So I found this cool website that shows tree species by height, girth and age in the US, as well as the world.
http://www.monumentaltrees.com/en/heightrecords/usa/
So here are the results if you only look at the tallest species per state.
1. CA: Sequoia sempervirens (Coast redwood) | 115.72 m (379.66 ft)
2. OR: Pseudotsuga menziesii (Coast Douglas-fir) | 99.76 m (327.30 ft)
3. WA: Pseudotsuga menziesii (Coast Douglas-fir) | 69.80 m (229.00 ft)
4. MD: Liriodendron tulipifera (Tulip tree) | 42.67 m (140.00 ft)
5. NC: Metasequoia glyptostroboides (Dawn redwood) | 39.65 m (130.09 ft)
6. LA: Pinus taeda (Loblolly pine) | 37 m (121.39 ft)
7. NJ: Liriodendron tulipifera (Tulip tree) | 36.57 m (120.00 ft)
8. FL: Pinus taeda (Loblolly pine) | 34 m (111.55 ft)
9. PA: Populus deltoides (Eastern cottonwood) | 32.52 m (106.69 ft)
10. KY: Metasequoia glyptostroboides (Dawn redwood) | 27.40 m (89.90 ft)
11. UT: Populus fremontii (Fremont cottonwood) | 25.40 m (83.33 ft)
12. CO: Populus fremontii (Fremont cottonwood) | 22.60 m (74.15 ft)
That database only shows about the tallest 3 specimens per species so it is likely that there are many other states that would be fairly high up the list, just that their tallest tree isn't one of the tallest for that species, but if you know what the tallest tree is in your state let me know.
here are the results of the trees based on girth
1. CA: Sequoiadendron giganteum (Giant sequoia) | ~29.10 m (~95.47 ft)
2. WA: Thuja plicata (Western redcedar) | 18.80 m (61.68 ft)
3. FL: Taxodium distichum (Bald cypress) | 14.15 m (46.42 ft)
4. OR: Chamaecyparis lawsoniana (Lawson's cypress) | 11.46 m (37.60 ft)
5. LA: Quercus virginiana (Southern live oak) | 9.17 m (30.09 ft)
6. NY: Quercus alba (White oak) | ~9.01 m (~29.60 ft)
7. VA: Quercus pagoda (Cherrybark oak) | 8.32 m (27.30 ft)
8. NJ: Platanus occidentalis (American sycamore) | 8.05 m (26.41 ft)
9. UT: Populus fremontii (Fremont cottonwood) | 7.74 m (25.39 ft)
10. PA: Platanus occidentalis (American sycamore) | ~7.62 m (~25 ft)
11. AZ: Populus fremontii (Fremont cottonwood) | 7.55 m (24.77 ft)
12. OH: Quercus alba (White oak) | 7.32 m (24.02 ft)
13. WV: Quercus macrocarpa (Bur oak) | 6.76 m (22.18 ft)
14. MD: Liriodendron tulipifera (Tulip tree) | 6.40 m (21.00 ft)
15. IN: Platanus × hispanica (London plane) | >5.75 m (>18.86 ft)
16. MI: Juglans nigra (Eastern black walnut) | >5.20 m (>17.06 ft)
17. NC: Metasequoia glyptostroboides (Dawn redwood) | 3.99 m (13.09 ft)
18. KY: Metasequoia glyptostroboides (Dawn redwood) | 2.43 m (7.97 ft)
Same scenario applies as for height.
So any surprises? I personally was somewhat surprised to see only 9 states that had trees taller than 100 ft. And apparently many of the trees around my neighborhood would be among the tallest in the nation since many of them are >70 ft.
