Forsythia blooms with quince and just a couple of weeks after the fragrant paperbush. All prefer a little shade but can handle a good amount of sun. Show Off and Show Off Starlet have brighter and more abandunt blooms than the old types of forsythia. We prefer to trim them each year as their flower structure is more pretty the following year. I put links of everything mentioned here in the 'goes well with' section just below.
