A neighbor is a professor at MCC.. She had her class do them as a project.. Then she handed them out to those of us that would plant them.. If you look in the photo with the plaques, there is a wine bottle.. After I water the potted plants's, fill up the wind bottle and turn upside down..Looks like we'll cool down yet before climbing back up that ladder. I hope they are right. Yesterday was yuck. Where do you get milkweed seeds? I don't think I've seen those. I just got done giving my garden a really good soak down to hopefully keep it going through today
