They are mostly grown from seeds:
"Delonix regia. Royal Poinciana. This spectacular tropical flowering tree is propagated by seed. Germination is rapid when seeds are treated to soften seed coats, as by pouring boiling water over seeds or by soaking in concentrated sulfuric acid for 1 hour."
But this paper below proves it is possible to grow them from hardwood cuttings, with proper care:
