State Flower of Maryland

  • In 1918, Black-Eyed Susan was declared the official State Flower of Maryland.
  • You can easily spot the State Flower on roadsides and fields in Maryland. The colorful yellow-gold petals encircle a large black center. The gold and black color combination also match the state cat, bird, and insect. 
  • There are over 90 varieties of Black-Eyed Susan. It is also popular as Coneflower, because of its cone-like centers. 
  • Usually, it stays in a basal rosette form for the first year and then produces upright branching stems with blooms in the second year.

How to Grow the State Flower of Maryland?


Where to Grow

The State Flower of Maryland grows best when exposed to full, bright, direct sunlight for 4-5 hours. If you live in a hot zone, it would be best to give it shade from the intense afternoon heat. 

Best Soil

This beautiful wildflower is not picky about the growing medium and thrives well in average, well-draining soil. All Rudbeckias can tolerate various soil kinds, from loam to clay. Also, add organic matter to help retain moisture. 


Water the State Flower of Maryland whenever the top 2-3 inches of the soil feels dry to the touch. If the leaves droop, you should know the plant requires deep watering. 


Do not overfertilize the State Flower of Maryland, as it will weaken the stem, inhibiting flowering. Use a slow-release, all-purpose fertilizer of 12:6:6 blend, diluted to half the strength, 1-2 times a year.


If you deadhead these flowers, they will bloom longer. Cut off faded, spent, or dried-up blooms. 

Pests and Diseases

Although Black-Eyed Susan is rarely susceptible to severe pests and diseases, it can be attacked by two fungal diseases – Angular leaf spots and Septoria.

Remove dead, damaged, or infected plant parts to bar the spread. Do not wet the leaves, and provide good ventilation to the plant.
