Hosta tardiva aka Late Blooming Hosta

Hosta tardiva is a perennial in the asparagus family, Asparagaceae. Its native range covers south-central and southern Japan. Kew places it within the temperate climate zone. Plants For A Future records its habitat as fairly dry, open ground. This habitat record describes where it grows in the wild. The same source lists several settings for garden use. These include woodland edges, sunny margins, and sites with dappled shade. It also lists the plant for food forest gardens. The RHS records it as not native to Britain or Ireland.

Plants For A Future describes two ways to raise this species. Gardeners can grow it from seed or divide existing plants. Sow seeds in spring in a greenhouse with light shade. Cover them with only a thin layer of compost. Keep the compost moist while waiting for seedlings to emerge. At 50°F, or 10°C, germination takes one to three months. This means seedlings may not all appear soon after sowing. Move each seedling into its own pot once large enough to handle.

Keep these young plants in the greenhouse through their first winter. Set them in their final sites in late spring or early summer. Wait until the last expected frost has passed before planting out. Division offers another way to produce more plants. Plants For A Future allows division through much of the year. That timing depends on having enough moisture in the soil. It favors March, when growth starts, or early autumn. For autumn division, the soil should not be too dry. Plants can also stay in place for years without division.

Plants For A Future gives this species a modest food rating. It scores its edible value at two out of five. The leaves and stems are the parts listed for cooking. The source describes cooked use, rather than use as raw greens. It reports no known hazards, but gives no separate pet-safety assessment. It lists no known medicinal use and rates that value zero. Other uses also receive a zero rating in that database. Its record does not flag the plant as a weed risk. These ratings describe the source's recorded uses, not a complete safety review.
