How to keep Antennaria Howellii.
Light
Howell's pussytoes is a perennial herbaceous plant that prefers sunny conditions and is native to open habitats, often occurring in meadows and grasslands. It favors full sun but can also tolerate partial sun.
Water
Howell's pussytoes thrive in moderately moist environments, benefiting from weekly watering to support its drought-resistant qualities. As a perennial herbaceous plant, it is best grown outdoors to take advantage of natural rainfall, which promotes optimal health and vigor.
Temperature
Howell's pussytoes can adapt to a wide range of temperatures, but its distribution may still be restricted by different combinations of moisture and heat. It performs best in warm summer climates with sufficient rainfall or watering. Extended periods of cloudy, rainy weather, as well as prolonged high temperatures, can increase the chance of Howell's pussytoes dying. In winter, proper protection from cold can boost the plant's survival rate.

Although Howell's pussytoes has fairly low fertilizer requirements, applying fertilizer once a year can improve its survival and encourage healthier, longer-lasting blooms.
Pruning
For optimal growth, Howell's pussytoes benefit from pruning dead or damaged leaves in early to late spring. Avoid heavy pruning and emphasize light, regular maintenance instead. This tidying helps enhance air circulation, reduces the risk of disease, and keeps the plant looking attractive.
