I have several lotus tubers for sale. One is N. 'Momo Botan' and the other is an un-named pink. I only have the two varieties but I may have mixed up the two labels. I will send you one tuber of each for $10 plus $6 shipping.
Would also be interested in trading for:
Pygmy rubra hardy waterlily
'Laura Frase' tropical waterlily
‘Red spider’ hardy waterlily
marsh marigold (Caltha palustris not Lesser celandine)
maybe other interesting bog plants
