I know this is gonna sound wierd ... are there different types of four o'clocks? I have some plants that I grew from seed that have the typical small black grenade looking seeds. Then I have plant that was rescued out of someones garbage that was a (root? tuber) and when planted produced flowers like my other four o'clocks but had larger heart shaped leaves and these seeds are larger, smooth and more of a brown color. Can anyone out there help me? I've searched theseedsite and cannot find anything there.

Thanks christina
