Gardeners' Notes:

Neutral Clary On Apr 21, 2013, Clary from Lewisburg, PA (Zone 6b) wrote:

Weak and underdeveloped in my garden. I expect them to die out in the coming years. My other ipheion do extremely well.

Negative vossner On Mar 17, 2013, vossner from Richmond, TX (Zone 9a) wrote:

Rating negative as they only bloomed in Spring 2012 and did not return in 2013. Being that all my other ipheions do well, even those planted in less than ideal locations, I conclude this is a weak cultivar.

All the Ipheions and their related subspecies are native to South America (southern Brazil, Chili, and Uruguay) and are called Spring Starflowers. They are great naturalizing bulbs for Texas and the southern United States.

All Ipheon species and varieties bloom earlier in the season in my garden and have happily naturalized in areas with good drainage for 20 years. I love the Ipheions for their very early spring blooms!

All the Ipeion species are hardy, most are inexpensive, permanently naturalizing harmonious bulb species in the southern United States and if allowed reseed themselves will hybridize yielding very interesting color combinations.

This particular Ipheion is a clone, and you must remove spent blooms to avoid seeds emerging not looking pink. Ipheions do reseed, in some areas better than others.
