It revealed that some popular plants faced a major risk of damage – with a more than 40 per cent chance of being chomped – including tulips, roses and holly.
But 85 plants were large shunned, with a minimal or less than 20 per cent risk of damage, including daffodils, bay, primula and nerine.
In the case of daffodils, they are known to be mildly toxic, which could account for why they are less appealing to deer.
Deer populations have soared in recent decades and are thought to be more abundant and widespread now than at any time in the past 1,000 years.
They have expanded due to milder winters, changes to farming practices and escape from parks and farms.
Jenny Bowden, horticultural adviser at the RHS, said: “Our findings suggest that deer have a taste for certain plants, although it’s worth remembering that what is a food favourite in one garden might not be in another.
“While a little bit of damage won’t mean you’ll want to give up, if damage is sustained and bothersome, switching to plants shown to be less appealing might do the trick.
“You never know, you might also be inspired to grow something new.”
