Propagation of 4 Florida coastal dune species.


Softwood cuttings of Florida coastal dune species gulf bluestem (Schizachyrium maritimum Chapman (Nash) [Poaceae]), seacoast marshelder (Iva imbricata Walter [Asteraceae ]), false rosemary (Conradina canescens Gray [Lamiaceae], and Atlantic St Johnswort (Hypericum reductum (Svens.) P. Adams [Clusiaceae]) were propagated with the aid of commercial rooting hormones containing indole-3-butyric acid (IBA) and  -naphthaleneacetic acid (NAA). For all 4 species, an external application of an auxin was not essential for rooting. However, auxin application did improve root quality for seacoast marshelder, false rosemary, and Atlantic St Johnswort.
