Corpse Flower Watch: Day 11

Corpse Flower’s growth

Today, Lois measures 63.5 inches. Her vertical growth has slowed to only 1.5 inches since yesterday, but at her base she has grown 4 inches in circumference. When we first measured her circumference last week, it was 14 inches; today, it’s 34 inches.

This implies that her vertical growth is almost over and that Lois’ bloom could open anytime in the next 24 hours, most likely sometime this afternoon.

    Is the butterfly center going to be open late if Lois starts blooming this afternoon?? can you please post how late. i wanna see her!!!!

    also, what will she look like tomorrow? or the day after?



  2. Erin F says:

    Hi Courtney! We will be open until midnight tonight and we are reopening at 6 am tomorrow, regardless of whether Lois blooms today. We will likely have extended ours until after she blooms.

    If you’d like to see some photos from the life cycle of a corpse flower, check out the link below – these are photos of Jack, a corpse flower that bloomed at SFA university.

    Just wanted to say that I’m waiting on pins and needles for it to bloom and excitedly watching your webcan, flickr, twitter and blog updates! Thanks for all the updates on those sites. We are hoping to drive to Houston on Monday to see it.

  4. Erin F says:

    Hi Susan! So glad you are enjoying the updates! Hope to see you Monday!

    I’m staring at this webcam too much! When the flower begins to “open”, how long does the process take ? i.e. if I see more “unfurling” around the center stalk on the live feed, how long before the flower is wide open and laying out in full circumference?

  6. Brian says:

    I see from the webcam that it has not bloomed yet. What is the current prediction now?

  7. N Vogel says:

    The webcam is not operating. I was watching earlier just fine. Now it is just a blank screen. What is going on? I’m not able to get to HMNS in person. I am relying on the webcam to keep updated. Please check it out and get it running again. Thank you.

    I am a palynologist at BP and member of the American Association of Palynology. I am very interested in obtaining a sample of the pollen from the plant for the CENEX (Center for Excellence in Palynology) collection that is housed at Louisiana State University. Is there anyway to get a small sample? What we typically do is mount the pollen on a small microscope slide. This would be a spectacular addition to the collection.


  9. Erin F says:

    Hi Rebecca – I will forward this request and your contact info to our butterfly center staff – I am sure they will be in touch with you!

  10. Erin F says:

    Hello! So sorry about that. The webcam was down briefly due to overwhelming traffic to watch it. We’ve reduced the size of the feed that shows in an effort to let more people view it simultaneously. Please let us know if it works for you know.

    Also, you can follow updates at the sites below – we’re posting information photos and video as Lois develops.

  11. Erin F says:

    Hi Brian,

    We are thinking tomorrow afternoon – it seems that the bract (the leaf that is currently bent over in half in the front) is hanging on by only a thread. Most other corpse flowers have bloomed as soon as the bract falls off, and typically in the afternoon.

    Crossing our fingers!

  12. Erin F says:

    Hi Scott,

    I’ve heard that it can take anywhere from 3 – 8 hours to completely unfurl, once it begins.

  13. Carol says:

    I was at the museum today and I am checking on Lois’ progress. I am planning to come by there again Monday afternoon if she has opened. can’t get your blog to work.

  14. chris says:

    What will the hours be for Monday? I am hoping to stop by after work today??

  15. Brian says:

    As of this morning, is an evening bloom tonight reasonable?

  16. scottF says:

    I think it died. ;^)
    Time for some CPR (corpse plant rejuvination)

  17. Erin F says:

    Hi Carol,

    Did you mean the webcam isn’t working? Unfortunately, only a certain number can see the feed live at any given time; try waiting a bit and checking back. Sorry for the inconvenience! In the meantime, we are updating the following links regularly!

  18. Erin F says:

    Hi Chris,

    The Butterfly Center is now open around the clock, until after Lois blooms – come by when you can!

  19. Erin F says:

    Hi Brian,

    Yes! As you can see from the photo linked below, Lois is starting to turn purple on the outside – a sign of imminent bloom!

  20. Brian says:

    If I come tonight, what should I expect to see? How open do you predict it will be at this point if I come around 9-10 pm?

  21. Brian says:

    Ignore the previous comment please. Assuming it blooms very soon, how open do you predict it will be at this point if I come around 9-10 pm? Is it more likely that it will be in full bloom tomorrow, as it will could only just start tonight?

  22. Erin F says:

    Hi Brian,

    It may only just be beginning to bloom tonight, if it does. Check out this photo:

    If it does bloom tonight, it will be fully open tomorrow – so if you want to see it fully open, come then. Of course, you can always come in the middle of the night – we’re open around the clock at the butterfly center for the Corpse Flower Watch!

  23. Robin says:

    So glad you’re keeping the cockrell open 24/7 – this is so exciting. We’ve been watching since our visit last Thursday. I’m assuming still no trace of the scent?

  24. Erin F says:

    Nope – no stink yet! But possibly tonight. Check out our new video!

  25. Brittany says:

    does the stench last as long as the bloom? which i was told is 24 hours..
