Maple Tree's Answer · Hi Gabriele-The Rhododendron 'Yaku Prince' can be grown in a container as it is one of the more compact smaller growing rhododendrons. Many do not recommend planting rhododendrons in pots but I think this is mainly due to their shallow wide root system. Planted in pots the shallow root system is more apt to dry out or be subjected to saturation by poorly draining soil.
The rhododendron must be planted in a loose and porous soil mix that is well draining. Rhododentrons are no different than growing azaleas and camelias in containers. As long as the soil in the pot is kept moist not wet or dry you should have no problems growing them in pots. No matter what pot you chose it should never be located where it is not protected from any hot afternoon sun. In most locations rhododendrons need protection from direct hot afternoon sun anyways. Your better nurseries and garden centers will carry quality planting soil mixes for these types of plants (Rhododendron, Azalea, Camelia) needing good drainage and more acidic soils. I personally never buy my planting mixes from the large box stores as I have never found a quality product that will stay well draining and not become broken down into sluge within a year. Be sure whatever container or pot you choose it has plenty of drainage holes in the bottom.
As far as surviving the winter this would depend on your locations hardiness zone. The 'Yaku Prince' Rhododendron is cold hardy to zone 5 but in a container you would take away one zone (now zone 6) unless you can move the container to a more protected area for the winter or wrap the container well with burlap or blanket of some kind to keep the roots from damage from freezing temperatures. The plants in containers is of course more suseptable to heating and freezing than if planted in the ground. You can find your hardiness zone by clicking on Hardiness Zones in the upper right corner of any page in Gardenality. If you give me your city and state I can look it up for you.
Hopefully this has answered your question. Please ask if you have any others.
