Question about leaf patterns

Hi Permies,

Many Moons ago I think I heard Geoff Lawton on a podcast say something about how we can use leaf patterns to recognize dynamic accumulators. I live near Vegas (Zone 9a), and I’m looking to start a permaculture project in my backyard.  I saw plant and I thought Geoff mentioned a plant that has this kind of leaf patterns might be a nitrogen fixer. The plant is a Red Bird of Paradise (Caesalpinia pulcherrima).  Does anyone out there know where I can look up info on finding these kind of patterns?  I don’t know if it is or isn’t I’d jut like to know how to find the info!

Thanks

Maybe compare known nutrient accumulators?
Definitely looks leguminous to me.
