Peter Grande - Plant Delights' First Amorphophallus titanum Bloom at Juniper Level Botanic Garden

Thanks to all who visited and watched online! We will post a complete video of Peter's first bloom soon!

Plant Delights Nursery at Juniper Level Botanic Garden is excited to announce its first flowering of the rare Titan Arum...Amorphophallus titanum, named Peter Grande. The trend of naming Amorphophallus clones is both a great way to keep track of flowering clones as well as a source of great amusement. Some of the more unusual names include Audrey, Rotney, The Amazing Stinko, Carrion My Wayward Son, Pepe Le Pew, Morticia, and Pewtunia.

Our Titan arum flower began to open on July 6, 2018 around 1:30pm. This coincided with the first weekend of Plant Delights' Summer Open Nursery and Garden Days, which were July 6-8 and July 13-15 that year. The nursery was open extended evening hours until 8pm to allow ample opportunity to witness this rare horticultural occurrence.

Amorphophallus titanum has a larger than life reputation because of its enormous floral show…the largest unbranched inflorescence in the plant kingdom, ranging from 3' to 12’ tall. The inflorescence, which is often called a "flower", remains open for only 24-48 hours.

Native to the understory of the Sumatran rainforest, where it is considered a highly vulnerable species, Amorphophallus titanum has been in cultivation since at least 1889 when a specimen flowered at the UK's Royal Botanic Gardens, Kew. Since then, just over 570 Titan Arums have flowered in cultivation worldwide, with just over 350 of those being in the United States.

The Plant Delights specimen, Peter Grande, was the ninth to flower in North Carolina. In 2005, Plant Delights Nursery learned that UNC-Charlotte Botanical Gardens had lost their large Amorphophallus titanum due to a winter greenhouse heater failure, so it donated its largest specimen to the gardens, which flowered there in 2007…the first recorded flowering of a Titan Arum in North Carolina. Our current flowering Titanum is 8 years old, and was propagated here from a leaf cutting. We have compiled a list of known Amorphophallus titanum flowerings in cultivation.

Juniper Level Botanic Garden is a research and conservation botanic garden, supported currently by Plant Delights mail order nursery. To ensure that the garden and its work remains viable, our endowment is set up through the NC Agricultural Foundationat NC State University. To contribute, make checks payable to NC Ag Foundation and specify Juniper Level Botanic Garden endowment. Checks can be dropped off at the nursery and garden or mailed directly to NC Agricultural Foundation.
