Hey, I found some seeds from my grandmother's house and need to 'chemically scarify' them. I find that this means soaking them for at least half an hour in concentrated sulfuric acid before planting them. They are Texas plants and stand little enough chance here anyway but apparantly no chance at all if I skip this step. I have no idea where to start looking sulfuric acid in English, much less Swedish. Can someone please help me??

Okay, I know Texans are supposed to be tough, but seeds that need to be "scarified" in acid first?? What are they seeds for, if I dare ask  |

Bluebonnets
"To ensure rapid, high percentage germination, the bluebonnet seed has to be treated to remove inhibiting properties of the seed coat which otherwise prevent water uptake and the initiation of growth. This process of seed treatment is referred to as scarification. Seed which has been properly scarified will germinate within 10 days after planting in a moist soil. Seedlings of scarified seed are also more vigorous."
".... if common bluebonnet seed is used which has not been chemically treated (scarified), one doesn't have much chance for success. The germination of non-scarified seed is sometimes less than 20 percent. This means that assuming you do everything correctly (pest control, optimum moisture), one could only expect, at best, 20 seeds to grow out of every 100 planted using non-scarified seed. Also, one can't even expect all of those 20 seeds to sprout simultaneously as sprouting may occur over a 30 day period. The availability of chemically scarified seed solves this age-old problem. "

hmmm...can you try a test..... in australia many of our seeds need to be scarified...but we can do things like use sandpaper to do that..weaken the outer seal of the seed coat and then they can be soaked for a period of time before planting eg 12 hrs soaking, 24 hrs.......but i am supposing these seeds must be small for need of chemical scarification....anyway try roughening some up and then soaking in water for 12 hours ( hot not boiling water).. and see how that goes...

I know that this isn't supposed to be a joke, I just had an image of Pam standing in a kitchen with a seed the size of a poppy seed trying to sandpaper it. It was a funny image for a split second. ;D
Have you tried looking onto some gardening websites, and typing in "bluebonnet?"
Better Homes and Gardens (bhg.com)
Home and Garden (hgtv.com)
iVillage.com (this is more a general website, they do have gardening tips though)
