HOW TO GROW

Sowing: Direct sow in late fall, planting just below the surface of the soil. For spring planting, mix the 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 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 seeds from the stems by rubbing them lightly. Store the cleaned seed in a dry, cool place.

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.

DESCRIPTION

IN-STOCK ORDERS SHIP THE NEXT BUSINESS DAY VIA THE US POST OFFICE.

Named for its distinctive wiry green foliage, this native plant also sports sunny yellow flowers. This ornamental plant can be used for an herbal tea, but we prefer to use it as a pretty wildflower.
Though a beautiful ornamental plant, this native species is most well known for its use in a type of herbal tea. Native American tribes throughout the American southwest harvest its stems just as the buds open, then bundle the dried stems for use in brewing a healing beverage. The genus name "Thelesperma" comes from a Greek word referring to the shape of the seed, while the species name "filifolium" means "thread-leaved" in reference to the delicate foliage.
