V. I have just planted 2 Formosa's... Spring Gold and Spring Magic... both in partial shade bed behind a viburnam bush. Have widened the bed this year as the viburnam was encroaching. Nice opportunity to introduce some new varieties. These 2 look great alongside lamium, heucheuras,pulmonaria and a few freebee cowslips, aquilegias etc.
I also grow Alba in my white border and it looks better than ever this year. It will be joined with a few touches of purple this year. All white can look a bit flat and needs a touch of colour... but I think we have discussed this already.
