I love how the hollyhocks pick up the light on a cloudy day. Yes, I know it's due to the UV rays which cause the pigments to flouresce but who cares about the technical reasons. Family Malvaceae, Genus Alcea
I did not have the heart to pull this weed out. I don't know what it except it is likely a Mallow in the family Malvaceae.
Likewise, the squash flowers luminesce as well. To be honest, these were volunteers. I understand that this is risky as seeds do not run true. I believe these are likely to be Japanese squash, kabocha.
So unusual to get rain in the summer in southern California.
