Wildflower of south-central United States. The only annual eryngo we've tried thus far, this looks to be a stunner with its purple flowers; a departure from the greenish-white to steely-blue spectrum of the perennial species we grow.
Through the middle of summer, the plants grew large and bushy, and somewhat floppy, with lots of green flowers-in-waiting. Then in mid-August, some of the bracts turned purple. By late August, many flowers were purple from head to toe. Finally, toward mid-September, the real deep purple arrived. All in all, quite a plant! I hope it sets viable seeds...

|Edward in the Netherlands||Mar 10, 2009||hallo ! So curious how to grow Eryngium leavenworthii. tried to find detailed information about soil preferences on your site. for example acidity tolerance. Ph preference.
I am located on poor sandy garden soil. not much calcium, but rather acid.
what are the conditions in south central US ?
much obliged, with best regards, edward|
I don't know the answer. I think soils in the US southwest tend toward the alkaline, but my own garden soil is probably slightly acidic, and this Eryngium does fine. On the other hand, the Dutch climate may not provide as much heat as this plant likes.
|Mary||Mar 09, 2010||My best info on germination is to sow in the normal way. Keep in a warm place for 2-4wks, then into the fridge for 4 weeks+, then back to ROOM TEMPERATURE, NOT HEAT. I am just about to try. They will be fine in reasonably alkaline soil|
|judy||Sep 11, 2011||Can this plant be used as a natural dye?|
I don't know - it's not mentioned as a use in what I've read about this plant.
- Seed from '05 trade. Baggy 70F (67%G, 11-16d)
- Seed from '07 garden. Baggy 70F (no G, 4w)
- Seed from '08 garden. Baggy 70F (25d) - 75F (27d; no G)
The plants in our '07 garden self-seeded, so there must be viable seeds set - but they are either few and far between, or their germination requirements aren't met by my attempts to start garden-collected seed.
