Plant information

Black-eyed Susan is a native garden ornamental that is easily recognizable. You can’t help but smile when you see a batch of the bright yellow daisy-like flowers with the beautiful brown centers bobbing in the breeze.

These biennial wildflowers easily reseed, and are best suited to areas of disturbance where you want a short lived perennial that will fill in while waiting for some of the long-term plants to establish. Ideal for a cutting garden, these flowers hold their bloom longer if given afternoon shade but are able to tolerate everything except wet soils, as well as being heat and drought tolerant.

Rudbeckia hirta serves as a larval host plant for the Silvery Checkerspot, as well as 14 other Lepidoptera, including the super cool looking Wavy-Lined Emerald Camoflaged Looper.

stratification code
C(30)

A	Seed should germinate when sown in a warm location.
B	Hot water treatment: Bring water to a boil, remove from heat, pour over seeds, and soak for 24 hours.. Generally this is for seed with a thick seedcoat.
C	(# of days of cold moist stratification) Seeds germinate after a period of cold, moist stratification. Mix seeds with a handful of damp vermiculite or clean sand (moist—but not wet). Place mixture in a sealed plastic bag and store in a refrigerator, NOT the freezer.
D	Sow on the surface of the soil. Generally these seeds are very small.
E	These seeds need a 60-90 day warm, moist period followed by a 60-90 day cold, moist period.
F	These seeds need a 60-90 day cold, moist period followed by a 60-90 day warm, moist period followed by a 2nd cold, 60-90 day moist period.
G	Highest germination rate in cool soil.
H	Seeds need scarification: One way this can be achieved is to rub the seed between two sheets of sand paper. If code "C" is also called for, scarify first.
I	Legume Inoculant (more info next year).
J	Legume seeds (more info next year).
K	Parasitic species which needs a host plant.
L	Plant fresh seed or keep seed moist.
M	Best results when seed sown outdoors in the fall for a natural winter.
