Flower Fest - R for Rudbeckia fulgida
Rudbeckia fulgida or the Black-eyed Susan, as it is commonly known, is a very popular flowering plant. It is an easy-to-grow perennial that is native to the US. It is loved for its bright yellow/orange ray florets and its cone-like head of dark disk florets.
I have some rudbeckia seedlings that are about 7 weeks old now. So when I found out that this plant spreads aggressively by both rhizomes and seed, I wondered whether I am going to have another mint on my hands! 
Rudbeckia blooms from mid to late summer into fall. It does well at higher temperatures. So the hotter the summer, the more the blooms! By winter, if the flowers are allowed to go to seed, the finches will have a field day as this is their favorite food.
This is my entry for the letter R in the Flower Fest - the A - Z of Flowers.
Flower Fest is the brainchild of Nature & Me and Sree. Every two weeks, the focus will be on a letter of the English alphabet. The current letter is R. I am submitting photographs of flowers as my entries.
