Strange event in the zinnia bed
This year I planted three trays of 3" pots of zinnias, two varieties to a tray. The best germination by far came from the tray containing Isabellina (a cream-colored cactus type) and Exquisite (blooming red maturing to pink).
They lingered in their pots longer than I would have liked because I got sick in late May, but eventually they were all planted out. I saw lots of Exquisite in bloom, but not one Isabellina. I did see a great many bright yellow single zinnias. I remarked to people that I had many more yellows than usual, but it didn't occur to me until this morning that perhaps the yellows were actually Isabellinas gone awry.
I've read that some zinnias react to transplanting by reverting to the single form. Could they also change color? the Isabellina seed packet describes it as "creamy yellow." I would have called it "cream." The zinnias in my garden are a hot, school bus yellow--nothing creamy about them. Do you think they could be Isabellinas?
