Parthenium integrifolium (Wild Quinine) [20 Seeds]

Germination Information: I recommend these seeds for experienced seed-starters only, because they may require some patience. The easiest approach is to sow the seeds (just barely covered with growing medium) in fall to mid winter, setting them outdoors in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring.

If you sow after January, set the pot in a plastic bag in your refrigerator for about 2 months before moving it to a warm, bright place for germination. (Remove the bag if the pot will be exposed to any direct sun.)
