Ive gotten really into Gardening the past 2 years an i bought a Butterfly bush Summer of 06 an in the spring i think it was May, June from what i remember it appeared dead, It was all grey no life to it by the way it looked so i decided to cut it down an dig it up, When i cut it down i noticed the inside branch had green in it ive been wondering ever since if it was still alive?, I bought 5 more Bushes last Summer an am hoping they survived over winter, I am wondering if it takes awhile for it to look alive because i dont wanna dig them up if their still alive, So please give me any information on this thank you.
