It was never an AHGA Hosta of the Year, so there is no second AHS size. Registered sizes are registration data, not a promise of garden size.
Where it fits
An upright plant registered at 36 in across and 36 in high, with scapes recorded at twice that height. The registry does not give bloom dates, so we cannot say when those scapes appear.
How it compares
- 'Regal Splendor' is its sport: frosty blue leaves with a creamy yellow margin in spring, changing to a creamy white margin on a dark green center by mid-summer (booklet). Registered at 40 in across and 38 in high; the booklet gives 30 × 70 in.
- 'Sagae' is also upright (booklet) with yellow-to-cream margins and wider leaves (12.5 × 9.5 in registered).
- 'Halcyon' is a medium blue that the booklet calls mounding, with much smaller, pointed leaves (4 × 3 in registered).

Limits and unknowns
The registry entry gives no growth rate, leaf texture or bloom dates, and none of the AHS sources we checked says how it copes with slugs or bright light. General planting advice is in our hosta care guide.
