During summer, there were butterflies on Stachytarpheta which we call
Those long spikes hold many seeds. I snipped off a mature one and planted seeds
earlier in the season. Nothing.
Today I found little plants in the path.
I am pretty sure they are Porterweed. This is how I got the red
Porterweed back last summer, found seedlings.
Comparison with the big plant. No doubt. How did they get there?
We had minor flooding during July and August. Seeds probably washed up.
I always save some seeds of Madagascar Periwinkle.
I never need seeds, they always reseed.
Periwinkle seedlings are late to emerge. Purchased plants planted too early will not thrive. They are happy hot-weather plants.
Like Melampodium, no dead-heading is required with Periwinkles,
old blooms shed and new take their place higher up the stems.
