Pre-treatment: None required
Establishment: Seeds are fairly slow to collect as plants are thinly scattered in native stands. In most collection years, moderate to heavy insect predation is apparent. X-ray examination of test lots showed up to 17% of seed was empty, and others showed signs of insect damage.
