Hybrid Lilies & Their Parentage: A Genetic Guide

Lily hybridization has exploded — new colors, forms, "impossible crosses" setting seed. Names sometimes reveal lineage, sometimes obscure it.

Key Hybrid Groups & Parents

• L. sulphurgale: L. sulphureum × L. regale
• L. marhan: L. martagon × L. hansoni
• Princeps, Shelburne, Creelman, Crow's, Green Mountain: All carry L. regale blood
• Centifolium Hybrids: L. leucanthum var. centifolium × Creelman, sergeantme, browni, regale
• Havemeyer Hybrids: L. myriophyllum × L. henryi → Aurelian-like, yellow trumpets
• Backhouse Hybrids: L. martagon × L. hansoni → small blooms, ivory-gold-pink-mauve-orange
• Preston Hybrids (Stenographer Series): L. dauricum pollen on L. davidii var. willmottiae → brilliant, hardy
• Rainbow Hybrids: L. umbellatum × L. elegans → straw-yellow to deep gold, orange, red
• Fireking: L. umbellatum × L. willcrovidi (complex ancestry) → vermilion-scarlet, purple spots
• Mid-Century Lilies: L. tigrinum × L. umbellatum → unstaked, 2–5 ft, tiger-pink over copper/gold/red
• Golden Chalice: Dwarf, early, cup-shaped, lemon-gold-apricot
• Fiesta Hybrids: Martagon-type, 4–6 ft, bell-shaped pendants, yellow through maroon
• Hollywood Hybrids: L. concolor × large cup species → tall uprights, film star names

Variability Is Normal

Seedlings from same cross differ — throat color, petal shape, bloom time. Graceful stem distribution beats L. regale's "cartwheel."
