Polly Spout' in hope of hybrids that have characteristics of both parents. Stay tuned.
