He he he.... maybe we can meet up in mid Dec. I'll probably have some Red Tiger Lotus and Green tiger lotus (offcuts/young plants). What's the price of a small Tiger Lotus plant in KL at the moment? Nuphar Japonica I haven't seen here in sydney, but there's the Spatterdock which is the American cousin of the Nuphar sp. I believe. Could probably get the rhizome if you want.

Glossotigma is kinda seasonal... haven't seen any around for a while.

Hey, maybe you could try the aquatic plant farm in Seremban? Alternatively, visit Zen WaterGardens in Taman Desa. They design planted tanks as well (other than koi), and they could possibly get your the plants you want too.
