[YvonneH]

Hello everyone!
I'm new to computers and the internet but I love plants and love to garden so my son is handleing the computer so I can participate. This is the only one of this flower/plant growing in our San Fransico Bay area garden in California. Can someone tell me what this flower is?

Sincerely,

An Amatuer Garderer

I did a post in another forum at gardenweb.com and this was the reply.

I'm pretty sure that's Asiatic Dayflower. It's very invasive here in GA - one plant comes up, and the next thing you know it's everywhere in the area. When you try to pull it, if you leave even one little piece of root it will come back out. And when you pull it out, the plants have to be left in the sun to bake for a while or tied up tightly in a trash bag before you throw them out, because otherwise they'll revive in the dumpster or compost pile and come back out. I don't know how bad it is in CA, but whenever I see it starting here I dig it up and make sure it's dead

I'm going to follow up on the lead but would still appreciate any help. Thanks again for your interest and posting in this topic thread!
