An annual sow thistle “volunteered” to grow in one of my pots and I let it. I nurtured the pseudo-dandelion and it was thriving for a while. The bright yellow flowers blossomed in abundance. Green leaves unfurled and stretched toward the sun. And then the plant started to die, for whatever reason. I’ve deadheaded the blossoms, removed the brown leaves, and continued to water it according to the guidance of my plant app. But the plant is still dying.
