These are both great yuccas. I was able to order 'Banana Split' on eBay last year, but it was really hard to find. I ended up ordering internationally. It looked pretty sad when it arrived due to the long shipment. 'Margaritaville' now goes by the name 'Margarita.' I found it locally a couple of years ago at a higher end nursery. I looked for it again this year and was told that they probably wouldn't be getting any this year. I have seen it for mailorder from Cistus Nursery for a small size plant. Hope this helps.
