BLACK-EYED SUSAN
Rudbeckia hirta
REMEMBER: It is an offence to pick wildflowers in any provincial park.
The Black-eyed Susan, also known as Brown-Eyed Susan or Gloriosa Daisy, can be an annual, a perennial, or even a biennial. This is common summer-time blossom of Algonquin Highland roadsides. A member of the huge Aster family, it has daisy-like flowers, with an outer ring of bright yellow petals and a central purplish-brown receptacle composed of many disk florets. The average blossom size is 7.6 cm in diameter, with 10-20 diamond-shaped petals. They grow straight or erect, with bristly stems, to a height of 0.9 m. Its hairy lance-shaped leaves are 5 to 7.6 cm long.

Along roadsides, open fields and clear woodlands is where Black-Eyed Susans love to grow as they are fairly drought tolerant. Butterflies of many species are attracted to them.
