Looking for 'mailbox' plants
We inherited a very tiny bed around the mailbox with the house. It included 2 Hostas and the Clematis Niobe. Niobe is the only clematis I have not taken a liking to, not that the flowers are not lovely but it just did not grow well in that spot. It tended to mildew badly. The Hostas....well, the mailbox is in full sun.
We replaced Niobe with Clematis Proteus and will see how it does. We also enlarged the bed slightly. I am looking for plants that will tolerate alkaline clay and not grow out of the bed in one or two years. So, for example, I considered Rudbekia but they spread too fast. Salvia spreads too quickly. I don't want a daylily that only blooms for a couple of weeks.
