safari zone
You'll find a lot of them nothwest of ecruteak city
You can catch and exeggcute in the safari zone, in pretty much every zone. I would go for any lv. 25 that appears. Assuming that you want an Exeggutor, buy a Leaf Stone from the Celadon Dept. Store for 2100 Poke. Use it on Exeggute, and hey presto, there is your exeggutor. Hope this helps.
You can find Exeggcute in the Great Marsh.
Exeggcute evolves into Exeggutor using a leaf stone.

You can't catch Exeggcute on Pokemon Sapphire. You need to trade one from Fire Red or Leaf Green.

To catch an Exeggcute, you have to headbutt trees in places like Ilex forest or trees by the roadside. you can get headbutt (TM02) from a guy in Ilex or you can buy it from Goldenrod Department store for $2000. I hope it's useful. :)
after you get the national dex it appears in the great marsh safari zone
you cant catch an executor, but if you get an exeggcute from the great marsh and level it up, you can use a leaf stone on it to get it to evolve into an executor

exeggcute > leaf stone > exeggutor
Gloom, Exeggcute, Weepinbell, and actually I think that's it since you can't catch Nuzleaf (or can you?).
