I would think you would just cover the seeds no deeper than the size of the hard seed...in nature, they sit on top of the soil. I'm no expert because I have seeds I want to try to propogate myself. Prairie Moon says they need a 60-90 day cold moist strat followed by a 60-90 day warm moist strat followed by a second cold moist strat or 2 years for germination! So that is probably why I haven't been successful with my seeds. The seeds I cold stratified last winter were out over the summer in their bag & are now in the frig again...so we will see if that works! I bought 2--3 gallon Hop Ash trees at Texas Discovery Gardens Fall Plant sale this month that weren't very big but the curator said that the first several years...the Hop trees establish their roots before growing bigger. Makes sense but the price was $25 each but I bought 2 anyway! I had tried buying them from Mossy Oak Nativ Nursery for cheap & they all died! Hopefully, these 2 will make it & thrive! I also bought a Prickly Ash after not having success germinating seeds I had collected from a friend's tree. I get very impatient! ;o) Good luck!

The numbered plants are those that somebody on the Butterfly Gardening forum has used to SUCCESSFULLY rear caterpillars to adulthood or has actually observed the caterpillar eating. If there is no numbered plant, then nobody on our forum can vouch for any specific plant. If a butterfly in the list below has no numbered plant, research the plant family shown for hostplant candidates. Several forum members report that using nursery or home-improvement store plants can be poisonous to caterpillars and adult butterflies due to pesticides or other chemicals. You have three main options: 1--raise the plant from seed (best). 2--prune the plant, do not put it in a prominent location, and wait for some new growth before presenting the plant to butterflies (good). 3--buy nursery/store plants, wash them thoroughly (fair; it is hard to get all the chemical off of the plant).

The list below are plants that have all been found growing and thriving in the wild of the most coldest gardening regions. Many have hybrids that have been bred from them...these hybrids generally will be able to also grow in the same plant zones and survive the same long and bitter winters. Please do research them if you're unsure of their hardiness in your particular zone or region, and as always, with any seeds that you're unsure can be Winter Sown in your region save some seeds to start indoors.

I can handle poison ivy without a problem but I get rid of it because others are allergic to it. I also only mess with poison ivy when necessary because I know that my immunity to it can go away as I age. The same is true with rue. Allergy to rue Hoptree is a small tree native to Missouri that hosts giant swallowtails and tiger swallowtails. It is easy to raise the caterpillars right on the tree using wedding bags. Golden Alexander is a plant native to Missouri that hosts black swallowtails. The leaves are much bigger than the usual plants people use for black swallowtails and that is why I never run out of food for my BSTs versus the many other people who do. But because it is tough to spot BST eggs/pillars on Golden Alexander, I also have other hostplants. I have learned the ideal time (end of July in my area) to plant dill seed so I can maximize the number of BST pillars I get to raise. Mama BSTs prefer to lay their eggs on the young dill and it is easier to spot the eggs on dill versus other BST hostplants. I also grow parsley the entire season. Has the side benefit of making my sister-in-law happy when I show up to her house with fresh parsley.
