“One has a lot, an endless lot, to learn when one sets out to be a gardener.”
Vita Sackville-West, A Joy of Gardening (1958)
After writing about Winter Whites last week, referencing the ubiquitous white camellia hedges, of course I noticed this hedge on my way to town. My eye was drawn to the composition of brown and white flowers. It is a japonica camellia, though which one I am not sure. Closer examination revealed a bad case of petal blight, even this early in the season. There are two main giveaway signs. The first is the brown flowers hanging on to the bush. Most modern camellias are what is called self-grooming. They are bred to drop their spent blooms but those affected by petal blight hang on. The blighters. The second sign is shown by turning over a brown bloom and removing the calyx that holds the petals together. There is the tell-tale white ring of death – fungal spores. There is no remedy. You either live with it or you remove the plants.
I have never been a fan of japonica camellias for hedging. The foliage can go a bit yellow in full sun and both leaves and blooms are too big. Smaller leafed camellias, seen in the sasanquas, some of the species and the hybrids look much better. Miniature single flowers usually fall cleanly and disintegrate quickly, avoiding the sludgy brown effect below.
While some claim that sasanquas can get petal blight, we haven’t seen it on our plants. And although the single flowered species and hybrids are not necessarily resistant, most set large numbers of flowers but each bloom only lasts a few days so they fall before blight takes hold.
On another topic, winter is pruning time. I did the wisterias on Friday. This is one plant family I recommend removing totally if you are not willing to prune them. They have dangerous proclivities. Most of the roses are done and I have started on the hydrangeas. Those in colder climates may be better to wait another month before tackling the last two because pruning encourages new growth which is vulnerable to frosts. The pruning guides I did several years ago as part of my Outdoor Classroom series give step by step instructions if you are not sure where to start – wisteria, hydrangeas, roses.
