So I haven't had much time to play with those Miyasama Trident I bought. Actually I planned on number of things, that ended up not working out. I planted one on the ground and kept one in a pot over a small rock (my kid found it during our FL vacation). Rock is not large enough, but I figured what the heck.
Honestly, I haven't kept them in the best of condition they deserve. I am surrounded by clay soil and poor watering condition, so they didn't grow as thick as one would hope. At any rather, each season, they shoot out quite a bit of growth that I had to trim closer to Spring.
Anyway, this is how they look today
