Whither the Dahlia?
Perhaps the finest thing about the dahlia is its internationalism, for the varieties grown in this country originated all over the world. This is probably equally true of nearly every other dahlia growing country. This means of course that there are an enormous number of varieties available, but has also meant that the standards of quality have risen greatly over the years.
In addition the committee is responsible both for the selection of dahlias for trial at the Royal Horticultural Societies Gardens at Wisley and for the judging of such varieties. It advises both societies on matters of mutual interest, and is concerned with maintaining good relationship between the two societies and other kindred bodies.
Australia and America in particular have produced some really wonderful varieties which are to be seen in every keen grower’s garden. The medium and small varieties, up to a few years ago, were, in the main, of native origin, but of late years we have seen a gradual influx of varieties from other countries. Holland, in particular, is responsible for a really wonderful range of medium cactus which have literally revolutionised this very attractive section. But France, Germany, South Africa, Australia and the Iron Curtain countries, plus a whole host of other nations, have all sent varieties which are grown enthusiastically, so that it is perhaps invidious to even imply that any country excels in this particular phase.
Mention was made of the Wisley Trial Gardens. In a way these are unique, for no other country works to a better system. The varieties grown at the trials are selected by the Joint Committee from amongst blooms placed before them from time to time during the growing season, attention being paid to formation and colour and to a number of other points. When a variety selected has been for trial, the raiser or introducer of the variety must supply three plants in the following season for growing at Wisley. Here they are grown under good, but not perfect conditions, to assess their value as a garden variety.
It is perhaps a pity that the National List does not include all of these Scottish varieties, but it is not possible for the N.D.S. Committee to classify varieties which they have not seen, so it is only these Scottish varieties which are distributed outside Scotland- and the majority of the worthwhile ones to become so distributed – which can he classified by the Classification Committee. It has been suggested there should be a scheme whereby Scottish blooms could be seen at a Scottish show for classification and perhaps selection for trial at Wisley.
The National Dahlia Society presents a Gold Medal to the outstanding seedling of the year: this, however, is not awarded if, in the opinion of the committee, no dahlia is worthy. These honours are much sought after, as they are the hall-mark of a great dahlia, one which can be bought and sold with confidence.
