How to keep Onosma Tricerosperma.
Light
Onosma tricerosperma is a sun-loving perennial herbaceous plant native to open habitats, commonly found in meadows and grasslands. It prefers full sun but can also tolerate partial sun.
Temperature
Onosma tricerosperma can tolerate a broad range of temperatures, although its distribution may still be restricted by different combinations of moisture and heat. It performs best in warm summer conditions with sufficient rainfall or watering. Extended stretches of cloudy, rainy weather, as well as prolonged high temperatures, can raise the likelihood of Onosma tricerosperma dying.

Fertilizer
One spring application of fertilizer is generally adequate for Onosma tricerosperma, though multiple feedings can optimize growth. Fertilize every one to one and a half months.
