Linda,

I'm taking a guess, but I have Desire which is an orange with a pinkish tint to the midribs which yours appears to have also. Yours does seem to be a lighter orange than Desire but as yours is growing outside in the ground that might account for the color difference but as I say this is just a guess but, as I look more closely at yours again I'm noticing those two small greenish streaks that my Desire doesn't appear to have so maybe someone else will come up with a better guess.

Here is my Desire:

It looks like some Hippeastrum of the "orange complex" in other words H.petiolatum. This one reminds me of some "Klister" Hippeastrum from the "xxxxxxx Garden" series!
