Gita, the lemon/lime basil seed was an accidental mixture of lemon basil and lime basil (both thai types, I think, with small pointed leaves).
The small bulbs weren't crocus bulbs (didn't bring any), and not muscari (ditto). I think they would have been either Iris reticulata 'Harmony' or blue Scilla siberiaca. In any case, with fall-planted bulbs you want a hole 2-3 times the diameter of the bulb. For a little bulb that's about an inch across, you dig a 2 inch deep hole, put in the bulb, and add an inch of soil on top. Little bulbs are super easy to plant if you are planting perennial or digging in bigger bulbs... just stick them in before you fill in that last bit of soil... dig less, plant more!
