You can propagate from seeds but some cultivars and hybrids like ‘Helen von Stein’ do not grow from seeds. This is because when different species are bred with each other, they won’t be able to self-seed. If you try to grow them from seeds they might not grow or not like the parent plant. But, you can propagate these cultivars with nursery plants or by division.

When To Plant

Ideally, spring is the best time to plant lamb’s ear, so that it gets established during cooler weather. When propagating from seeds, start planting six to eight weeks before the last frost date; they can take up to a month to germinate. Once frost gets over, transplant it in the garden or relocate the pot outdoors for full sun.

Where To Plant

You can plant lamb’s ear in the garden bed, garden borders, or in the container. Plant where it gets full sun to part shade and good drainage. In the garden, plant where water does not get stuck for too long. Soggy soil will damage its roots, leading to improper growth due to diseases like root rot.

Do not grow them as a specimen plant. Use as a rambling ground plant or for soft edging. As an edger, keep them inside the boundary, they look striking with silver leaves and purple flowering. Besides spreading by roots, the flowering lamb’s ear variety can also spread through self-seeding, but you can control that by deadheading flowers stalks. 

Propagating Lamb’s Ear

They can be propagated from seeds, cuttings, and division. However, the best and easiest way to propagate them is from division. You can divide a mature plant into 3 to 4 parts to grow individually in different locations. Below are steps to divide:

  • Take a gardening shovel, dip up the mature plant with its roots. plant should be at least 5-6 inches taller in height.
  • Shake soil from roots and locate its root ball.
  • Cut the roots attached with leaves in different sections with the help of a gardening shear.
  • Plant these cutting in good soil and sunny area.
  • Water to keep soil moist.
