First Lady Melania Trump Unveils the Restoration of the White House Rose Garden: See the Entire Photo Set, via https://instagram.com/georgedotnews 

Most notable is the absence of the 10 crabapple trees which were part of the original design. However, per a White House official, the shade they were casting over the flowers, as well as root growth, compromised the efficacy of keeping the other plantings alive and healthy.

The official adds the trees were taken to the offsite White House greenhouse to be cared for and then at some point they will be replanted around the WH grounds.
The new flowers are not huge.

The colors are mostly whites and pastels, with some small hot pink roses and a few lavender colored flowers. Also notable, there is no longer the area that most of us note as the location of the “Obama beer summit” at the east side of the garden.

That area has been replaced by new limestone pavers and steps - the release given to press at this event says it will be “the new site for an unannounced art installation.”

This is a new garden, and it is expected to grow in concert across all of the flowers and boxwoods, rather than random replacement of sections or seasonal substitutions.

The predominant ROSE veritable used in the new design is the “JFK ROSE,” a white flower. These are along the length of the garden, closest to the colonnade on one side, and the slope down to the South Lawn on the other.

There is a place at the front of the beds for seasonal displays, but the actual garden itself is designed to remain as is and grow on its own. A diamond-like pattern of boxwoods has also been reissued, part of the homage to the original #1962 design.
