Can anyone tell me what this flower is? I think it's an outside vine. I couldn't find a forum for outside plant identification.
Hey alalso, that's definitely a Passiflora sp. There are many species and cultivars. I couldn't name which one, but we do have some very sharp people reading these forums who may be able to pin it down further. I think passion flowers are some of the most wonderful flowers we can grow. The form of the flower is striking, they come in rich hues of blue (and other colours - but the blues are amazing), some have intoxicating fragrance and some produce incredibly delicious fruit. The Plant ID Forum has two subforums, Indoor ID and NW Flower ID. When you click Plant ID the subforums appear at the top and the general ID (outdoor ID) appears below. I moved your post to the general Plant ID Forum.
