Hosta (Tardiana Group) 'Halcyon' (Plantain lily)
Hosta (Tardiana Group) ‘Halcyon’ is prized for its thick, blue‑grey leaves that form a tidy mound in shaded borders. In summer, slender stems carry soft purple, bell‑shaped flowers that add a gentle lift above the foliage without stealing the show.
Plant in fertile, moisture‑retentive soil that drains well. Partial shade is best, though it will tolerate some sun if the ground stays evenly moist. It’s ideal under shrubs, along shady paths, or as a calming foil to brighter, variegated hostas and woodland perennials.
Set plants at the same depth as they were growing and water well while they establish. Mulch in spring to keep roots cool, feed the soil and reduce watering. In autumn, let foliage die back naturally, then clear away old leaves before new shoots emerge in spring.
‘Halcyon’ brings dependable structure and colour contrast: pair it with ferns, bleeding hearts and astrantias, or use it to edge a border where you want a clean, repeating rhythm. The flowers can also be enjoyed as simple, understated cut stems indoors.
You’ll receive one plant in the stated grade, dispatched in season for planting. With steady moisture and a little patience, it will bulk up into a long‑lived clump that returns reliably year after year.
