Thanks for the great info Tamara. Wondered if you could help with my question about a 6 month old lemon grass plant that is growing seeds. I've never had that happen before & don't know whether to be worried or pleased. The photo shows the lemon grass in front of my asparagus - cut back for winter here in oz & being closely cuddled by a sweet potato vine.
It depends on the strain you are growing, I have been growing lemongrass here on Reunion island for twenty years and never had a single seed, then a friend gave me a small plant he ha obtained from seeds he purchased and this one does set seeds, it can even become invasive. I would say that the seeded one is somewhat larger and with tougher seeds than the non seeded one.
Hmm, not sure at all how to answer this one - a true sign of a great question! For many plant species, going to seed means that it's reaching the end of its life. I can't say if this is true for lemongrass. If it were me, I would cut off the flowering stalks in hopes that it would extend it.
I can't answer your original question about the seeds, Pottager, but the question about different strains caught my curiousity.
According to The Illustrated Encyclopedia of Essential Oils by Julia Lawless, there are several varieties of lemongrass. The two main ones are West Indian Lemongrass (Andropogon Citratus) and East Indian Lemongrass (A. Flexuosus). They are cultivated for fragrance and food uses, and to dilute more expensive essential oils such as lemon verbena and melissa (lemon balm).
West Indian lemongrass sounds like it is more common, being grown in India, Guatemala, the West Indies, Africa, and tropical Asia.
Lemongrass is delicious in Thai food and is often combined with ginger and lime in curries. Very light, bright flavor!
I have sent for lemon grass seed. The variety is Cynboogan citratus. Living in the North West I plan on potting it and leaving it outside in summer and bringing it in when the weather cools.
I've never done lemon grass. Any suggestions would be appreciated.
