A mixture of heirloom paperwhites, including Early Pearl (perhaps the most abundant), Stars (also known as Minor Monarch), and Grand Primo (fewer of these).  There could also be some unidentified varieties which have survived in old gardens.  This mix was originally sourced in North Carolina.

These are Tezetta Narcissus hybrids, so like a standard Paperwhite they force well, unlike them they are great naturalizer's in zones 7-10.  These are a step above your usual Paperwhite's, with great scent and greater ability to thrive outdoors.  I have heard they are more cold hardy but cannot say with confidence what types will survive outside below zone 7.  

When grown outdoors they flower in winter and spring.  

In colder climates these are easily forced inside for winter blooms. Bright light will help prevent legginess and encourages strong stems.

Very nice large Bulbs, grown in the USA!
