Gloriosa Daisy seeds must be stratified before planting otherwise germination will not occur.

After 30 days, you can immediately use the seed since it is ready for the opportunity to germinate

Sow seeds in a seed-starting soil formula in cell trays or small pots 1 to 2 weeks before your last local spring frost.
Firmly press seeds just into the soil surface but do not cover with soil as they need some light to germinate.
Keep the soil moist and between 70-75ºF.
Germination will occur in about 20 days.
As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow 3 inches beneath fluorescent plant lights turned on 16 hours, off 8 hours, raising the lights as the plants grow taller.
Before transplanting outdoors, harden off seedlings for several days. Do this by taking them outside during the day and bringing them in at night (Outside temps should be above 50°F when you start this process)
In mild climates, seeds may be direct sown any time of the year after you have stratified the seeds.
Direct sow in a warm, sunny location with well-draining soil.
Broadcast seeds evenly and press just into the soil surface but do not cover with soil as they need some light to germinate.
Keep the soil moist until germination occurs which will generally happen in 16 to 22 days, depending on soil temperature and moisture.
Once seedlings emerge, thin out so each plant is spaced 14 to 18 inches apart.
Water seedlings regularly until they become thoroughly established.
This plant grows very quickly and needs little care. Though this plant grows well in fairly dry soil, it performs best with occasional watering in dry weather.
Blooming may occur in its second year of growth depending on your climate.
Mature plants tolerate heat and drought well, as well as tolerating clay or rocky soils.
Deadhead for the longest blooming period.
Mature plants can be divided.
When harvesting Gloriosa Daisies for cut flowers, choose stems with fully open blooms.
Use sharp scissors or pruning shears to make clean cuts at a 45-degree angle just above a leaf node.
Harvest early in the morning or late in the evening when the flowers are hydrated and less stressed.
Place cut stems immediately in a bucket of lukewarm water to prevent wilting.
Remove any leaves that will be below the water line in your vase to prevent bacterial growth.
Arrange the cut flowers in a vase filled with fresh water and display them in a cool location away from direct sunlight and drafts for maximum longevity.
