From what I have read, hellebores are supposed to spread. I have a few I planted four years ago, and they seem to be the same as when I planted them. They are planted in a bed of vinca. Should I remove more vinca that surrounds them? I do fertilize them and protect them with a winter mulch. What else should I be doing to have more plants?
Hellebores increase slowly into clumps so have patience, counsels Chris Darbo, wholesale manager of The Natural Garden, St. Charles, and an enthusiastic hellebore grower. “I have Helleborus foetidus, which has finely cut leaves and blooms in January, and H. orientalis, the Lenten rose. Both have increased in twelve years to four times the size of the original plants, but they haven"t self sown. They are planted in a bed of sweet woodruff in a partly shady location.”
“I also have a clump of H. orientalis that was transplanted into my back yard five years ago, and it seeds all over the place. It is planted in shade with no ground cover. My theory is if the seeds can"t reach the ground, they can"t grow!” It takes three years before seedlings bloom.
According to Darbo, hellebores do not need fertilizer. She never rakes leaves from garden beds but instead lets fallen leaves act as a winter mulch. Leaf decomposition over the years has helped her soil to become more loamy.
H. niger, the Christmas rose, does not self seed as readily as H. orientalis and H. foetidus.
Note: A new strain of H.orientalis has recently reached the market. Known as the Royal Heritage strain, it includes colors and patterns never seen before in the species. Fifteen years in the making, Royal Heritage hellebores were developed by John Elsley, Director of Horticulture at Song Sparrow Farm in Avalon, Wisconsin.
When is the best time to cut back hydrangeas? How far do I cut them back?
Why do I have brown areas near the tips of my dwarf Japanese junipers? This has been occurring the last few years. They are supposed to be drought resistant”
We moved into a house with a lovely azalea that didn’t bloom. We thought it might have been over-pruned. Last fall we did not prune it and now it still hasn’t bloomed. I was hoping to transplant it this year, but it looks rather sickly. Shall we prune it again and give it another year? Can I still transplant it?
