Beautiful in the garden and as cut stems in a vase, delphiniums are loved for their strikingly tall flower spikes and rich array of colors. These hues range from the palest blue through to rich, deep purples, as well as shades of pink, lilac, and white.
If you live in a chilly zone and know how to overwinter a garden, you may well have cut your delphiniums back already. Yet protecting them through the colder months doesn't stop there.
