Q.Growing of spearmint plants
I would Like to grow spearmint plants indoors. I live in India. Are spearmint seeds available in India? If so, can I contact someone for help or information? Please help.

I would do a internet search for herb seeds.
You should have no trouble finding a seed supplier that ships world wide.
There could be issues with shipping seeds though as some countries have restrictions.
You may need to contact Customs to find out if seeds can be shipped to you.
Here is a link about growing Spearmint.
