Paperwhites or narcissus are named after the mythological character Narcissus. There a few different versions of the myth of Narcissus (some including the nymph Echo & a curse) but most end with the haughty handsome boy falling in love with his own reflection in a pond and staying there loving himself until the day he dies. (hence the term "narcissist.")
A narcissus flower is said to have bloomed in the spot after his death.
2. Add 2-4 inches of stones, pebbles, gravel, anything non-porous to your container. (This keeps the bulbs in place & out of the water.. you just want the roots in the water.)
3. Add the bulbs. If you're doing multiple bulbs , make sure they're all at the same level & nestled into place so you can keep the roots (not bulbs under water- bulbs will rot)
Buy (already started/ forced?- It was hard to tell) bulbs here: $16.95 for $25
And here there's a deal with 30 for $19.95 and 15 for $10.95
I'd also heard that Walmart has them but don't have one near me...
