Water Hemlock

You are correct ForestDragon, I got confirmation from the Orlando Wetlands themselves....thanks again

I wouldn't rule out the hemlock. It is a water loving plant. Wild carrot prefers dry fields and waste places.

Do you have closer views of the leaves, stems and blooms of this plant or full image of the whole plant? It looks quite large for wild carrot and I think the blooms look slightly different shaped.

Wild carrot has delicate, fern-like leaves that smell like carrot when crushed. https://plants.usda.gov/java/largeImage?...

Here is a plant I found (Cicuta maculata): http://www.projectnoah.org/spottings/122...

This was found growing in a local park, right by the water. It was a very tall plant. Note how the plant branches.

Take a look and see what you think.

Thanks Hayley for suggestions, I went with Queen Anne's Lace as it looks most like it and as these were intentionally planted in a wetlands I assume theat the hemlock's are out as they would hurt the animals

Also Angelica and lovage have a similar look. Too narrow it down, you could use a key to the genera of the carrot family and think about details you can remember -- was the plant hairy? Were the stems hollow? Etc.

There are a lot of plants that look like this, hmm... Queen Anne's lace, cow parsnip, poison hemlock, water hemlock?
