Vanessa: I agree with Chelle, as your
Sweet Viburnum (Viburnum odoratissimum) matures it will have many more spikes of flowers. Is your plant container grown, or is it in the ground? I don't have much insight as to the culture of this plant grown in containers, ours were planted in the ground many years ago and stand @ 15' tall. They've never been fertilized and get watered twice weekly when the irrigation system is on and have done very well over the years so they must have been happy with the location where we planted them. Sweet Viburnum is really beautiful in spring when it bursts into bloom and I agree, the fragrance is really nice!
