Wai Kru Day: The Flowers Thai Students Give Their Teachers
The flowers and plants associated with Wai Kru, and how families can follow their school’s own ceremony instructions.

Wai Kru is a ceremony of respect and gratitude towards teachers. Thailand Foundation describes school ceremonies commonly taking place on a Thursday in June, while practices extend beyond schools. The date and requirements should come from the institution holding the ceremony. Thailand Foundation's Wai Kru guide.
The plants and their associations
The Foundation discusses Bermuda grass and eggplant flowers, with ixora and popped rice also commonly used. Its account connects grass with resilience, the bowed eggplant flower with respect, ixora with sharp intelligence and popped rice with growth. Popped rice is not a “popcorn flower”. These are cultural associations, not a requirement that every ceremony use an identical tray.
If your school asks for a phan, a pedestalled presentation tray, get its specification rather than choosing a decorative bouquet and assuming it serves the same purpose.
Ask the school first
Find out whether students make the arrangement in class, families provide materials, or a completed tray should be brought in. Ask about dimensions, permitted materials, the receiving time and whether a child must carry it unaided.
Do not assume every family is expected to purchase an elaborate arrangement. If the school has a simple materials list or a shared class activity, follow that plan. A clear question to the teacher is more useful than a generic price guide.
If you are ordering an arrangement
Send the school's instructions to the florist. Confirm the components, tray or vessel, size and collection time. If a required material is unavailable, ask the school whether an alternative is acceptable before approving it.
Explain whether the tray is carried by one child or presented by a group. Keep the construction manageable and confirm how it should be transported. If candles or incense are part of the request, follow the school's directions for handling and use.
Preparing for the morning
Arrange a handover that leaves time to reach the school. Check whether a courier can enter the grounds or whether an adult should collect at an agreed point. Keep the school's receiving contact and the florist's order reference together in case the schedule changes.
For a group order, nominate one person to approve the final specification so several families do not give conflicting instructions. Confirm the quantity and any names to be attached before the florist starts.
FlowerRova enquiries
This guide does not promise a standing Wai Kru tray service, fixed price or a universal one-week cutoff. Contact FlowerRova with the institution's requirements to check whether the request can be accommodated. If a specialist ceremonial maker is needed, choose one who can fulfil the actual specification rather than substituting a catalogue rose bouquet.
