The 3 cultivars you mention are all Early Large Flowered Group, they should flower on old wood in May/June then possibly again later in the season.
They are some of the most difficult to grow ( apart from some of the so-called evergreens ), but now that you have bought them, here goes.
Were they all in large 2 litre deep pots or in small 7-8 cm pots when you bought them ?
If the latter then they should be potted on into 2 litre deep pots for another season, before planting out,at the same time regularly cutting off the top growth to develop a large root system.
The Pruning Group is Group 2 for all the 3 cultivars you mention.
