How to plant, grow and care for lamb's ear, Stachys byzantina
Lamb's ear (Stachys byzantina) is a drought-tolerant perennial with silvery green, evergreen leaves that are covered in a fine coating of hairs, that makes them appear woolly. In summer it bears spikes of pink-purple flowers. It's a popular choice for dry gardens, gravel gardens and rock gardens, and is also loved by the wool carder bee, a solitary bee that 'cards' the hairs from the leaves to make a soft nesting chamber into which she lays her eggs. You may spot male wool carder bees patrolling patches of lambs' ear which they have claimed as their territory, and fighting off rivals and even bumblebees who venture too close.

Propagating lamb's ear
Lamb's ear can be propagated from seed but it's easier to propagate by division in spring or autumn. Simply dig up the rootball and use a sharp spade or knife to divide it into two or three parts, ensuring a good section of roots is contained in all pieces, and replant them separately. Water thoroughly for the first couple of weeks, until each plant has established.
Growing lamb's ear: pests and problem-solving
Lamb's ear suffers from no pests or diseases. However, in damp soils or after heavy rain or too much water, the leaves can appear to 'wilt' and rot. Remove wilting or rotting leaves as soon as you see them, to stop the rot spreading to the rest of the plant, and reduce watering if you can. If drainage is an issue, you can dig up the plant and place a thick layer of grit at the bottom of the planting hole to aid drainage, while adding a layer of gravel beneath the leaves can reduce contact with the soil and help prevent future rotting.
