Herbs (Lemon Grass)

I bought some Lemon Grass that still had the bulbs from a local store and planted them. This verity is intended for cooking, so not sure what the difference is between the verity I am currently growing.

My wife planted these Lemon Grass bulbs about two weeks ago and there are now a few blades of grass growing. I hope I am successful, because this is a much less expensive option to buying plants from a nursery. I paid 150 Yen ($1.40) for the above nine Lemon Grass bulbs verses 398 Yen ($3.80) for a plant that had three bulbs.
