The body has said that gardens are less likely to be blighted by roe, muntjac or fallow deer if they opt for the yellow flower, as well as red hot pokers and butterfly bushes, because the animals are put off by the taste.
The RHS surveyed members to see which of the mammals they saw in their gardens and what damage was caused.
Nearly 800 gardeners completed the survey from across the country, with 2,000 records of the effects of hungry deer on 185 popular garden plants.
The survey found roe deer were the most commonly sighted, in 65 per cent of gardens, followed by Reeves' muntjac which were seen in 41 per cent of gardens, while fallow deer were spotted in 9 per cent of the gardens of people responding.
If they could see deer had tucked into a plant, people were asked to record the amount of damage on a sliding scale from untouched to impossible to grow.
Where there were more than 65 entries for a plant, the researchers used the scores submitted to work out a percentage likelihood of it being eaten.
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."
