How can I arrange the flora around me?

I’ve been a florist for many years and the floral industry, like most industries, relies on a global supply chain. I’m an avid observer of all things, including plants, and there are a lot of beautiful ones here in California. I got curious about making arrangements using only what I could gather from my environ. Partly as an experiment in extricating arrangements from the global flower market, partly as a way of showcasing the seasonal flora of the region, and most of all as a challenge for myself to make beautiful arrangements with limited ingredients, sometimes without flowers at all.
