Helvola Hardy Waterlily – The Miniature Yellow Gem

The Helvola Hardy Waterlily is one of the smallest and most charming waterlilies available, making it a favorite for small ponds, tubs, or container gardens. With tiny 2–3 inch, star-shaped yellow blooms and heavily mottled pads just 1–2 inches across, Helvola packs incredible beauty into a petite package.

Despite its size, Helvola is a vigorous bloomer, producing flowers all summer long. It has a compact 1–2 foot spread, making it ideal for water features where space is limited. While its bloom window each day is shorter (typically from 11 am to 3 pm), the bright blossoms more than make up for it with their sunny cheer and abundance.

This miniature hardy waterlily is an excellent choice for those wanting to enjoy the magic of waterlilies in smaller spaces.
