Wish I had purchased this variety elsewhere

Take note of seed quantity- this is expensive seed though I don't understand why. I purchased from BI due to convenience of ordering other seeds from them. Normally happy enough with their products but you can find this particular seed for a better price and much larger quantity elsewhere. The biggest frustration to me was the packaging. It comes in a very small foil lined package that as I unfortunately discovered, isn't the most secure while you're using it. It's hard to tear it open for a clean edge to easily dispense seed so it takes much more fumbling than normal. I carefully set the package down in between planting seeds, and it tipped over. As a result of the package being so small the seeds fell out and I lost 80% of the seeds. So frustrating! I couldn't find and recover them from the grass next to the planting bed! I realize this accident is not Botanical Interests' fault, but if the packaging envelope had been consistent with other seeds from them this would not have happened. Just a fair heads up to others who purchase to be extra careful not to let this disappointing accident happen. I hope I get good germination from the few that I planted! Out the gate I am deducting 2 stars on this one for price and packaging.
