The Bedding & Pot Plant Centre, run by ADAS at Baginton Nurseries in Warwickshire, is set to look at verbena, hellebore and spectral filters among other projects in 2016.
ADAS consultant Chloe Whiteside said a spectral filter trial will repeat with autumn varieties, having previously covered spring and summer varieties. A spectral filter trial on glass coatings without plants will also take place to get background data, she added.
Verbena has had problems with nutrition. Whiteside said a trial is being put together on that subject. There will also be a trial on improving cutting materials using different varieties.
A hellebore trial looking at different coloured varieties for sale at Christmas will start in 2016. One or two more trials are to be decided.
WD Smith director Michael Smith, who helped set up the centre, said it has been a "learning curve" but he is "very pleased" about the site and its progress.
He added that having the appropriate site and having the right projects on trial at the right time is the focus. Ideally he wants them to be ready to coincide with the HTA National Plant Show next June.
A recent open evening featured tours led by Jill England (ADAS), Chloe Whiteside (ADAS), Harry Kitchener (independent consultant) and David Talbot (ADAS).
The trials completed or underway in the first year of the project included "Temperature Effect on Days to Flower", "Pre-Christmas Production of Hellebore", "Seed Raised Versus Cutting Raised Calibrachoa & Begonia Boliviensis", "Spectral Filters (Film)" and "Overwintered Perennials". The latter three were available for viewing.
ADAS has called for plants with pansy mottle syndrome to be sent in to consultant Chloe Whiteside or Jill England. There have been reports of the problem in both the north and south of the country.
AHDB Horticulture-funded project PO 016a - "The role of environmental factors in the incidence of pansy mottle syndrome (PaMS)" - is currently being carried out by ADAS.
