Lamb’s Ear

The leaves and stems of lamb’s ear, also known as betony, are covered with a dense layer of tiny white hairs that make them feel silky to the touch and give them a silvery appearance. This plant is a must for sensory garden settings and is sure to delight children who are encouraged to stroke the soft leaves. While lamb’s ear is most commonly grown for its foliage, it does bloom; some varieties are grown specifically for their prolific blooms.

In addition to lamb’s ear plants providing tactile joy, the silvery foliage also serves as the perfect backdrop for many other plants. The flower stalks are usually 12-24 inches tall, with small purple, white, red, or pink blooms.

Lamb’s ear is a vigorous grower. It isn’t on the USDA invasive plant list, but unless it is carefully contained, it can become troublesome. Lamb’s ear produces creeping stems that root along the soil, creating dense mats of foliage. The roots aren’t thick, so the plants can be pulled up where you don’t want them. This spreading habit makes lamb’s ear a good choice for a groundcover in full sun or poor soil situations. Lamb’s ear also readily reseeds itself, so removing the flower stalks before they go to seed reduces spreading.

Lamb’s Ear Care Tips

Light

This plant performs best in full-sun conditions, but it can withstand shade. The plant looks greener in the shade because it produces fewer dense hairs.

Soil and Water

Lamb’s ear varieties withstand poor soil conditions and drought. One thing it does not tolerate, however, is soggy soil.

Give the plant about 1 inch of water weekly if the soil is dry. Don’t water from the top of the plant. Keep the plant as dry as possible by watering it from the bottom.

Temperature and Humidity

The soft hairs on the leaves and stems help prevent plant moisture loss, making it exceptionally drought-tolerant. Heat is not a problem for lamb’s ear. However, in desert locations, it is best to select a planting location with at least some partial shade. Low humidity is best for this plant. In locations with high humidity, the plant is susceptible to leaf rot.

Fertilizer

Lamb’s ear doesn’t like rich soil. It is best to avoid giving the plant any fertilizer.

Pruning

Because the prolific seeds spread quickly, deadhead the flower stalks or cut them back to the ground to prevent unintended spread. Prune any dead or damaged leaves as they occur. Repeat the process whenever you see more dead leaves or about twice a year. The plant can stand a harsh pruning if needed. It’s difficult to kill.
