Hello joelizzie, is Choisya ternata sundace? i think you may be ok, but would leave a while longer before trimming back just in case we get another cold snap, it should put some new growth up soon but be a little patient, i was looking at one today that has been affected by the frost and new growth is starting to break through further down, however there are some that look completely gone that i have seen on my travels, but yours may be ok just wait a little longer.possibly slightly trim early may. julien

I'm not sure which type it is as it was already in the garden when I met my husband, but thanks for the advice, I was thinking that may be the answer. Thanks again.
