Gardeners' Notes:


On Sep 19, 2012, Dave_Evans from Kenilworth, NJ wrote:

I don't grow either but, Robert, these are two different plants. There is this 'Starstruck' and then there is the one from Oakes which is similar but called 'Star Struck'.

The one listed here, from Yanski ('90), is greener in color while the Oakes ('87) plants has golden colored flowers with a greener throat. How do we get this page to list both cultivars when the names are so similar?

There seems to be some disagreement about what color "Starstruck" really is. I got mine from the hybridizer, Oakes, so I believe I have the correct plant. It is NOT chartreuse like the description here states, and some of the pictures here show. It IS a very attractive yellow/gold with very large showy ruffled blossoms, like other of the pictures show, and as Oakes describes it, that begins mid-season and blooms into late. Mine was a little slow to establish itself but now that it's adapted to its spot, it puts on a great show every year. My only complaint is that it seems to be sterile. I've tried to use its pollen on other daylilies or to set pods on it and nothing. But as a garden plant, it's tops.

I've done further work with 'Starstruck' and it turns out it's not sterile... read more
