Growing Lotus from Seed

The iris family have some of the most beautiful flowers in the Kingdom Plantae. Unlike the water lily and water lotus, there is a diverse variety of non-deciduous, meaning water plants that stay leafy and green even during autumn and winter. There are deciduous varieties that exist, but they all bloom quickly and produce magnificent flower displays from spring to summer.


A non-deciduous breed, the Louisiana iris will bud and bloom over with a wide array of climates, making it suitable for Australian ponds, gardens, etc. They are, at least, moderately cold-resistant for a plant and come in the usual spectrum of many whites, pinks, reds, blues, yellows, and purples. They grow in either unobstructed or partial sunlight and vary starkly in their height: from 30cm to even one metre tall.

Planting The Iris

To make things a good bit easier on yourself, we recommend potting the plants even if they are in a pond for ease of feeding, caring, and dividing.

To prepare for the plant, line a container with some newspapers or an equivalent to protect against leakage. Then stuff about 2/3s of it with fed soil. Each iris rhizome (rootstock) should ideally have healthy roots and an already growing tip.

Lotus seeds

Plant the rhizome so that it is near, but not at, the top. Point the growing tip to the middle of the container. Then top up the pot with unfed soil to provide anchorage.

Keep the pot out of the pond for a week or so, routinely watering it till you spot a growth. At this point, you can place the vessel into the pond. The depth can be up to 10cm above the rim of the pot.

If the growing iris is in a wet garden bed or a bog or other, feed liberally with fertiliser or shower it around the plant roots after blooming to build up strength for the following year.

We recommend repotting it on a cycle of one or two years for the most excellent and reliable results for the mighty water iris. All breeds, deciduous or otherwise, are best planted in autumn and are ideal for dividing and potting iris or dividing and feed them in wet garden beds or bogs.
