HOW TO GROW
Sowing: Direct sow in late fall, planting just below the surface of the soil. For spring planting, mix the Thelesperma Filifolium seeds with moist sand and store in the refrigerator for 30 days before planting. Keep the soil lightly moist until germination.
Growing: Water seedlings occasionally until they become established; since they need good drainage, mature plants grow well in drought and poor soil as well as rocky soil or gravel. Occasional watering in especially dry weather will improve its blooming. This greenthread plant will self-seed occasionally in good growing conditions. It makes an excellent choice for rock gardens, and attracts butterflies.
Harvesting: For cut flowers, choose stems with flowers that have just opened. Strip the foliage that will fall below the water level, and place in water immediately.
Seed Saving: After the flower petals fall from the head, the center cone will begin to develop seed. Remove the seed heads as soon as the stem beneath the cone begins to turn dry and brown. Spread the seed heads out to dry away from direct sunlight, then separate the Thelesperma Filifolium seeds from the stems by rubbing them lightly. Store the cleaned greenthread seed in a dry, cool place.

Greenthread seeds
I purchased these seeds for my brother. It is passed our planting season. Will have to wait until spring to see how these will grow for him.
Good germination, unfortuneate annotation
In moist potting soil at about 75 degrees F, I got around 50% germination within 48 hours. Unfortuneately the packet had a religious annotation which you may find offensive if you don't hold the same religious beliefs as the vendor. It will make it difficult for me to buy from them again.
Growing Greenthread in the UK
I have been growing Greenthread tea / Navajo Tea for the last 6 years.
The seeds are germinate, it is a fast grower and makes a great tea that I find helps with my auto immune liver disease .
So pleased Everwilde have been able to supply quality seeds
Grows almost too well in central TX
Even without supplemental water, these things will thrive to the point where they shade out other wildflowers, especially seedlings. So far mine have survived a 26 degree (F) freeze and are perennial, and I've had to thin them significantly. I'm in the middle of zone 8.
But for tough growing spots and a mass of yellow color almost year round once established, they're great.
