Ricinus communis flower

It's a common weed tree. It can grow much larger and wider. It pops up in asphalt along the freeways and so many other areas here in California.

Yes, weed seen everywhere...in every little crevasse .
The cultivated ones are pretty though.

Yes, when trimmed and watered it can become large and very nice.

Here's a photo so an old tree (relatively speaking probably 8 or 9 years old) in Balboa Park.

Thank you. Looks attractive like that.

They grow to that size in England too, but of course they're bought & planted in our gdns. I Used to have to prune one sometimes in a friends gdn, to contain the size. It kept it nice & bushy, with nice new growth.

I have never seen it cultivated Feverfew. Only in the wild.
