Wisteria a hardy climber. Seen here in the pretty purple colour. There are many varieties and I do not know which one this is.. possibly the Wisteria floribunda – the Japanese Wisteria. Family: Fabaceae (Pea family)
They are said to grow vigorously and need to be controlled. And the blooms seen here are really worth it. The pictures here were taken of the flowers allowed to trail down the roof of the London Apprentice – the popular pub in Isleworth. For more info check this link
I am sure this belongs to the Gourd family. But which one? Hopefully I shall see the fruit sometime ( it is not growing in my house). Correction – could be the pumpkin as Swaram has pointed out – same family though – Cucurbitaceae
Botanical name: Cucurbita pepo Family: Cucurbitaceae (Pumpkin family)
Synonyms: Cucumis pepo
Will write more about the vine after hopefully confirming the fruit.
