Visitors at Kew Gardens in London are captivated by the peculiar aroma emanating from the greenhouses, as the Corpse Flower, scientifically known as Amorphophallus titanum, reaches over 2.5 meters in height and blooms for the first time in several years.
The allure of this exotic plant has garnered global attention. Memorable is the experience of witnessing a flower that can truly be compared to a star in the botanical universe. Kew staff frequently gather to snap photos and take in the unique scent. Initially subdued, the odor intensified, creating an unforgettable atmosphere.
As we gathered around, we discussed the smells with a level of sophistication akin to expert sommeliers. Comments ranged from “It has a leftover quality” to “There’s a hint of stale cabbage,” with classic undertones of decaying meat.
This rare flower blooms only once every 7 to 10 years. If you missed the opportunity this time, don’t worry—Kew Gardens currently hosts around 15 A. titanum specimens. Keep an eye out for your next chance to see (and, more notably, smell) these fascinating plants!
Amsterdam’s tiny street gardens provide habitat for insects

A study of small urban gardens in the Netherlands found that they can be havens for insects and other wildlife. The two most effective factors were having a lot of plants and a wide variety of plants, whether or not the plants were native.
“Even in a really small garden, just a few plants can make a big difference.” Joe Morpurgo At Leiden University in the Netherlands.
Morpurgo says there have been some studies on biodiversity in larger gardens, but virtually none on smaller ones, so in 2019 his team surveyed 65 urban gardens in Amsterdam and The Hague, all measuring less than 10 square metres.
The researchers measured factors such as the total number of insects, the number of different species, whether the plants were native, and the area covered by the plants. Plant cover was calculated by adding up the area covered by individual specimens, so the garden’s cover can be greater than the area of the land due to plant overlap.
The researchers found that insect abundance and species richness were strongly correlated with plant cover and plant richness, but surprisingly, neither garden size nor native plant cover made any difference.
In theory, native plants should be better: Pollinating insects often adapt to particular flower shapes, and some plant-eating insects will eat specific varieties.
There are several possible explanations for why the proportion of native plants had no effect, Morpurgo said. For example, insects that breed in cities could be omnivorous, or many of them could be invasive species (the study did not categorize insects as native or not).
A study on the large-scale gardens of Wisley, England produces almost the same results“The more plant matter there is, the more invertebrates there are.” Andrew Salisbury These studies were led by staff from the Royal Horticultural Society (RHS).
But one RHS study found that native plants could support slightly higher numbers of plant-eating species, such as caterpillars, Salisbury said.
Morpurgo said he would continue to encourage people to grow native plants, which he said have many more benefits, including cultural value as well as helping insects.
His main advice is to do nothing and just allow plants, even those we might call weeds, to grow and attract wildlife: “If you leave everything alone, nature will come into your garden,” says Morpurgo.
This gorgeous, but smelly, corpse flower bloomed on June 18th. Royal Botanic Gardens, KewIn London however it tends to be only for a short period, lasting only 24 to 36 hours.
Corpse Flower (Amorphophallus titanium) also known as Titan Aramgets its name from the foul smell it gives off, resembling rotting meat, which is so strong it can be heard for hundreds of metres. The smell is produced to attract rare pollinating insects, such as flesh flies and carrion beetles, to the short-lived flowers, and must be strong enough to do its job during the short period the plant is in flower, because the plant may not flower again for many years.
Strictly speaking, this up to 3 metre tall plant isn’t one flower, but many. The inner inflorescence, or spadix, emerges from a purple, pleated collar called a bract and looks like a yellow obelisk. The inflorescence, or cluster of flowers, lies in the protected area between the bract and the spadix.
If you happen to see and smell it, the smell may not be what you expect: it can change during the flower’s short lifespan and can smell like rotting flesh, as well as pleasant excrement or warm garbage.
This rare plant is endemic to the rainforests of the Indonesian island of Sumatra, but is cultivated in many botanical gardens around the world for its beauty and the crowds it attracts when it blooms. The first time it is known to flower outside of Sumatra was in 1889 at Kew Botanical Gardens.
