| General Description | Classified as a D1 Y - Y (Trumpet, Long-Cupped). |
| Landscape | Massing and naturalization. |
| Propagation | About every five years or as the number of blooms decrease lift clumps with a fork after the foliage has withered. Pull the bulbs apart and detach any offsets, replant bulbs three times their own depth (15 cm) and depending on plant size 3-10 cm apart. Plant bulbs in full sun to partial shade in autumn in clumps or large groups for best affect. Suited to naturalization in woodland gardens and turf. Interplant where dying bulb foliage may be hidden by later blooming perennials or if planted in turf let foliage yellow before mowing. |
