The yellow in a hosta is a genetic absence of chlorophyll, which makes the leaves appear different shades of yellow. As yellow hostas contain fewer food-producing chloroplasts, annual fertilizing is important.  (Note: Around 2003, the American Hosta Society changed its show terminology from “gold-leafed” to “yellow-leafed.”  Chartreuse hostas are considered to be in the green category.)

Yellow Hostas Need More Sun

As a general rule, a yellow hosta needs to be planted in a sunnier location to keep its color vibrant.  The yellow color may fade to green without at least two hours of full sun daily. Some glossy, chartreuse hostas change to yellow when exposed to more light, like H. ‘Sum and Substance.’ Yellow or yellow-centered hostas are often sun-resistant.

The temperature of a full-sun area can vary by the time of day and by your location (southern versus northern United States, high altitude versus low altitude).  Even though yellow hostas need some sun exposure, any hosta in full sun will need to be watered frequently.  Overhead watering during the middle of the day can cause water droplets to magnify the sun’s rays and burn the leaves.  Hostas grown in full sun will often turn to a lighter color and the leaves can elongate.  Yellow hostas are most vulnerable to sun damage early in the season when the leaves are expanding.  This is when trees have not gotten all of their leaves back yet.

Using Yellow Hostas in the Garden

Yellow hostas add color, brightness and contrast to the garden.  Their luminescent leaves glow at dusk, dawn or on rainy or overcast days.   Planting next to green or blue foliage makes all of the different colors stand out.  However, over-planting yellow hostas in a blue or green border can produce a spotty effect

How the sun affects a hosta


Deep Shade
:
Hostas do need some light! If you place them in too much shade they will eventually shrink and then die. It is hard to quantify shade so you may need to experiment by trying the hosta in your desired area and observing it to see if it grows well. Keep in mind, all perennials, including hostas, sleep the first year, creep the second year and then leap the third year in terms of growth. Hostas with the most chlorophyl (plants with lots of green or blue in them – not color or white) do best in deeper shade.

Full Sun: Plants rated as Sun Resistant (you can see ratings on our web site) mean that these hostas will do better than other hostas in full sun. Many hostas in full sun will eventually burn on the edges or even the centers, bleach, and elongate, turning into a football shape. The sun resistant hostas are most apt not to do that. I have grown hostas in full sun, on a steep slope and with little water and it grows and looks well. I don’t recommend you do this but just using this as an illustration.
