I have tons of Spring Starflower. Can anyone tell me any difference between 'Wisley Blue' and 'Rolf Fiedler'? I can see no difference at all in any images anywhere. If there's any difference, it must be so subtle that it would take a DNA test to point it out. One stand of these flowers can produce subtle shade variations depending on sunlight, moisture etc but that can be said for many other flowers and plants.

At first I was disappointed at how small the plants were. Literature says 3-6" high, in my garden they are 2-3": high.

Mar 2012: I have warmed up to these wonderful little plants because of their beautiful blue color, because they are early harbingers of spring, and because the blooms last a long time. I will grow more of these and add other varieties to my garden.

Mar 2018: slowly expanding.

A great plant suitable for dry to near xeric conditions. Survived the drought of 2005-2006 here without any problems or irrigation. Becomes totally dormant in summer.

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--but in Texas they should not be confused with either the Prairie Celestial Lily (Nemasyylus geminiflora) or the Prairie Nymph (Herbertia lahue). These two species are both native to Texas and quite frankly very different with very obvious flower and bulb morphology differences from the Ipheions.

Ipheion 'Rolf Fiedler' and other related Ipheon species 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!

I don't find the variety ... read more

This cultivar's color far surpasses that of 'Wisley Blue,' being deeper and not faded. Probably the best cultivar of the species, being resistant to winterburn when established.
