If you are of a certain age you may remember Screaming Yellow Zonkers, a kind of sugary carmel corn packaged in a black box. I am always reminded of the name at this season of blooms of brightest yellow.
Here are some yellows for Garden Bloggers Bloom Day. To see more visit Carol at May Dreams Gardens who hosts GBBD on the 15th of each month.

An Epimedium with large flowers that self-seeds: Epimedium grandiflorum ssp. koreana 'La Rocaille'
