I found two plants of Kerria japonica 'Pleniflora' by luck the other day, in a plant nursery, after several others had told me they couldn't get it this year...I only saw the single flower version and didn't care for that so much. I really like this shrub, I like its graceful flopping-over shape combined with the small yellow pompom flowers, especially attractive where I saw it along a street, up above the sidewalk in a shrubbery garden atop a stone wall, and the long floppy branches were spraying over the edge of the wall towards the sidewalk. I also saw the shrub this spring planted in a tall narrow pot, with the stems rising up tall and very green, in the protected tropical garden in Butchart Gardens near Victoria... it didn't look so "floppy" for some reason in that style and the green stems looked stiffer, possibly because it wasn't laden with bloom. I am waiting for my two plants, purchased while in bloom, fairly reasonable size, about 2 feet tall, I'd guess maybe a couple of years old, to harden up in their planted location, presently staked to prevent stems breaking. I have planted the original two in a semi-sunny spot, although I see that the plant is recommended for part shade. Since almost everything grows better in sun, I tried this location for a change -- it gets sun after 1 pm facing northwest, and is shaded a bit by a couple of small trees/larger shrubs in the same garden. A couple of the newer stems broke off the root very easily as I was taking the plants out of their nursery pots, and I have dipped them in a rooting hormone and planted them near each other in the garden soil, in a protected semi-shaded spot, trying to keep them moist. One looks a bit wilted, with the top curving over, the other is standing straighter and looks fine. I would like to propagate several new plants, and don't have a track record for doing this. I would like to plant one in a pot in the style I saw in Butchart, possibly growing it indoors in winter... The style of the shrub suits my garden in a couple of spots and the bloom colour is a nice true yellow. Can anyone enlighten me on how easy it is to propagate Kerria from cuttings or from stems from the root?
