As a benefit to our members, the IWGS offers two special annual events. We hope you’ll join us for our annual Symposiums. And of course, stay tuned for each year’s announcement of our New Waterlily Competition winners.

Annual Symposium

The IWGS Annual Symposium is filled with educational seminars, networking opportunities, great food, and plenty of fun. Speakers from all over the world provide the latest information on waterlilies and all things water gardening. Past Symposia have been held in Canada, China, France, Germany, Thailand, the UK, and the US. View photos from past Symposia.

The 2015 IWGS Symposium will be held in Lawrence, Kansas from August 12th – 15th. Symposium attendees will have the opportunity to visit beautiful gardens, related businesses, learn from experts and novices alike, and – of course – spend time with other water garden enthusiasts from all over the world!  Via short bus trips, we will be visiting several Kansas City sites.  KC – "The City of Fountains" is also known for its BB-Q and Jazz and we will be enjoying some of that too.

New Waterlily Competition

In order to promote interest in hybridizing new colors, forms, and increased frequency of blooms of various sizes of both tropical and hardy waterlilies, the IWGS conducts an annual competition where hybridizers display their new creations. This exciting competition has resulted in the introduction of noteworthy new hybrids: plants with unusual flower shapes and colors; new leaf patterns and colors; and new viviparous lilies.

The IWGS has held the New Waterlily Competition for 13 of the last 15 years. Approximately 40 hybridizers from 9 countries have submitted over 200 entries. Many of these new waterlilies are available for purchase, so be sure to keep your eye on these beauties as you will want to add these to your water garden.
