Oh absolutely, Jane! The seeds for these are sold in the UK as tropical climbers. I'm not sure how they'd survive the winter, but they flower in the first year, and set seed very easily, so you'll be able to grow them. The most common ones are white and blue/white, and each of these comes in single or rosette type flowers. I've picked some rosettes now, will tag you in a snap. @pelly
@AnkitaPKarthik the thing is, Trikaya sells herb pots in select Indian cities. These plants include lavender, and I'm absolutely mental about them (I'll tag you in a bit). they don't sell these in Pune, but may do in Delhi.
