The results are in from my 2001 trial of various miniature daffodils (narcissus, if you insist). For sheer staying power, 'Jetfire' is the winner by a mile. It's even spreading, so it qualifies as a naturalizing bulb (as opposed to perennializing, meaning returning for several years). 'Thalia' and 'Tete-a-Tete' tie for second place, still popping up after five years but in diminishing numbers. And the varieties that have proven to be short-lived are: 'Pipit,' 'Bell Song,' 'Jack Snipe,' and 'Hawera,' and all of the doubles. None of the contestants received any attention on my part - surely we all have better things to do than pamper our daffodils.
