I've seen the heirloom here before but I think its seasonal. I would check Hong Kong Market on 11205 Bellaire first. Might be closer to u
They have over 30 squash types it's all based on the seasons, supply and demand, think of it like the swap meet or flea market of fruits, veggies, treats, cultural decorations, honey, nuts, and endless many goodies for the entire Htown
It would be a good chance they have it patty pan squash they had stuffs I've never seen before.
