With Daylily Society friends

Volunteer mornings on the island are happening again. Every Thursday morning at 9 AM and some Saturdays (TBA). Watch this site, your email, and Facebook. We can use a few hours help. Always free irises for volunteers!




We need help at our iris nursery!

We are asking our members and friends to give us a hand for a few hours on Thursdays between 9:00 - 11:00 AM. The may be some special Saturday volunteer days from time to time.

There will be tasks at various levels and including some in the shade. There is always weeding to do, but we also will be dividing and labeling pots of irises and propagating new plants from old rhizomes.

Everyone who helps will get a free Louisiana iris rhizome!

Please bring gloves.
