I reached out to the Houston Arboretum describing my project and my need for native plants. They responded immediately. They are steadily cutting plants out and I made a big haul today. My studio floor is covered in drying plants. I am drying these on my patio. Curtis suggested every morning I flip them, so rodents don't decide to nest in them. I love all animals but I am not a fan of rodents nesting around my house. They offered me to raid their compost bend as I need. :)
