Astilbe 'Ice cream' 50 Seeds

Plant in part shade to full shade. Morning sun with deep afternoon shade is ideal for vibrant flower colors.

Provide rich, organic, moisture-retentive soil. Amend the planting site heavily with compost or peat moss.

Keep the soil wet but never waterlogged, which can suffocate the roots.

Water deeply and never let the soil dry out. Astilbes are not drought-tolerant; dry soil causes immediate leaf crisping and browning.

Apply a 2- to 3-inch layer of organic mulch (like shredded bark or leaf mold) to retain soil moisture and keep roots cool.
