The more sun exposure you give to immature blooms, the faster they will turn white. If you want to extend the life of the greens, provide more shade. My LL blooms are still greens in bright shade; they first opened in mid June. LL originated from Limelight so you would expect the bloom colors to be, eh, about the same, adjusted if one bloomed earlier than the other.

It's true that sun will cause the green to fade sooner but Little Lime IS greener than limelight. I have them side by side, both in shade and sun and the little lime start out much greener. Much. I love the green.

What size are your Little Limes? I have a very young one and not sure where to put it...

Mine is about 2' tall. It still has green blooms. I placed it on the north side of the house and gets bright shade all day in the summer.

Little Lime is supposed to get up to 5' tall.

Thanks for the help on the color of Little Lime and Lime Light.

I think I might get another Lime Light and try to dry some blooms and then maybe dye them. I have read where you can do that but I have never tried.
Best to all my gardening friends.
