Don't know it but wouldn't bother with a C. florida in a humid cold zone 5

There are a number of variegated forms of C. florida - 'Firebird', 'Cherokee Daybreak' and 'Cherokee Sunset' are common to the trade. Have not seen 'Rainbow' sold in this area but then C. florida is less favored here (compared to C. kousa or the hybrids) due to a high propensity for anthracnose. All will get pretty amazing fall color. 'Welchii' is another, less common variegated form. All variegated dogwoods benefit from some protection from hot afternoon sun.
