The Yesterday-Today-and-Tomorrow plant is a shrub grown for its flowers which bloom as purple then change to lavender and fade into white. All three colors can be found all at once when the plant is in full bloom. The variety I have has fragrant flowers.
This plant becomes dramatic when in bloom. Below is a picture of the shrub in our front yard. A few weeks ago we had to uproot it to give way to another plant.
We have another one of this shrub in one corner of our garden anyway. I prune it occasionally to keep it compact and dense. I seldom fertilize it but it looks healthy. I guess it likes the spot where it is planted.
Around its base, underground runners form and can be transplanted as new plants. This is how I propagate our shrub. I have tried it from cuttings but I had no luck. So far I have three seedlings grown from runners.
I will try to use one of them as a bonsai material. Its trunks and branches has a natural movement so I think it will work…
