I started my seeds indoors the first week of April. They were 6" tall the last part of May when I transplanted them to the garden. They are now 3" tall. I seem to be going backwards. But I do have one in a pot that magically sprouted in January (I swear I didn't plant it). It is now about 3' tall and bushy with a couple blossoms.
Oh, I forgot to mention that the BLW's Mexican Night Primrose plants are covered with tomato horn worms. I didn't know they were a nightshade, or are they? I can't find them in the USDA website. Genus is Oenothera, a perennial. I checked my potted tomato, the potatoes, and the peppers and no worms there.
Oh, there it is, Mexican Evening Primrose, Oenothera mexicana, a member of the rosidae subclass???
