This has been in the process of opening for a number of days now, and still going. Rate of increase in height has been 15 cms per day the last few days. Current height mid afternoon today is 201 cms from soil level to tip top. That's an increase of 8 cms since 8:00 am today, around a cm per hour.

Anyone care to guess what it is before it fully opens? (TROPICNUT IS NOT ALLOWED TO PLAY, sorry Dave, you know the answer already.) It's to the right of the ladder in the second pic if anyone is unsure of what's being referred to.
