Plant
Begonia tubers in a flat box in a mixture of potting compost and sand. Place the tubers in a 2-3 inch layer and keep them moist and moderate warm (60 -65 degrees), at a sunny location. This will enhance early sprouting and rooting of the tubers, harden the plants off by the end of April - early May and transplant the plants around second week of May into planters or the border. Be careful that a late night frost wont damage the tender plants. If night frost is expected, cover the plants for the night with an old newspaper.
Begonia plants like a lot of water, feed them regularly with a summer plant fertiliser.

Hosta that will provide some shelter against strong winds as it can split the leaves or scorch the edges.
