This forsythia has a nice plant texture and foliage coloration for the genus and a compact habit. It is tough and handles heat or lack of rain quite well. The flowers appear more delicate like that of a cherry tree because of the big size of the blooms. It does bloom from ground to tip on any growth.

I have only one issue that has attacked one of my plants. Stem blight continued to wipe one plant out, branch by branch. Pruning and sanitizing didnt stop it from spreading and taking out branches all the way to the ground. The best thing to do is if you notice a branch wilting remove it and treat it immediately to prevent it from spreading. The plants won't wilt from drought under proper care so if you see wilting, get er done.

Forsythia - Show Off Forsythia

Interested in seeing a stellar fireworks show before the 4th of July? This little beauty will be a blast of early spring color from the ground up! Show Off is not your typical Forsythia! This variety is a vast improvement over all. It has intense yellow flowers, dark green foliage, with a round and compact form, so there is no need to prune. Older varieties can become out of control and often become victims of pruning. Now you can have your hedge - tight and compact the way you want it without doing any work. Show off your colors with Show Off, an abundant of large golden-yellow showy flowers. It will just put a smile on your face.
