hi all,
i am a newbie on lilies so please bear with me.
a friend works in a florist shop and last year after easter, she gave me a leftover "easter lily". i read up on them and planted it with the roots shaded and the top to eventually be in full sun. it stayed green a good long time and then slowly died down to nothing. early this spring (february) i clipped the dead stalks off and a few weeks later green started sprouting up. the way i understood it, this particular lily doesn't get very tall. the two stalks just started opening up this week and one stalk is about 3.5' tall and the other is a good 5'. is this normal?
i've attached some pictures to get a hopefully positive id.
thanks so much.

the third image is supposed to show a yellowish/gold line running along the outside of the petal.
