I forgot to cover it one night in February and the frost hit it, all the leaves were brown and eventually all fell off. I started to dig up the bulb and throw it away, but something told me to wait, and IÂm Sooo glad I didnÂt trash it because the new limbs are shooting out from underneath the mulch with new soon to be green leaves and it looks as though it will be taller than it was when I purchased it last year. I am sooo HAPPY!!! Next year I will be sure to Mulch, Mulch and more Mulch. Gina
