Fay McDonald Waterlily – Jewel-Toned ISG Blooms 

The Fay McDonald Waterlily is an extraordinary intersubgeneric (ISG) hybrid, bred by award-winning hybridizer Mike Giles. This stunning hardy × tropical cross dazzles with flowers in cool blue to deep purple jewel tones, accented by amber centers and lighter petal bases. Its foliage emerges bronze and matures to green, offering a striking contrast to the regal blooms.

Compact in spread yet prolific in blooming, Fay McDonald is a must-have for collectors and pond enthusiasts seeking something unique. Established plants produce large flowers, 6–9 inches across, held elegantly above the water’s surface on sturdy stems.

Special Planting & Shipping Conditions

• Later Spring Shipping: As an ISG, Fay McDonald waterlily emerges later in the season than standard hardy lilies. Orders ship only when water temperatures are consistently warm (≥70°F at root level).

• Patience Pays Off: If purchased with other plants, expect your entire order to wait until Fay McDonald is ready. For earlier shipping of other pond plants, place separate orders.

• Dormancy Considerations: Planting too early in cold water may cause dormancy. Always wait for warm water to ensure strong growth.

Do’s and Don’ts

✅ Do:

• Plant Fay McDonald in full sun with warm water.

• Use a wide container with heavy loam soil for best root establishment.

• Fertilize generously for continuous blooms.

• Divide regularly to maintain strong flowering.

❌ Don’t:

• Don’t plant in cold water or too early in spring — ISGs require warmth to break dormancy.

• Don’t overcrowd with floating plants or other lilies; Fay McDonald needs space and full sunlight on its pads for optimal flowering.

• Don’t cover the crown or rhizome with stones — this hinders growth and can kill the plant.

• Don’t delay planting after arrival — pot immediately and place in the pond.
