Corpse Flower Watch: Day 12

Today, Lois measures just about 64.25 inches. Her vertical growth has slowed to only .75 inches since yesterday – this, plus the bright purple streak that appeared on the her right side and the fact that the bracts have fallen off completely (see image below), indicate that blooming is imminent!

And, we have some great news! The Cockrell Butterfly Center will be open around the clock for the Corpse Flower Watch until after Lois has bloomed – come by any time to see her! You can get tickets here.

Corpse Flower Watch: Day 11

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.

PC users: You need to have Windows Media Player to view our webcam video feed. (Download it here.) Firefox users: download this plugin. Mac users: we’re working on a solution for you; we’ll post again when we get it figured out. In the meantime, there is a converter plugin for Mac users available that you can try for free; get it here. If anyone tries it, let us know how it works in the comments!

UPDATE: There was an issue with the webcam feed on the night of Friday, July 9 due to an unintended change to our firewall. This issue is now fixed – thank you to everyone who let us know of the problem! If you experience any problems with the webcam going forward, please email blogadmin@hmns.org or send a message to @hmns on Twitter.

Mac users: Unfortunately, due to the unexpected nature of this plant’s flowering, we had to go with the equipment we had on hand – which is, also very unfortunately, several years old and limited to Windows drivers. We have tested several options to convert the feed, but none have worked with our equipment so far. We are trying to find a workaround, but in the meantime, KRPC Ch. 2 also has a webcam with a live feed of the Corpse Flower, and you can access it here.

We are very sorry for any inconvenience or frustration this has caused. If you are still unable to view the webcam, we also have photos, blog posts and videos with regular updates on Lois’ status.

UPDATE 2: We are getting reports that the webcam does not function in Google Chrome. We recommend using Internet Explorer of Firefox (with the plugin linked above) for the best performance.

The Amazing Amorphophallus – See It at HMNS!

The Cockrell Butterfly Center is pleased to present to you , for your viewing and olfactory pleasure: a celebrity among the plant community, the Amorphophallus titanum.

Measuring the Corpse Flower, July 3rd

Amorphophallus titanum, more politely referred to as titan arum or the corpse flower, has gained its celebrity status by having one of the largest, rarest, and smelliest flowers in the world. These flowers can reach heights of 7-10 ft and a diameter of 5-6 ft. Not only does the Titan arum boast the worlds largest unbranched inflorescence, its bloom is rare and unpredictable. This monumental flower bloom will be only the second recorded in the state of Texas, and the 29th in the United States.  However, in order to witness this rare spectacle, viewers will have to endure the epic stench that has earned this magnificent bloom the nickname, “Corpse Flower.”

A. titanum, now endangered in the wild, is native to Sumatra, where it grows on limestone hillsides in rainforest clearings. A giant relative of our native Jack-in-the-pulpit and calla lilies, the species was first discovered in 1878 by an Italian botanist, Odoardo Beccari. It first flowered in cultivation in 1889 at Kew Gardens in London, England. The first flower in the United States bloomed in 1937 at New York Botanical Gardens. This event created such a stir that the police department had to be brought in to handle the crowds. Since 1937 there have been a total of 28 recorded flowerings at botanical gardens and universities across the United States, with the same plant very rarely blooming twice.

The corpse flower grows from an underground corm, that can weigh as much as 200 lbs. Every year the corm shoots up a single branched leaf that looks more like a small tree, reaching heights of up to 20 ft, and then dying back again every winter. This process repeats until one year the corm is large enough and conditions are right. Then it shoots up a single giant inflorescence, which grows at an astonishing rate of 4 to 6 inches per day. Like a calla lily, the inflorescence consists of a central spadix (where the pollen and ovules are produced) surrounded by a leafy spathe.  Once fully opened, the yellowish spadix of the corpse flower heats up to near human body temperature and emits an eye-watering perfume that has been described as smelling like a decomposing carcass.  The spathe peels away from the spadix to reveal its inner surface, which is the purplish color of rotten meat.  This appearance and the strong, putrid odor function, in nature, to attract the carrion beetles that are believed to pollinate this smelly beauty. Although little is known about the process in the wild, it is speculated that the plant somehow traps the beetles for up to 24 hours to ensure successful pollination.

The entire flowering process takes a little over a month, but once opened, the flower is very short lived. In fact, the smell may only last for 8 to 12 hours, and the flower may begin to decline within a couple of days.  If the plant is successfully pollinated, the spathe will fall away first, revealing on the bottom part of the spadix the bright red fruits that contain seeds for new baby corpse flowers. Once the flower dies back the plant may not flower again for many years, if ever.

Eddie Holik, former director of horticulture for the Cockrell Butterfly Center, purchased the corm of our corpse flower from Plant Delights Nursery in 2004.  The corm cost $75, and was only about the size of a walnut.  Since then the plant has shot up 5 leaves, each one bigger than the year before.  We have weighed and measured the corm each year during its dormant period. This spring (2010), the corm weighed exactly 30 pounds and was 14 inches across.  In late April, instead of producing a leaf as usual, it began shooting up a flower bud.  The bud is currently 50 inches tall, and growing at a rate of about 5 inches per day. Judging by recorded growth rates and pictures from other titan arums that have bloomed, we are predicting that the flower will be fully opened late this week or early next week, i.e., around July 10 or so.  Keep checking the blog, as we  will update it daily with the most current predictions.

In keeping with the tradition of naming these magnificent flowers, we have named our titan arum Lois, in honor of Eddie’s mother, who worked in a flower shop and was an avid gardener.  Eddie credits her with being the inspiration behind his pursuit of a career in horticulture.

So please join us in the Cockrell Butterfly Center to witness this literally breathtaking, and possibly once in a life time experience.
