I ordered “hardy hibiscus” seeds which, based on pictures (yes I know), were hibiscus moscheutos. It was an Amazon purchase which is risky anyway; the seller was an American seller but somehow the seeds arrived from an East Asian country (China?) based on the shipping time and script on the label. Lots of plant matter was still mixed in with the seeds. Amazon issues aside, I went ahead and planted them in a sterile mix to see what would come up. Two kinds of seedlings are coming up. It is my belief that the seedling with the rounder cotyledons is hibiscus moscheutos, or at the very least is a form of hibiscus. I am not sure if the other type – oval cotyledons and long toothed true leaves – is a hibiscus at all or is just a weed that was mixed in. Any thoughts?
