What's Blooming: Voodoo Lily

 


What’s Blooming:  Voodoo Lily
by Kelly Kellow, Horticulturist, Gardens on Spring Creek

 

One of the smelliest flowers in the world – Amorophophallus ‘Konjac’ or the Voodoo Lily – is starting to bloom right here at the Gardens on Spring Creek in the Butterfly House.  When in bloom, the flower is amazing to look at, but hard to stomach and be around it because of its revolting smell. 

But honestly, what is cooler than a plant that smells like death?  Amorphophallus ‘Konjac’ is one variety of the 80 - 90 in the amorphophallus family that is known for its flower that includes a spathe and spadix.  The flower resembles that of a calla lily where the spathe of the flower is simply a large, leaf-like bract that is brightly colored to attract pollinators.  The spathe surrounds and protects the spadix, that is a small spike covered in tightly packed flowers.  Together the spathe and spadix can grow anywhere from 10 to 50 inches long, depending on the age and size of the corm its growing from.

Amorphophallus ‘Konjac’ is not one of the largest, like its family member A. titanium, but is known for its dark purple flower.  It is native to very tropical areas in Asia and Africa where it used medicinally and as a food source.  The corm (a fleshy, underground stem) is dried and ground into a powder and added into dietary supplements for weight loss, or to make shirataki noodles.  The starch from the corm is used to make a popular Asian fruit jelly snack, yumm! 

Despite these uses, the plant is less likely to be eaten as much as grown for its unique flower and foliage.  In late winter, the corm comes out of dormancy and will first grow a flower stock that can get up to six feet tall.  This process takes about a month.  The spathe and spadex will fully open for a few days before it flowers.  The only way to tell it has officially flowered is when it emits the strong, offensive odor that smells like rotting meat. 

The reason behind this terrible smell is for the plant to attract its only pollinator, the Carrion fly.  Carrion flies are one of the first insects to arrive when an animal or human dies, where it lays eggs and starts the decomposition process.  Forensically, these flies help determine how long something has been deceased depending on the stages of the larvae.  The smell tricks the fly into thinking that it is visiting a cadaver and when it lands inside the flower, the fly pollinates the plant. 

The smell is strongest after one day of blooming and will linger for a couple more days in an area where there is no air circulation.  In the following weeks, the flower will fade back, and the corm will go into a second dormancy period.  A month after the flower has disappeared, the plant will then produce Jurassic-like leaves with multiple branches that resembles a small tree.  This part is not smelly and instead provides a jungle-like look.


The corm will go dormant for a second time from August to January and start the process all over again.  A. ‘Konjac’ can be grown at home in a container and is relatively easy to take care of.  When the plant is in either of its dormancy periods, the key is to not over water so as to not kill the corm.  The corm can be left in the soil with an occasional watering and it will come and go through its cycle naturally.  The flower can be bagged when in bloom to contain the smell. 

The Voodoo lily is a unique plant with its large smelly flowers and fun leaves.  Our Voodoo lily will stay in the Butterfly House until it blooms – come and smell it if you dare!

Hornworms by Brionna McCumber

Gardeners in Colorado may find large green caterpillars with an iconic horn on their plants every summer—these are hornworms! Tobacco hornworms ( Manduca sexta ) feed on common garden crops, often leading to conflict with humans. These very hungry caterpillars are defoliators, damaging plants such as tomatoes, peppers, potatoes, and eggplant. While the caterpillars use crops as a food source, which could be seen as negative, the moths provide a critical step in reproduction for the plants via pollination. Carolina Sphinx Moths ( Manduca sexta ), also called Hummingbird moths, are the adult form of hornworm s. They are known for their unique ability to hover mid-flight. Combined with the use of a special elongated proboscis, these moths are especially important for plant species with long tubular flowers that other pollinators cannot access or pollinate.  The Gardens on Spring Creek Butterfly House wants to highlight the importance of these specialized pollinators in our...

Winter Watering by Bryan Fischer

O ne of the brightest spots of living on the Front Range of Colorado is its winters. With more than 300 days of sunshine annually, we seldom see extended periods of the grey, chilly, precipitating skies common in so much of the country. It’s not unusual for daily highs to make it above 50 degrees. Much of this we have our elevation and distance from an ocean to thank – our sunlight is more intense than at sea level and our humidity lower, resulting in greater warming during the day compared to regions of similar latitude to our east or near a coastline .    Unfortunately for many landscape plants, however, that same day-night temperature differential spells trouble when paired with our lack of soil-insulating snow cover.  The resulting environment of warm days, frequent wind , and intense sun increases water demand, while low humidity saps the soil moisture reserves that our limited precipitation may provide. As a result, our landscape plants are predisposed to dehydration-indu...

Conifers: Pining for Something Different by Bryan Fischer

Evolving considerably earlier than flowering plants (angiosperms), conifers represent a long-lived and successful lineage of trees classified as gymnosperms. Gymnosperms were among the first true seed-bearing plants and evolved before specialized pollinators existed, so they are typically wind-pollinated. Seeds on these plants are produced between or on scale-like structures (think pine cone scales), rather than in fully enclosed structures, like tomato fruits. Gymnosperm, in fact, is Greek for “naked seeds,” so just imagine what that might imply for the origin of the word “gymnasium” … Long-lived, adaptable and attractive year-round, conifers represent a silver bullet of sorts for our Colorado gardens. Sadly, the overuse of just a few species and cultivars of these plants has given them a bad name. Don’t be put off – judicious use of conifers makes perennial plantings “pop” and provides structural bones during the fall and winter months.  Below, find a selection of underused, adap...
