The two plants I put in the greenhouse are doing slightly better and I've picked a few okra pods from them already. They are still only eighteen inches (50cm) tall, but at least they are showing me how okra is supposed to behave.
The flowers are rather like a morning glory and, like morning glories, they only last for a single day.
The flowers are self-pollinating - I love the velvety appearance of the stigma.
By the end of the day, the flower has shrivelled and the okra pod is ready to form.
