Comments regarding Stellar Seeds

I purchased Golden Purslane and Bedford Champion onion seeds in B.C. The purslane (planted in hot weather) didn't sprout - which could be my fault, as I haven't the slightest idea how to grow purslane - but the onions practically jumped out of the soil. I planted them at the same time as some Pacific Pearl scallions and some Walla Walla's, which have yet to come up. Unfortunately, I don't know whether the Bedford Champions will overwinter or not, as no growing information is provided on the packet. I would buy their seeds again.
