its been years since I visited mr kim's nursery. back in the day, and perhaps still today, mr kim had the best selection ( and prices ) of procumbens nana junipers I'd ever run across-anywhere. he also had many large prostratas. some of the best junipers I have, came from him
Sadly the SD card on my phone was nearly full so I only got five pictures from Mr. Kim's place today. The first two are elms which would totally work for shohin. See my sunglasses for scale in the first pic:
Pine about caliper about as big as my thigh (mind you I have chicken legs) and a couple of junis.
