Count Tibor Kalnoky, a close friend of his grandfather Prince Charles, made the symbolic present to raise the profile of the region in Romania.
"This gift will protect this area and contribute to raising public awareness, so that rare flowers can be protected," he explained.
"If we sent him flowers, they would wilt, so this is a symbolic gift. Wild flowers are fragile like new-born babies."
According to The Telegraph, the conservationist manages two rural properties that Prince Charles bought in Transylvania, a region the heir to Britain's throne has been attracted to for its sustainable rural life.
Among the gifts received by the future King of England were a hand-crafted pine toy box from Prime Minister David Cameron and his cabinet.
The box is the creation of family-run firm Hibba Toys UK in Leeds, owned by British Asians Waheed Ahmad and wife Lubna. The 325-pound wooden piece features rope handles, a hand carved teddy and soldier.
Hibba Toys has been run by the Ahmad couple for eight years and was named after their 10-year-old daughter Hibba.
His maternal aunt Pippa Middleton's gift of silver casts of his hand and feet made by a bespoke London company and worth around 7,000 pounds were among the more unusual gifts.
