Thursday night’s sudden sub-zero temperatures ruined the display of some Magnolia varieties, whilst others remain virtually unscathed. ‘Athene’ (see picture) has suffered severely along with ‘Todd Gresham’ and ‘Milky Way’. ‘Apollo’ has less damage. ‘Raspberry Ice’ and several others seem unaffected. I think it is down to the varieties rather than their position in the garden, as plants adjacent to each other have had greatly differing levels of destruction.
