Hey Chris, and welcome. I have a basjoo that's been in the ground here for two summers, probably a year old pup when I bought it. This summer, it produced 3 pups, the largest being about 10 inches tall. Depending upon the actual age of your basjoo, I'm thinking it could be too young, but I'd be more inclined to think it may be due to small pot size. I'm assuming you bring the plant in for the winter, but I think if you transplant into a larger pot with enriched soil in the spring, you'll see those pups you are looking for. Mine was showing a small pup when I pulled back the mulch this past spring, and two more were produced this summer. I'll wait until they're a bit bigger next summer before removing them though. Hope this helps a bit.
