I would be patient till at least mid June and then, if there's no growth, dig it out.
I have a black lace that I've allowed to grow tall but I've removed the lower branches to create a shady canopy for woodland plants. Since I did that 18 months ago, the stems are thick with new buds of purple foliage.
The golden form is much less hardy though I have one in a sheltered spot that is doing well. It's parent, further along the boundary and more exposed has been frozen back to a shadow of its former self as a result of the last 4 hard winters here but both have lovely fresh golden foliage with bronze tints in spring so it's worth finding a spot for one.
