One of the most unique flower presentations out there.
Volleyball to beach ball sized flower groups of differing lengths composed of star shaped florets. Shorter florets grow out a couple inches - female; longer (outer ring) out to 8"+ - male. 2 tier effect.
One supplier describes it as 'bizarre spaceship with many antennas' (B&B). May be suitable for forcing. Most bulbs imported from Israel (I think). Another description says it presents a fireworks-like appearance (JS).
First time viewers always inquire and are usually utterly amazed.
Circa 1896. Another supplier lists a historical cultural date of 1594.
One's grown in my garden (Z6a/5b) usually last but one season if it's a cold season, warmer winters they survive.
Supposedly forcible over winter; my first attempt didn't.
