Daffodils at their peak

So visitors not only get to see all the newcomers but also those whose standard they have to reach. And the result is a colourful collection of intriguing varieties - and now's the time to see them. Take note of those you like ready to order for planting in the autumn.

The assessment panel has been looking over the plants since long before they started flowering, keeping their eyes open for disease problems, but now that flowering is well under way a number of the new entries have proved especially impressive.

And unlike some varieties of the hoop petticoat (bulbocodium) type ‘Classic Gold' is proving a robust garden plant.

Another of the stars ‘Patrick Hacket' (first picture, click to enlarge), they described as "outstanding, a very impressive entry with a good flower count with the flowers held well above the foliage."

This last feature, how the flowers are held in relation to the foliage, let down some of the entries. ‘Akita', ‘Andrew's Choice' ‘Blues' proved especially disappointing in this respect.Narcissus 'Sabrosa'. Image: ©Sue Drew/RHS Trials Office

Those early visits, on the watch for diseases and other problems, produced plenty of work for the Wisley pathologists but it was mainly individual bulbs rather than whole entries which were affected. Some were damaged by this last winter's severe frosts, but basal rot, neck rot and virus were also in evidence along with eelworm. Interestingly, a few bulbs had been damaged by the hot water treatments used by bulb producers to kill eelworm. The vigilance of the assessors before the plants even bloom ensures that problems do not spread to the rest of the trial.

If you're worried about problems with your own daffodils, the RHS has some useful advice:
Basal rot,    Virus,    Blindness and poor flowering

And don't forget to take a look at the daffodil trial while it's at its peak.
