🌸 Meet the Stunning Wanvisa Lily! 🌸
If you’re looking to add a burst of color to your pond or water garden, the Wanvisa water lily is a showstopper you don’t want to miss. With its unique blend of pink, peach, and yellow mottled petals, each bloom looks like a work of art — no two are exactly alike!

🪷 Why We Love Wanvisa:
✅ Hardy & easy to grow
✅ Blooms prolifically from late spring through summer
✅ Gorgeous contrast of speckled petals and deep green lily pads
✅ Award-winning (IWGS Best New Water Lily 2010!)

🌿 Care Tips:

Sunlight: Full sun (6+ hours a day for best blooms)

Water Depth: 12–24 inches above the crown

Container: Best grown in a wide, shallow pot with heavy loam soil

Fertilizing: Use aquatic fertilizer tablets monthly during growing season

Wintering: Hardy in zones 3–10 — just sink the pot to the bottom of the pond in colder months

Perfect for ponds, container water gardens, or even patio tubs! The Wanvisa lily brings vibrant energy and tranquility wherever it grows. 🌞💧
