Victoria cruziana
Santa Cruz water-lily
Description
Source: leafsnapVictoria cruziana (Santa Cruz water lily, water platter, yrupe, synonym Victoria argentina Burmeist.) is a tropical species of flowering plant, of the Nymphaeaceae family of water lilies native to South America, primarily Bolivia, Argentina and Paraguay. The plant is a popular water garden plant in botanical gardens where its very large leaves can reach their fullest, up to 2 m wide with a thick rim up to 20 cm high. although rims up to nine inches (23 centimeters) have been recorded. It can be grown in cooler waters than its sister within the genus, the more familiar giant waterlily, Victoria amazonica. A 25 cm diameter flower blooms for two days, arising from the underwater bud, as a white flower that turns to a deep pink on the second and final day of its bloom. V. cruziana is a thermogenetic or heat-producing plant. The plant prefers to live in colder non moving water and requires warm temperatures in order for the flower to blossom, hence the plant must distribute a lot of energy to keep itself warmer than its natural environment (above 90 degrees Fahrenheit). The floral stigma are attached to a cup that is protected by spines, and the floral cup begins heating up in the bud, then, as the flower opens, it releases a strong sweet scent to attract pollinating beetles, then continues to provide heat to the flower while the beetles are pollinating.Victoria cruziana was discovered in Bolivia on one of many expeditions through the country by Alcide d'Orbigny whose presence was sponsored by Andrés de Santa Cruz. The first collected specimens were returned to France where they were named in honor of Santa Cruz by Alcide's brother, Charles Henry Dessalines d'Orbigny.
Care Guide
💧 Water
Originating from South America, the Santa Cruz water lily thrives in humid, tropical conditions. It prefers stable moisture levels without being completely submerged. To maintain its vitality, it should be watered weekly. Primarily an outdoor aquatic plant, the Santa Cruz water lily flourishes when it receives the right balance of water temperature and light, which are essential for its night-blooming flowers.
How should I water my Santa Cruz waterlily?
To ensure the health of your Santa Cruz waterlily, here are some tips for watering it: 1. Use filtered water that is at room temperature. Tap water may contain harmful particles, so filtering the water is better for the plant. 2. The water should be at room temperature or slightly warmer. This is because the Santa Cruz waterlily is accustomed to warm environments, and cold water can shock its system. 3. Avoid overhead watering. Instead, focus on applying the filtered room temperature water directly to the soil until it is fully soaked. Overhead watering can lead to issues with the foliage. 4. Soaking the soil is beneficial for the plant. It helps to moisten the roots and supports their growth and nutrient absorption in the soil.
What should I do if I give my Santa Cruz waterlily too much or too little water?
Overwatering is a more common issue than underwatering when it comes to the health of your Santa Cruz waterlily. When the plant gets too much water, its stems and leaves may wilt and turn yellow. Over time, this can lead to diseases such as root rot, mold, and mildew, which can be fatal for the plant. While underwatering is less common, it can happen, and you'll notice brittle and brown leaves if it does. It's important to notice the signs of overwatering early on. Some diseases, like root rot, may not be fixable if left too long. If you see signs of overwatering, reduce your watering schedule and check the soil drainage. If the soil drains poorly, replace it with a well-draining potting mix. If your waterlily needs more water, simply increase your watering frequency until the signs improve.
How frequently do I need to water my Santa cruz waterlily?
If your Santa cruz waterlily is in a pot, you can determine if it needs water by sticking your finger into the soil. If the top two to three inches of soil feel dry, it's time to water it. If you're growing your Santa cruz waterlily in the ground, you can use a similar method to test the soil. Once the top few inches of soil have dried out, it's time to water it. Typically, during spring and early fall, watering once a week is sufficient. However, in extremely hot weather, you may need to water it twice or more per week. It's worth noting that mature, well-established Santa cruz waterlilies can tolerate drought quite well.
How much water does my waterlily from Santa Cruz need?
When watering your Santa cruz waterlily, don't be afraid to give it a generous amount of water. Wait for the top two to three inches of soil to be dry, then give the plant a thorough watering. Make sure to water enough to completely soak the soil. If there is excess water draining out of the pot's drainage holes, you've watered it enough. If you don't see any excess water draining, you may have not given it enough water. However, be careful not to let the water accumulate in the soil, as this can harm the plant. It's also important to ensure the pot has well-draining soil to avoid water pooling. If the plant is outside, it generally needs about 1 inch of rain per week.
How should I water my Santa cruz waterlily as it grows?
The water needs of the Santa cruz waterlily change depending on its growth stages. When the waterlily is young or has just been transplanted, it requires more water. This is because during these stages, the waterlily focuses on developing new roots for future growth, which require more moisture. However, as the waterlily matures, it will require less water. Another stage where more water may be needed is during the bloom period, as flower development requires a significant amount of moisture.
☀️ Light Full sun
Santa cruz waterlily prefers locations that receive abundant sunlight throughout the day. This supports the plant's healthy growth. Coming from habitats with unrestricted access to sunlight, it does not tolerate shaded or low-light conditions well. Too much or too little sunlight can adversely affect its vitality.
What are the sunlight requirements for Santa Cruz Waterlily?
The Santa Cruz Waterlily thrives in full sun, requiring more than 6 hours of direct sunlight daily to maintain its health and vitality. Originating from environments with abundant sunlight, it does not fare well in shaded or low light conditions. Ensuring the right balance of light and shade is crucial for the plant's development, as both excessive and insufficient sunlight can affect its growth adversely. When natural light is not sufficient, especially for indoor cultivation, artificial lighting can be a vital complement to promote healthier growth. It's important to choose the right type of artificial light, such as LED lights, which can mimic natural sunlight conditions necessary for the plant's optimal growth. Different plants require varying intensities of artificial light, with full sun plants needing 30-50W/sq ft, partial sun plants 20-30W/sq ft, and full shade plants 10-20W/sq ft. Adjusting the distance and duration of artificial lighting can further simulate natural sunlight exposure for the Santa Cruz Waterlily.
What are the symptoms of inadequate lighting for Santa Cruz Waterlily?
When the Santa Cruz Waterlily experiences inadequate lighting, several symptoms can manifest, signaling the need for a better lighting environment. These symptoms include the development of smaller leaves than previously produced, leggy or sparse growth giving the plant a stretched-out appearance, early leaf drop to conserve resources, delayed or halted growth, lighter colored new leaves indicating chlorophyll deficiency, and symptoms related to excessive sunlight such as chlorosis, sunscald, leaf curling, wilting, and leaf scorching. Recognizing these symptoms early allows for corrective measures to be taken, ensuring the plant's health and growth are not permanently impacted.
How can you address lighting issues for Santa Cruz Waterlily?
Addressing lighting issues for the Santa Cruz Waterlily involves several strategies, depending on whether the plant is grown indoors or outdoors. For indoor plants, gradually moving them to locations with at least 6 hours of direct sunlight daily, utilizing a south-facing window, and employing artificial lights such as desk or ceiling lamps for at least 8 hours daily can significantly improve light exposure. Outdoor plants benefit from a gradual relocation to sunnier spots, avoiding sudden changes that can cause sunburn. Minimizing obstructions to sunlight, such as pruning tree branches, and transplantation during the plant's dormant period can help in maximizing sunlight absorption. It's important to note that while parts of the plant affected by insufficient sunlight may not recover, new growth following improved lighting conditions will be healthy.
