The first two pics are the same plant. I thought I sowed squash but then realized it's not. The second plant wasn't planted by me, was hoping to see flowers but it didn't bloom and now starts to wither. The third I'm not sure it's veg, flow or weed. Probably not planted by me. It's right next to one of my tomatoes…on the left…wonder if I should take them out. Thanks.
I took a picture of the root. It's reddish but no bulb. I seems starting from a spot nearby and came out where I sowed squash. It's a little over one foot, isn't it too tall for radish, and the flowers too good?
I think it is a Radish. Very often those Radish plants that are unable to develop a bulb will quickly go into bolting and flowering (or may be it is the opposite: those that go early into bolting can't develop a bulb). And, no, it is not too tall, far from that. To be sure wait for the seed pods to develop radish seed pods - Bing images They should taste exactly like radish bulbs.
