Jersey Snowflake/Jersey Snow Drops ...

As you can see, though the plants are similar in appearance, there are noticeable differences ...

Jersey Snowflake has flatter, somewhat darker, shinier foliage with a more prominent white trim.

Jersey Snow Drops foliage is more up-swept, and there is not as much variegation.

Also, Jersey Snow Drops flowers have a center petal or two ... which tends to obscure the central (yellow) stamen.

They are both nice nice plants, especially for whites. The blooms of both plants are long-lasting and don't fade/brown until they begin to droop ...
