Hi, I bought a hydrangrea, from a nursery about 3-4 years ago and planted it in front of my house where there is full sun all day till late afternoon. Its blossoms are supposed to be white but i don't know what type now (never seen much leaves .. let alone blossoms). It seems it only tends to sprout several leaves every year ... but thats it. Its the same size it was at the beginning (about 3/4 of a foot) .. and it looks like dry dead sticks until a few leaves sprout in the spring the next year.. and die off in the winter. Whats wrongs with this plant? Or what am I doing wrong? I just water it.. but never done anything else to it.
