Full speed ahead for 2015 trials

You might think it's a quiet time of year but the trials team are still very active, both indoors and out

There is some assessments of trials still occurring, such as our Hamamelis trial held at Witch Hazel Nursery in Kent where we are assessing 136 cultivars. The owner, Chris Lane, holds the National Plant Collection of witch hazels and will hold an open day on February 1st 2015 - why not pay a visit and enjoy their colour and fragrance?

The Hippeastrum trial beginning to flower in the glasshouse corridor at RHS Garden WisleyOur Hippeastrum trial is now starting to flower in the glasshouse corridor (see photo, left). Here we have over 70 varieties in the trial, which will be made accessible to the public in due course.

In the back office the Trials Officers are planning the assessment dates for 2015 with the forum members, and planning new trials for 2015 such as the vegetables - which this year include, leeks, Brussels sprouts and borecole/kale.

One very large new trial in 2015 will be a sunflower trial. This trial will be assessed for AGM (RHS Award of Garden Merit) and the RHS People’s Choice Award. We are working with Fleuroselect, the international organisation for the ornamental plant industry.

The trial will be planted in the Hilltop Borders and in containers along the pathway up to the Hillside Events Centre. In this trial we will be having over 100 cultivars of tall and dwarf types, so be sure to come and see us over the summer.
