We are always asked by hosta fanatics what varieties they can grow in full sun. Although the ideal conditions for hostas are shady and damp there are some varieties that can perform very well when planted in a sunny spot. We would usually recommend that you aim to grow your hostas in partial shade but if you do choose to plant in a sunny position here are a few ideas of varieties you can use.
(Hosta 'Sun Power' grown in full sun)
Hosta 'Sun Power' is a great example of how some varieties are better in the sun. 'Sun Power' has bright golden leaves and forms an impress mound at full size. Usually best to plant in the ground as apposed to a pot as 'Sun Power' is a large variety that needs space.
If grown in the shade 'Sun Power' stays a chartreuse green and does not get as bright and yellow as it would in the sun.
(Hosta plantaginea 'Aphrodite')
Hosta plantaginea 'Aphrodite' is another varieties that needs plenty of sun. It especially needs this to produce it's beautiful fragrant flowers. If planted in an overly shaded position 'Aphrodite' would not produce as many flowers which are one of the main attributes of the variety.
Plant in a position that gets full some for part of the day, this way you will get the beautiful flowers without the leaves burning to early in the season.
(Hosta 'Sum and Substance' mid Spring)
Much like hosta 'Sun Power' the beautiful hosta 'Sum and Substance' is a great grower in full sun. It's large chartreuse leaves turn brighter throughout the Spring and Summer, in the shade this would be a much slower process and by Autumn the leaves would still not get to the bright gold they would be if grown in the Sun.
'Sum and Substance' is an extremely popular hosta due to the fact it is versatile, easy to grow and a show stopper in the garden!
Always remember, hostas in full sun will require more watering then hostas in the shade especially in their first year.
