If you want to continue to be helpful, let's play Name That Plant. What is this, which hath sprouted in my garden?
Keep in mind I'm in Seattle, therefore it's probably not tropical. For ID help: the flower has no scent that I can detect, nor do the leaves. I wish it weren't pink, but since it's so low-maintenance, it's welcome to stay. Why are so many flowers pink? Oh well.
Want your kitchen to smell good? Buy a small amount of garam masala spice mix from the bulk spice bins at your grocery store. Leave it in a plastic bag on your counter. Voila--whole kitchen permeated with aroma of coriander, cumin, cinnamon, clove, pepper, and whatever else goes into garam masala. At least, that's how it has happened for me.
P.S. I had to delete a Shakespearean greeting using the name "Coriander" just now.
