Plant Heritage, the charity working to conserve garden plants, has highlighted 10 plant groups which are not represented within the National Plant Collections.
The organisation says the following plants should be included in plant collections:
Examples of the missing plant groups are featured at the charities exhibit at the RHS Hampton Court Palace Garden Festival in the Plant Heritage zone.
Four new pests have been added to the Government's risk register, which lists more than 1,000 pests and diseases.
The following pests have been added:
- Dendroctonus jeffreyi - a non-European scolytine beetle which only appears to attack Pinus jeffreyi, a species of pine tree very rarely grown in the UK.
- Stereonychus fraxini – a beetle which damages ash in southern Europe.
- Phellinus spiculosus – a fungal pest of oak species in North America.
- Phyllachora maydis with Microdochium maydis – two fungi found in North America that can cause damage to sweetcorn, particularly if found in combination.
Meanwhile, the fall army worm, Spodoptera frugiperda has been reported from new countries in South-East Asia, and, more significantly for Europe, from Egypt. The Risk Register distribution has been updated to reflect these new findings.
