I love this plant. Just bought a baby one in a 4 inch pot. I put it in a 6 inch pot and is about 2 ft long..... how long before it will bloom?

the plant in the photo IS A. grandiflora, nothing else. anyone who confuses a. g. braziliensis (sp?) should take another look at it.

In our Community Garden, where the street end is landscaped, the Dutchman's pipe (variety gigantea) gets more coments than any other plant, when the garden is open for tours. I could have found homes for hundreds of cuttings, if I had had them. It was particularly interesting to school children and teachers.
It WILL climb up anything available, including oaks, and like an exuberant puppy, must be restrained.

What fun!

Ah, Jasmine (comment above) beat me to this. I also think the photo is mislabeled.

I have had a Gigantea from Logees for several years. It has bloomed several different times and they don't look like the G. Braziliensis.

According to this photo, this flower looks like Aristolochia gigantea braziliensis...not the standard gigantea. A. grandiflora has more of a yellow background and has a very long tail. Check out

Spectacular huge flowers that look like a turkey´s neck, formed only by a showy red calix with white spots and a yellow center. Some say that they don´t smell good, but I never sensed any smell from it
