Planting Hosta Sieboldiana 'Elegans' from seeds. Here's a general guide: 1. Seed Stratification: Hosta seeds often benefit from a period of cold stratification to break dormancy and improve germination rates. Place the cleaned seeds in a damp paper towel, seal them in a plastic bag, and refrigerate them for 4-6 weeks. 2. Soil Preparation: Fill small pots or seed trays with a well-draining potting mix. Hostas prefer rich soil with good moist retention. 3. Sowing Seeds: Sow the stratified Hosta seeds on the surface of the soil in the pots or trays. Press them gently into the soil, but do not cover them, as they require light to germinate. 4. Watering: Water the soil lightly after planting to ensure it is evenly moist. Avoid overwatering. 5. Germination: Place the pots or trays in a cool location with indirect sunlight. Hosta seeds typically germinate best at temperatures around 65-75°F (18-24°C). Germination may take several weeks to months. 6. Transplanting: Once the Hosta seedlings have developed several sets of true leaves and are large enough to handle, transplant them into individual pots filled with potting mix. Harden off the seedlings by gradually exposing them to outdoor conditions over the course of a week before transplanting them into the garden. 7. Outdoor Planting: Choose a shaded or partially shaded location in the garden for planting Hosta Sieboldiana 'Elegans.' Prepare the soil by amending it with matter to improve moist retention. Space the transplanted seedlings according to their mature size, typically 18-24 inches apart. 8. Care: Keep the soil consistently moist but not waterlogged during the growing season. Mulch around the base of the plants to help retain moist.
