Cerulea (Blue Lotus of the Nile) annual water lily
Also known as Egyptian Blue Lotus, Sacred Blue Lily of the Nile
A Plant with History and Beauty
For millennia, the Cerulea Water lily has captured imaginations—enjoyed in ancient Egyptian temples, the Pharos to the people of Egypt, and today’s backyard ponds. Its light-blue, star-shaped flowers rise gracefully above the water, set against glossy green pads. Unlike true lotuses, the Cerulea is a tropical waterlily—ideal for adding exotic color and elegance to your pond all summer long. Cerulea flowers have a unique element from other water lilies; it is
This is more than just a pretty flower. The Cerulea helps shade your pond, reducing string algae and green water naturally, without chemicals. Its surface cover provides shelter for fish and a haven for dragonflies and pollinators. With regular care, it rewards you with blooms almost daily in warm weather.
The Sacred Blue Lotus of the Nile
Imagine drifting down the Nile River thousands of years ago, the hot Egyptian sun shimmering across the water. Along the riverbanks, a flower rises with poise and mystery—its petals gently opening with the day’s first light. This was no ordinary plant to the ancient Egyptians. To them, it was sacred. The water lily symbolized rebirth, vitality, and—most intriguingly—love.
Priests offered it in ceremonies. Artists carved its likeness into temple walls. Pharaohs adorned themselves with its fragrance at banquets. But behind the beauty and symbolism, there was another secret: the plant was believed to stir desire, to awaken passion, and to heighten vitality. In fact, the water lily’s reputation as an aphrodisiac was so strong that it became part of ancient love rituals, admired for both its elegance and its intoxicating effects.
Owning one today isn’t just about planting a flower in your pond—it’s about bringing home a living connection to history, a bloom once held in the hands of kings and queens, carrying with it centuries of reverence, allure, and whispered mystery.

Key Benefits of Cerulea, Blue Lotus of the Nile water lily
-
🌸 Cerulea has striking, very light-blue, stellate blooms held high above the surface. Truly a water lily, but it was historically known as a lotus before the advent of modern plant classification. A true lotus in plant classification is a nelumbo which is very different, grows in shallow water and stands high above water with hydrophobic leaves. No true lotus (Nelumbo are blue or purple), which now causes confusion, because lotus and lily were used interchangeably before plant classification, the common name has stuck with this plant.

Planting & Care
-
Choose Soil: Plant in true loam topsoil (never potting mix, peat, or compost). If you don’t have access to loam, we recommend PondGro Aquatic Soil.
-
Select Pot: Use a wide, shallow container (3–7 gallon). Wider pots allow horizontal rhizome growth and larger spread.
-
Fertilize: Push 5–6 fertilizer tablets deep into the soil on the 1st and 15th of each month during the growing season.
-
Place in Pond: Submerge so the crown sits 6–18 inches below the water’s surface. Avoid strong splashing from waterfalls.
-
Sunlight: Provide full, direct sunlight all day. This plant will not thrive in shade.
-
Overwintering: Treat as an annual in most of the U.S. Only in Zone 8a and warmer may it survive in shallow, sunny ponds outdoors. Otherwise, replace each spring.
Common Questions
Is this the same as a true lotus?
No. Despite its nickname “Blue Lotus,” this is a tropical waterlily, not a Nelumbo (true lotus). There are no blue Nelumbo, but this has been called a lotus for over a thousand years before there was scientific plant classification, and the common name has stuck.
Will it bloom daily?
Yes! In warm weather with full sun and regular fertilizer, blooms appear almost daily. Tropical water lilies typically produce one to three blooms per day when fertilized daily throughout the summer and kept in full, direct sunlight with adequate space. One plant can typically produce 90-210 flowers per season under good growing conditions.
How wide will it spread?
Small tropicals reach about 2–3 feet across. Medium and large varieties can spread 4–8 feet wide in a single season—and even more in larger pots with extra fertilizer.
Can I grow this indoors or in shade?
No. Cerulea needs direct, outdoor sunlight all day to flower and thrive.
Can koi live with Cerulea?
Yes, though you may need to protect tender shoots from nibbling until the plant is established. We suggest that if you wish to try water lilies with koi, plant them initially in a tank or other body of water in the sun, potted all the same away from the koi for 4-5 weeks to become vigorous and grab their new soil well with new, stronger roots to prevent the lilies from being uprooted. Do not cover in stone, this causes mortality too often and prevents new growth from the lily.
What’s the best soil?
Always use loam or PondGro Aquatic Soil. Never use bagged potting soil, calcined clay alone, or pea gravel.
How do I overwinter?
In Zones 8b and lower, it cannot overwinter outdoors. Enjoy it as a summer annual and replant next spring.
