Eryngium yuccifolium (Rattlesnake Master) [25 Seeds]
Germination Information: I recommend these seeds only for gardeners who are experienced with seeds that benefit from or require a chilling period.
The easiest approach is to sow the seeds, barely covered, in fall to early winter, setting the pot outdoors in a spot protected from mice and slugs so they can get a chilling period and then germinate when conditions are right in spring.
If you sow after January, give the pot an artificial chilling period of about 2 months.
It is possible that these seeds could germinate (though perhaps at a lower than optimal percentage) if you sow them in warm, moist, bright conditions. But if you try that and no seedlings appear within a month or so, then try the 2-month artificial chilling period.
Note that this information will not appear on the seed packet you receive.

Rattlesnake master (Eryngium yuccifolium) is a distinctive perennial with spiky grayish green leaves on 4- to 5-foot-tall stems that are topped with ball-shaped clusters of white flowers in mid- to late summer. The mature seedheads last well into winter, creating intriguing natural sculptures when coated with ice or dusted with snow. This U.S. native is a memorable sight in meadows or naturalistic plantings and is a valuable source of nectar and pollen for a variety of bees, wasps, butterflies, and other pollinators. It looks terrific in arrangements too, so consider growing some in a cutting garden. (Be prepared to provide some sort of support there, as the plants tend to sprawl if grown in good soil without root competition from nearby partners.) Full sun. Zones 3 to 8.
Collected in mid to late September 2022. At least 25 seeds. Unknown ecotype.
