How to tell the difference between Pampas grass and Jubata grass?
Pampas grass and jubata grass can be differentiated by general habit, leaf shape and color, and flowering time. Here on the California coast jubata grass blooms first, beginning in late July and continuing into September, while pampas grass blooms from late August but mostly in September. Immature flowering plumes are generally deep rosy lavender in jubata grass and silvery white or pale violet in pampas grass. Leaves of pampas grass are somewhat more slender and rise in an arc to the height of the inflorescence, while jubata grass has leaves that are slightly wider, and usually one to three feet below the inflorescence. Female inflorescences of pampas grass may have a few male flowers at the base; jubata grass has only female flowers. Other minor differences could be noted, but because of variability among plants, these are not always helpful.

Is Jubata grass a forestry?
In north coastal areas where forestry is dominant jubata grass at first was welcomed. Its harsh, cutting leaves ( cortaderia, from an Argentinian word, has the same root as the Spanish cortar, to cut) kept deer out of reforested areas and protected tree seedlings from being browsed. Later, however, the grass itself crowded out the young seedlings. In the 1960s Georgia Pacific had to abandon 1,100 acres in California’s Humboldt County to jubata grass as there was no economical way to control it. At that time 7,000 additional acres were severely infested.
Why is pampa grass dangerous?
Pampas grass increases its density and colonizes semi-natural areas in a short period of time , being a threat to native plant diversity. Due to low decomposition rates of standing dead leaves and senescing panicles, it increases fire risk. The sharp leaves can produce superficial cuts and flowers may provoke allergies in summer.

Where did panicles originate?
The panicles were grown and marketed in the area near Santa Barbara. It was first recognized as naturalized in California in 1929 when a specimen was collected near Los Angeles. Herbarium records indicate that it has expanded since then at approximately 218 km 2 per year. Currently, it is present in at least 19 Californian counties, where it has colonized relatively undisturbed native plant communities ( Lambrinos, 2001 ). Generic analysis of invasive plants indicates that the expansion originated from multiple cultivated gene pools as well as landscape plantings ( Okada et al., 2007 ).
How many seeds can a hermaphrodite plant produce?
A panicle from a female plant can produce more than 50,000 seeds; whereas seed production in hermaphrodite plants is one order of magnitude lower ( Domènech, 2005 ).

Seed viability between the two sexes is also different; it is five times greater in seeds from female plants than from hermaphrodites.
