Yep, that’s right ladies and gents. The giant pumpkins are so big, a man can fit inside. Matthew DeBacco from team-pumpkin.org climbed inside Steve Connolly’s 1,674.5 pounder this morning to harvest some seeds. He reported that it was nice and warm, and that if it were on the Lower East Side it would rent for about $1,500 a month!.
How Do Insects Feed on this Plant with Sticky White Latex?

When I was in graduate school I decided to turn my East Village community garden plot over to the insects. I was an NYBG/CUNY Ph.D. candidate hoping to study plant-animal interactions. By happy accident I ended up in an entomology course at the American Museum of Natural History. The revelation that plants produce a huge variety of chemicals capable of manipulating insect behavior captured my imagination, so I planted six native species: three milkweeds (Asclepias) and three goldenrods (Solidago) to attract specific beetles.
Fifteen years later, one goldenrod species is still hanging on, but common milkweed (Asclepias syriaca) is clearly the winner—and it’s now making furtive advances into neighboring plots (the original plant probably spread by underground rhizomes). My observations have convinced me that the common milkweed is anything but common!
Plants in the genus Asclepias are called milkweeds because of the sticky white latex that pours out of wounded tissues. Asclepias latex is rich in toxic cardiac glycosides, and the scientific genus name comes from Asklepios, the ancient Greek physician.
Some milkweed-feeders actually sequester the toxins to defend themselves from predators, but how do they avoid getting their mouthparts hopelessly gummed up? Some slice right through leaf midribs, which diverts the latex flow and enables the “trencher” to feed downstream of the cut.

It seems hard to believe, but the holidays really are just around the corner. We love the holidays here at The New York Botanical Garden. The holidays mean the return of one of New York City’s most cherished family traditions,The Holiday Train Show in the Enid A. Haupt Conservatory. It also means the arrival of beautiful new goodies at the Shop in the Garden, and on the Shop’s website. The selection of gifts in the Shop this holiday season is all about favorites, but they’re not just ours. We’re inviting some of the Garden’s most stylish, culinarily-minded, crafty, and green-thumbed friends to share a few of their favorite things with you!
So, take a spin around the Shop, whether in person while you’re visiting the giant pumpkins this weekend, or virtually. And if you happen to spot something that you’d like to call your favorite, you can use the “Tell A Friend” feature to give Santa a gentle hint.
So watch this space to see what some of your favorite bloggers will be giving as gifts this holiday season!
In the meantime, here are a few of my favorite things.
What will the pumpkin end up looking like, and will Cully break his own World Record? Only time will tell. But we do love daydreaming here at the Garden. So to get your imagination going about what the great pumpkin might end up looking like, we thought we’d share a few pictures of Cully’s past creations.

I am especially excited that three record-breaking pumpkins are on display this month at The New York Botanical Garden. The heaviest one is not only the heaviest fruit ever grown, but also the heaviest fruit in the plant kingdom! The scientific name of the species, Cucurbita maxima, says it all. How did this all come about?
First, I should explain my relationship with these plants. I work here at the Botanical Garden with Michael Nee on the taxonomy of the genus Cucurbita. This group of a little over a dozen species includes the squashes, pumpkins, and certain kinds of gourds. They all originally grew wild in the tropical and subtropical Americas. Five of the species were domesticated and represent some of our oldest New World crop plants. This means that Italy not only didn’t have tomatoes before Columbus, but no zucchini!
Wild Cucurbita fruit are like a baseball in size, shape, and even almost in hardness. This is quite large for a wild fruit, although nothing to write to the Guinness Book of World Records about. So how could a fruit that is so hard and so big travel around enough to form new populations? Wild Curcurbita do often grow in flood plains, and float during floods, but they would then only float in one direction: downstream.
Anyone who thinks Halloween Hoorah—The New York Botanical Garden‘s annual celebration of all things Halloween and pumpkin–is just for kids clearly did not see the look on my fiancé’s face on a recent Saturday. Maybe it was the generous wine samples we had just enjoyed at the Edible Garden’s finale weekend, or maybe it had to do with the fact that she’s been bringing up having children more often, and more insistently. Either way, her expression of delight as we walked through the Everett Children’s Adventure Garden was unreservedly enthusiastic, and, to a man who has been dealing with the daily headaches of having just moved into a fourth-floor walk-up, this change in mood was entirely welcome.

Last week I blogged about Doug Tallamy’s book Bringing Nature Home and the natural life cycles and interdependence among species in an ecological community. What happens when the balance of nature is disrupted?
The problem usually arises when an invasive species comes in and completely overturns the equilibrium—a process in which humans are intimately involved.
Not only are we generally responsible for introducing exotic, invasive species, we also mangle the environment with construction equipment, paved roadways, big lawns (a great American monoculture), and other means that disrupt natural communities. These disturbances provide invasive species with an ideal opportunity to colonize.
