The amaryllis travelled all the way to Haywards Heath with us https://365project.org/susiemc/album-1-year-5/2021-12-23 remember? While we were away it grew very tall (which made it much more difficult to transport it home safely) and this is what it looked like when we got home.
I was just thinking, Wow! that grew a lot in the last few days! You may need to stake it or give it some extra support so it doesn't tip over. It would be a shame to have it come to grief before it opens.
