Letting the water drip is more effective because it gives the roots a chance to get as much water as possible. I dont think the difference would be too noticeable, but it does probably help save on water -Alex

Yes thats a coconut palm. I really nice one too. So lucky! I've never seen one for sale that size here. As for variety Idk. Its hard to say. I think the only real way to know is if you can get it to fruit... -US_Marine

Rate of growth is one factor to consider but also consider how robust the plant is--especially growing OUT of their natural hardiness zone in the North. Don't have too much experience with palms from seeds other than with Washys and Date palms. Have had great success with Canary from seed--less so with the "True Date". You might want to try Butias from seed. They are fast grower, cheap, common, cold-hardy and vigorous! Also, keep in mind the importance of providing tropical heat to hasten germination--it makes all the difference in the world even fir the more cold hardies.
