Euphorbia obesa with male and female flowers?

Post by splitchestnut »

My oldest euphorbia obesa which had always produced female flowers suddenly surprised me by producing female AND male flowers at the same time. Is this common for obesas? I hope it's not a sign of stress or other issues.

Age and desperation? Has she ever produced seeds?

There are some species where this will happen.

I got her in 2017, I'm not sure how old she was when I got her. She's never made seeds since I didn't have a male obesa until recently and even now they aren't always blooming at exactly the same time that pollination would be possible. I also wasn't particularly interested in making seeds since I don't really have room to grow more plants but if it's important for her health I can definitely make it happen!

I have one relatively young obesa that I tagged as male, since it produced male flowers. However more recently it is producing female flowers. No sure what is going on.

Interesting. Some fishspecies can change the sex too, if the male fish in a ‘harem’ dies. The links discuss this fenomen in plants and fives some clues to why this happens.

I have noticed before that Euphorbia bupleurifolia has changed sex. I don't know if this happens often (probably not) but there have been reports of this happening before.

See also viewtopic.php?f=23&t=43165&p=361976&hil ... ex#p361973 for another report of this, next to mine.
