Growing conditions for Rattlesnake Master?
Hi, I'm not a regular on this particular forum, but I wonder if some of you will help me out. I just received a Rattlesnake Master (Eryngium yuccifolium) plant, and I have been online looking for its preferred growing conditions. The advice has been all over the map.
I have poor, dry, sandy soil that drains like a dream. Lavender and dianthus grow well here. I have set up a few lasagna beds for plants that require richer soil.
Based on the appearance (spiky, fat leaves) Rattlesnake Master likes blazing hot FULL sun. I think I got that part figured out.
How rich should the soil be? What about moisture? I have read a lot of conflicting information.
