Looks similar to Sanicula, such as Sanicula canadensis.

I found, a long time ago, that "weed" seeds are so fine that the tines of a rake not only do not move them but more often then not will cover them with soil so they germinate better. Backin those days when I did till I would till the soil, wait a week and till again to kill any "weed" seeds that did germinate (watering if necesary), and maybe doing that again. What you do depends on what use this area is to be put to. If a garden you may well be able to lay down a good mulch (maybe newspaper or cardboard first) and plant. If a lawn maybe till twice, or more a week or more apart before laying sod or maybe seeding. Seeding turf grass might be best done in early fall when it is cooler and, usually, wetter.

The debated species is A. curassavica or Tropical Milkweed which is the popular species in Florida and much of the southern states because it does so well and comes back from roots each spring. Some say that it is causing the Monarchs to stick around longer than they should, but some say that once the Monarchs undergo the hormonal change that allows them to migrate and live so long in Mexico, then that is where they will head, regardless of what's in bloom. They will just have more sources to fuel up on the way south, but only in the southern states. The midwest is another story, where much of the areas monarchs might stop to refuel have been replaced by crop fields. I have read that some farmers in the midwest are starting to allow for 'wild borders' around the crops, but time will tell if this will be a boon or just not quite enough. Some Monarchs in South Florida never go through the hormonal change required to migrate and will instead stay. Some even say that South Florida is actually a natural stopping spot for migrating Monarchs from the Eastern US, it's just not as well known as the Mexican migrations. But those in South Florida not only survive the mild winters, they continue to breed and this leads researchers to think that maybe there just isn't enough genetic diversity left among those populations to ensure stronger offspring. And with all the development of suburban/retirement communities in Florida, we're quickly becoming a nectar/milkweed barren place as well. This is another case where lots of fingers are being pointed at one sure reason for the population decline, when the more likely truth is that there are a number of reasons causing them to disappear. Personally, I think the populations of Monarchs in Australia are proof that the species is able to adapt to climate and location, leading me to believe it is the many sterile yards and urban areas that deserve much of the blame. There are even many beautiful, plant filled gardens down here in Florida that are really little more than deserts to butterflies.
