Ask the Expert: Please help me identify this flower/shrub
I would really love to know what sort of bush this is… if you could, I would be very grateful. Brooke

What you have is a vining shrub called mandevilla. It once went by the name Dipladenia splendens but the correct name is Mandevilla x amoena. At my husband’s garden center, we sell a cultivar called Alice du Pont. The plants are hardy in zones 9-11 and live year round. In zone 8 they die back in the winter and came back from the roots in the spring. In all other zones it is treated as an annual.
It loves full sun. Although a little mid-day shade is appreciated. They like plenty of moisture but it must have well-drained soil.
