"OP" vs "OP"

By RickCorey
December 7, 2013

"OP" means "Open Pollinated", but that term is used in two different ways. It can mean an inbred OP variety that can produce seeds that come true to its parents. Or it can mean that a specific batch or packet of seeds labeled "OP" was "openly pollinated by wind, insects or birds," without saying whether other varieties might have cross-pollinated it.

Thank you very much for the thumbs, guys!

*Blush*

As soon as i saw it in print, I thought "how could I not have mentioned Joseph's landrace strategy?"

So I submitted an edit right back to Trish. Sorry to make more work for you, Trish!

I like Joseph's landraces - both the concept and the delicious results I've gotten when I trade seeds with him. But I also like another term he uses: "promiscuously pollinated". It helps clear up a lot of the OP vs. OP confusion, and describes well the practice that many small-scale gardeners have of collecting seeds. I see it this way: let pollination happen in whatever way it will (insect, wind, etc.) and collect whatever seeds result.

In my small garden, I would often grow a small number of plants in total, but as many varieties as possible, and never had the space for proper isolation, so any seeds I saved ran the risk of being mutts (hybrids of undefined parentage). I appreciated the genetic diversity and avoided growing F1 hybrids in any case, so it wasn't a problem, but obviously this strategy is not for everyone.

PS: great article, Rick! Thanks for posting this useful information. I got so caught up in my excitement over pollination that I forgot my manners *Blush*

OP in Australia. In reference to liliums , OP is short for Orienpet, whereas, in America, the initials OT are used
lily freaks are not geeks!

Thanks very much!

>> But I also like another term he uses: "promiscuously pollinated".

I agree, and I wish everyone would use "PP" instead of "OP" when they trade seeds that were pollinated with a lot of genetic variety.

Probably more home gardeners have "promiscuous pollination" among multiple varieties than have isolation distances.

I think it was Deb who pointed out another abbreviation, useful when you want to say that you collected this seed FROM the variety 'Gorgeous Rarity' , but the pollen was "whatever".

ex 'Gorgeous Rarity'.
