Thanks, Alberto, for all of your good information. I use color coding to identify which plants bloomed which years. If the end is pointed (originally turned upside down in pots), it didn't bloom that year. If I turn it to the roundish end, it did. Each color denotes a different year, so if I have a blue, a pink and a yellow label in the pot, I have a 3-year record of its bloom. If I am really sharp that year, I write the bloom month, indicate transplanting or division (with an X) and occasionally the color on the colored label. Just another use for those labels!
