While the post said nothing of a tribute to Princess Diana, it did confirm that white garden roses will come into play in the arrangements. There will also be "branches of beech, birch and hornbeam" and "peonies and foxgloves".
The Sun also obtained information about the arrangements. Sources have said that the white garden roses, meant to honor Princess Diana's memory, will be placed next to the peonies, which are Meghan's favorite, and the foxgloves.
.@RoyalParks will supply some pollinator-friendly plants from their wildflower meadows that will be incorporated into the floral designs. These plants provide a great habitat for bees & help to nurture and sustain entire ecosystems by promoting a healthy & biodiverse environment.

A previous report suggested that Meghan may honor the late Princess by wearing a Spencer Tiara on her wedding day. Royal experts have said it's highly likely she'll go this route.
