Summer Skys flowers open cream and mature after a few days to pure white, it is very similar in habit Summer Break, same strong stems and big flowers. In the greenhouse at our nursery, we expect to see the first flowers in early April and they continue until the first hard frost, outside they flower from early June. Unfortunately due to a problem in production, there will be no plugs of Summer Sky this year, but we will have a limited amount of plants available for shipping in mid to late May.
