Thymophylla tenuiloba, The Dahlberg Daisy
A tiny annual plant that goes by this big name is one of the plants that I like to use every year. It make a fine fringe along a path or a lacy spill of golden flowers in a container. Nothing is better for a Fairy Garden, and it even pops up between the flagstones, occasionally proving hardy enough for this Ohio zone 5 climate.
3 Important Things To Know About Dahlberg Daisies
- Native to Texas, hardy in Zone 11; grown as an annual elsewhere.
- Can self-seed, although not reliably in Ohio
- Late to bloom unless started indoors early in the season.
Easy to grow
Their leaves are so finely divided that they resemble green thread. Some say they are fragrant, but I didn’t find the scent noticeable.
This is one of those plants of “many names” aka Dyssodia tenuiloba, and commonly called Dahlberg daisy or Golden fleece.
It grows to about 10 or 12 inches high and wide. The seedheads are miniscule little brown broom looking sorts of things, easily removed. If not kept watered (although Thymophylla tenuiloba is a drought tolerant plant), it will start to go to seed quickly. Just trim them off and keep it watered better to provide a new wave of bloom.
The Dahlberg daisies bloom long into the fall, much like the Calendulas. Especially when they are grown in the midst of stones or sheltered by other plants. Eventually they succumb to frost, but not without a cheery last hurrah.
How Thymophylla Tenuiloba Is Grown
Good growing practices:
- Dry to medium soil is fine, likes moisture,but need good drainage.
- Sunny to partly shady.
- Surface sow seed, needs light to germinate.
Starting Dahlberg Daisies From Seed Indoors
Sow seeds indoors 8 to 10 weeks before last frost, press seeds into the soil surface lightly. Keep moist until they germinate. Once the daisy plants develop two sets of their true leaves you can transplant them where they are to grow.
Starting Dahlberg Daisies Outdoors
Sow outside in prepared soil after all frost danger is past, or plant transplant seedlings at that time.
*When available in garden centers and nurseries, I find this plant is snapped up quickly, probably because those tiny little flowers are so hard to resist.
Native to south central Texas and northern Mexico, this is a prairie plant.
Perfect for garden containers, pretty along walkways, good for the front of borders. Small stature and diminutive in all its parts makes Dahlberg daiies very nice for Fairy Gardens. Excellent in Cottage gardens, and -as a native plant- good for prairie or New American garden beds. Cheerful and easy for Children’s gardens.
A good plant for hot, south-facing slopes, and tucks nicely into a rock garden.
Thymophylla tenuiloba can be used as ground cover, with 5000 seeds covering 100 square feet.
Thymophylla refers to “thyme-like” foliage and the plant was once named “Dyssodia”, a group of daisy-flowered plants, and Hymenatherum tenuilobum.Prairie plants
