In dense swards Lee plants grow more erect but maintain stronger basal branching and do not grow as tall as Glenn. Perennating plants flower and produce seed in spring-early summer when moisture is available. Agronomic characters Lee is predominantly perennial, Glenn annual. The percentage of plants that perennate depends on the length of dry season, frost, and grazing pressure. Seed yield potential, though high, is lower than for Glenn.
Ripe seed holds well on the standing crop and is readily direct-headed.
Southedge Seeds, Mareeba, has exclusive seed production rights to the variety under licence. It produces adventitious roots from stems touching moist soil and is very suited to low-lying, waterlogged soils. Glenn and Lee will also grow in clay soils receiving sufficient moisture. Good liveweight gains in steers have been recorded from Lee pastures at 'Tedlands' south of Mackay. Lee is less affected by powdery mildew than Glenn, but seed crops may require treatment with a fungicide.
