Now, you might be wondering, is lamb’s ear invasive?

Lamb’s ear plant is generally not considered invasive. It is a well-behaved perennial plant that does not aggressively spread or take over other plants. 

However, it is always a good idea to monitor its growth and prevent it from self-seeding excessively.

Growing Lamb’s Ear

Lamb’s ears are easy-to-grow herbs that provide ideal ground cover. There are several cultivars of this herbaceous perennial in the mint family (Lamiaceae) native to the Middle East that offer unique characteristics. 

Warm soil temperature aids germination, so place the seeded tray or pots on a heating mat or a warm space, such as the top of the refrigerator or a table above a heat vent. 

Harden off the seedlings before planting them outdoors. Spring is the best time to set out plants so they can become established during cooler weather.  

This herbaceous plant is evergreen in mild climates. In colder areas, the leaves will die back to the ground during harsh winters and reemerge in the early spring.

Lamb’s Ears plants are drought-resistant, self-seeding, and highly resilient. Avoid watering the top of the new plants; the leaves will rot or develop fungal leaf spots or powdery mildew if they get too wet.  

The only unforeseen circumstances are root rot, pests, or other fungal diseases that might take hold if you leave the dying foliage to rot.

This perennial thrives in poor soil that is well-drained and has a slightly acidic pH. You can skip giving your lamb’s ear fertilizer in most situations since it prefers soil that is not rich.  

Avoid overwatering as wet leaves invite disease, as do high humidity summers. 

From midsummer, these tough native plants bloom their golden heads off in sun or light shade and mix well with other perennials, annuals, and shrubs.  

In desert areas and high-heat locations, it can profit from partial shade. Excessive heat and dry conditions will cause the fuzzy leaves to scorch. Leaving dead leaves and growth puts the plant at more risk of pests and disease. 

However, it is prone to fungal disease due to its sensitivity to humid conditions and poorly draining soil. In the humid months of summer, it can develop rot and leaf spots, even if the soil is well-draining.  

Diseased foliage can sometimes attract sowbugs, not insects but woodlouse, land crustaceans that feed on fungi and bacteria on dead and rotting vegetation. 

They are considered invasive, often growing back even when pulled out. Because of this, some people often consider it a weed.

They are grown in flowerbeds and borders in USDA hardiness zones 4 through 8.
