Everyone knows spider plants are super easy to grow. You hear tales of them volunteering even if not planted or becoming invasive when they are. I was enthralled by them on a visit my great aunt's when I was just a kid. She gave me seed, they didn't grow. Now, 40 years later, I still can't get them to even come up! No one in my immediate area grows them as far as I can tell. My only theory as to the cause is that it must somehow be related to pH levels. Is cleome an acid loving plant? I have neutral to base soil and long ago gave up on blueberries and other plants that need acidic soil.
