Earlier, Buckingham Palace had explained the significance of the card and floral arrangement atop the Queen’s casket. The Palace said in a statement to E! News, "At His Majesty The King's request, the wreath contains flowers and foliage cut from the gardens of Buckingham Palace, Clarence House and Highgrove House. This includes foliage chosen for its symbolism."
The Royal family also tweeted that “the wreath contains foliage of Rosemary, English Oak and Myrtle (cut from a plant grown from Myrtle in The Queen's wedding bouquet) and flowers, in shades of gold, pink and deep burgundy, with touches of white, cut from the gardens of Royal Residences.”
