What a beautiful garden, Jack

I am particularly taken with the lovely big slabs of rock and the water feature.

I see plenty of ornamental grasses which are also a big win for me.

It is really nice that you planted those Redbud. In our zone they sometimes do not make it, and they are such beautiful trees.

Violas are considered half hardy annuals and they tend to self seed, so you may never run out of them,
