Both look like Cycas revoluta, just different characteristics.

been awhile since I seen some that big that wasnt at a nursery..nice sagos

Thank you Eric and Mike. :)

have you had any make seed yet? my friend has 2 large ones, male and female which make seed but everyone I try won't germinate

Alex, the trick to keeping them from flushing in the off season is keeping them almost cold. Inside the house, I have been much less successful with them.

No I haven't had them seed. I have had one for many years and acquired the other this fall. I really like them but they are hard to move around and take up lot of room in the greenhouse, but worth the pain I guess. :)
On another note when I first got interested in palms I had a small sago that I stuck under the house in the crawl space one winter because I ran out of places to put plants. I thought oh well if it lives fine if it dies fine. Come spring I pulled it out and it looked exactly the same as the day I put it under the house. Not that I still do that but that's another option to keep them from flushing. :)

Depends on the winter, obviously. Last winter and this winter (so far), would be fine for them in the ground here--especially as both winters have been fairly dry and very mild. I believe this species is hardy to 8--which you might have in zone 7 (next to the house--or under it!).
