Cardinal Flower Seeds binF11

Lobelia Cardinalis Seeds! These seeds are tiny!

These TINY seeds produce a plant that is easily grown in rich, medium to wet soils in full sun to part shade. Needs constant moisture. Tolerates brief flooding. Soils should never be allowed to dry out. Tolerates full sun in northern climates, but appreciates part afternoon shade in hot summer climates of the lower Midwest and South. Root mulch should be applied in cold winter climates such as St. Louis to protect the root system and to prevent root heaving. Mulch will also help retain soil moisture.

Direct sow in late fall, planting on the surface of the soil since these seeds need light to germinate. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before planting. To start indoors, sow the seed 6-8 weeks before the last frost of spring and keep the soil lightly moist until germination. Transplant the seedlings as soon as they can safely be handled and there is no chance of frost
