  • circleLife cycle

    The Hosta 'Smiling Mouse' life cycle starts with seed germination, which occurs in moist, well-draining soil with some shade. Following germination, seedlings emerge and develop into juvenile plants, establishing a root system and foliage through photosynthesis. As the plant matures, it enters a vegetative stage in which it produces large, heart-shaped leaves that are variegated with a hallmark ripple effect along the margins. Over time, the Hosta 'Smiling Mouse' may produce lavender flowers atop tall stalks during the summer months, which is its reproductive phase and can attract pollinators like bees. After flowering and potential seed production, the plant enters a period of dormancy during the colder months, with leaves dying back to ground level. Come spring, the Hosta 'Smiling Mouse' re-emerges from the rootstock to continue its life cycle anew.

      Spring-Early Summer

    • For the Hosta 'Smiling Mouse', the most popular method of propagation is division. This is typically done in late summer to early fall, or in spring as the Hosta is emerging from dormancy. To propagate by division, gently lift the entire Hosta clump from the ground and clear away any excess soil. Using a sharp knife or spade, carefully split the clump into smaller sections, ensuring that each section has at least two or three shoots and an adequate amount of roots. Replant these divisions immediately in prepared soil, maintaining the same planting depth as the original plant. Water the newly planted divisions thoroughly to help establish them. This method allows gardeners to create new plants that are genetically identical to the parent, ensuring the unique characteristics of the 'Smiling Mouse' Hosta are preserved.
