The Yellow Jessamine, looks from a distance like forsythia on steroids. By the end of March (central Arkansas) this flowering vine is on display everywhere: Mailboxes, telephone poles, gates, trellises, and homes. It appears to share common characteristics with the trumpet vine and appears to be called Yellow trumpet - or Evening Trumpet -on occasion. (A quick survey of the net shows several flowers under the Yellow-Trumpet name.) As is, the Yellow Jessamine is the State flower of South Carolina. According to Wikipedia, the flower is toxic, and NOT something to suck like honeysuckle.
