New to me in October 2020 for the Winter Holidays.
I planted the bulb immediately, but it didn't bloom until late May 2021: https://pbase.com/britestar/image/171763514
That was strange.

After the first holiday season blooming, I allow all of my older amaryllises to bloom whenever Nature tells them. That usually is in May if they're going to bloom that year. Some only bloom every other year. I have no idea why I now suddenly have 3 Amaryllis plants blooming in July this year. All are being grown indoors.
