Those sunflowers are huge compared to mine. I don't even know what kind of sunflowers mine are. I planted some seeds last year, but the sunflowers didn't do well. Then later more sunflowers popped up around the yard, I think seeds from my neighbor's yard. She had a ton of sunflowers. Now that they have moved out, it looks like the owner is totally changing the garden. I saw a lot of landscape fabric and mulch. Also a much shorter wall along the front of their house. I don't think that is a good idea - not enough wall to keep the mud off the sidewalk. I'm waiting to see if he will get rid of all the sunflowers - a shame they don't transplant well.
