The Mexicana Water Lily has small bright yellow blossoms that bloom like tropical water lilies. The lovely flowers are open from midday, to late afternoon. Even though it is not a true "hardy" water lily, Mexicana will over-winter in zones 5 or greater (with care).

First discovered in Mexico, the Mexicana Water Lily is also known as the Yellow Water Lily, Sun-lotus or Banana Water-lily, and easily grows in marshes, readily invading canals and other shallow waterways, often becoming a great nuisance if left unchecked in an open ecosystem, such as a farm pond or lake.

What To Expect With Mail Order

Plants you receive by mail need time to adjust. Your water lily will arrive Bare Root (only root and little to no foliage). Upon arrival, they may not appear lush but given time & proper care, they will flourish!

Planting Instructions

Use Plant Bags or Plant Baskets to plant your water lilies. Plant each tuber with the growing tip facing outward. Fill in around the tuber with aquatic planting media, making sure the roots are spread well and the crown is sitting just below the soil surface. Place in shallow area of pond to encourage faster growth. Once new leaves have reached the surface, water lily can be moved deeper into the pond.


Water lilies should be fertilized throughout the growing season. CrystalClear® Thrive™ Aquatic Plant Fertilizer or TetraPond® LilyGro™ Aquatic Plant Food or Laguna Plant Grow Fertilizer Spikes can be pushed into the soil at planting time and from April through August, following all manufacturers' recommendation for fertilizer application rates.

Plant Maintenance

For best results, trim or prune water lily as leaves and flowers begin to turn yellow or brown, remove them completely, discarding them to keep as much excess organic material out of water-body as possible.

Winter Care

Water lilies on plant-shelves, in planting containers, should be trimmed to 1 to 2" and then gently lowered into deeper water. All plants submerged before winter must be brought back up as soon as the ice has permanently thawed, and before any plant growth occurs. In Zones 6 and warmer, most pond plants can tolerate being left in place without moving them at all.


Due to the quick growth of the Mexicana Water Lily, it is extremely invasive in states where temperatures do not reach freezing. Never release these plants in public lakes or waterways in any state.
