Does anyone know where I can buy one of these plants?
Also, I have read that they don't have seed. Is that a fact? If not, where could I buy seed, please?
Wow that takes me back some years.
They were very popular a few decades ago and the flowers looked just like prawns (or shrimps depending on your location).
I bought one and the cat ate all the flowers
Odd that. The cat was never a nusiance when we ate but on the rare occasion we could afford prawns (they used to be a luxury) she always cried for a share.
