Cultivation Details

Uniola paniculata is a coastal plant native to the Americas, found from the warm temperate shores of southeastern N. America to the tropcal shores of Panama and the Caribbean. It can be grown away from the coast in mild winter areas and, especially in provenances obtained from the north of its range, is known to be able to withstand occasional, short-lived temperatures falling to about -7°c. It is found in areas where the mean annual rainfall can be within the range 680 - 1,520mm[

Sea oats thrives, and is actually stimulated, where sand is actively accumulating - the accumulation of sand stimulates the roots into more vigorous growth thus ensuring the plant spreads more rapidly. It is highly tolerant of xeric conditions, but does not tolerate water logging of the roots, which will stress or kill plants within a few days[

Agroforestry Uses:

The plant is exceptionally tolerant of the harsh conditions associated with coastal beach environments, such as:- salt spray; short inundation of saltwater from storm surges; strong winds; xeric soil conditions; and rapid sand accretion. With its tought, spreading root system, it is considered an excellent pioneering species along the coast, establishing rapidly and colonizing the fore-dunes and dune crests. It is also a climax species due to its ability to stabilize the dunes and to persist in these extreme coastal beach conditions[

Propagation

Seed - sow early spring in a nursery seedbed and only just cover the seed. Seeds from the north of the plant's range benefit from being kept in moist sand at around 4°c for thirty days prior to sowing, whilst seeds from the south of the plant's range not only do not require a cold treatment but their germination is impaired by it[
