Sasanqua season 2018 – 3

In my last post I waxed lyrical about how well two of the five bushes of Camellia sasanqua ‘Hugh Evans’ had performed this year, with larger and fuller blooms than usual. What I failed to mention was that the other three had produced entirely average displays, with normal numbers of normal sized blooms.

Some plants had benefitted from the unusually hot summer but others hadn’t. Looking at the plants I would say that the two that had done unusually well were in more open locations, meaning that they received more light, including direct sunlight and were probably less in competition with nearby trees for water.

I have seen unusually big flowers on C. sasanqua ‘Narumigata’ at Moyclare in Liskeard but the Mount Edgcumbe plants have normal sized blooms. In general I would say that there have been more flowers than normal and in a minority of cases the blooms are bigger than usual. Some plants have fewer buds than normal.

Tentative conclusion: Higher temperatures meant lots of buds produced but also increased risk of drought. Where moisture was available plants produced larger than normal blooms but in most cases dryness offset the beneficial effect of temperature as far as bloom size was concerned. Where dryness became an issue early there was a negative impact on bud production, or perhaps some varieties are more sensitive than others.

I have often taken photos of flowers with a tape measure in front but you would need to do this over a period of years as well as keeping accurate weather records to reach solid conclusions. I don’t trust my recollections from a year ago and with good reason. I was convinced that the blooms on ‘Show Girl’ this year were comfortably the biggest ever but in fact they are the same as last year. About 14cm diameter. I have pictures.


Which makes me uncertain about the comments on ‘Hugh Evans’. Perhaps the two good plants have always been significantly better and I’ve just not noticed. If that were the case then some factor(s) other than weather would be indicated, perhaps some have a virus, or are in poorer soil. With plants, there are always so many factors in play that firm conclusions are almost impossible to make and the people who pretend otherwise may not be the experts they would have you believe they are.

Winters-Rose-3

Camellia ‘Winter’s Rose’

A couple of plants in Section 1L have been outstanding this year too, ‘Snow Flurry’ and ‘Winter’s Rose’. Both are from Dr William Ackerman’s program of breeding cold hardy varieties aimed at extending the area where Camellias could be successfully grown in the USA. Both were planted in 2000 and this is the first year they have performed at all well. By far the biggest change in their fortunes was the loss of the mature beech tree under whose dense shade they were languishing. Add one hot summer and a level of maturity and you have two plants you’d recommend to anyone.

It goes to show how easy it can be to write something off as poor when all it needs is the right combination of location and time to prove itself very good indeed.

Snow-Flurry-7

Camellia ‘Snow Flurry’

Lastly, I took these pictures a couple of weeks ago of a sport on Camellia ‘Hugh Evans’ at Mount Edgcumbe. Sports on Camellia sasanqua are comparatively rare and I took a couple of cuttings from this shoot earlier in the summer but left a section of the mutated bit on the bush in case they failed. I was pleased to see the flower as it confirms there is still some on the parent bush. It’s most likely chimaeral so I’d like to grow it for a few years to be sure it’s stable before I launch it onto the world and make my fortune.
