Can Heuchera Tolerate Sun?

Gardeners who want to plant in their garden heucheras often ask whether heuchera will withstand direct sunlight? Such curiosity is quite understandable because not everyone has enough shady places in the yard. Still, the varieties of these beautiful plants a vast number, and all of them want to place somewhere.

Heuchera can tolerate partial and full sun, but here are some features to consider. First of all, not all varieties can grow in full sun. Also, to grow in a sunny place will need to give the plant a little more attention.

To quickly find out how much light the variety can take, I created a table. It has three columns; the first is the name, the second, and the third is the amount of sunlight. It has the most popular heucheras; we will talk about the others in more detail later.

Name Partial Sun Full Sun
Plum Pudding tolerate tolerate
Palace Purple tolerate tolerate
Chocolate Ruffles tolerate tolerate
Frosted Violet tolerate tolerate
Pewter Veil tolerate tolerate
Gold Strike tolerate
Lime Marmalade tolerate
Pistache tolerate
Northern Exposure Lime tolerate
Lemon tolerate

As the table shows, not all varieties can withstand a full sunny day. Let’s define what is full and what is the partial sun.

Full sun means that the plant grows n a place where direct sunlight falls during the day. The time during which this occurs is approximately 8-10 hours, depending on the time of year. It means that heuchera takes sunlight at all without even a partial shade throughout the daylight hours.

Before the beginning of growing these plants, I had doubts that this is possible because everywhere they wrote that they needed shade, etc. After several years of practice, it can be said that they can grow in the sun.

However, here you need to clarify, if you live in the southern states, then plant Coral bells in a place where it will receive direct sunlight from morning to evening is not worth it. It should be limited; the plant should receive no more than 10 hours of sun.

Partial sun means that the plant receives direct sunlight for several hours a day. The important thing here is that the heuchera does not get direct sun in the middle of the day when it shines the most. To achieve this, you can plant a heuchera near the west or east side of the house, and as a result, direct sunlight will fall on the plant only half a day.

You can also plant it on the side of a tall plant (tree) or near a fence. As a result, heuchera will be shaded by half.

As a rule, the darker the color, the more resistant to sunlight heuchera is. In such conditions, it will even have bright leaves and will be thicker. Let’s look at some popular varieties that are great for sunny places.

Peach Flambe is a compact heuchera; it can grow in a sunny place. I have one too, but mine grows in shadow. In one of my friends, this variety grows in the sun and does not burn, so you can safely plant it anywhere.

Cajun Fire has large leaves of red color, due to its color, it can take a lot of sun. The shape of the leaves is unique, grows energetically. Soon enough, it forms a large bush, so it needs a lot of space.

Rio has a beautiful pattern on the leaf; the color is bright red. The bush is very neat and elegant. In my garden also grows this variety, it takes 6-7 hours of sun a day, and so far, there were no problems with it.

Peach Melba is a pink variety with medium leaf size. It can grow both in the sun and in partial shade. Several collectors have told me that this heuchera grows many years in their garden without shadow, and everything is fine with these plants.

Obsidian is a trendy variety, and I have one too. It has large leaves, almost black. Young leaves have a burgundy color; the surface is shiny. I have this variety; it grows in full sun and never burned. It is one of the most sun-resistant heucheras.

Heucheras that can take partial sun

The least resistant to the sun varieties that have a light or yellow color of the leaves. Next, we look at some common types that are not worth planting in full sun.

Yellowstone Falls is a weeping variety; its yellow leaves can take no more than 4 hours of direct sunlight. My Yellowstone Falls grows in the shade; as a result, the middle of the leaves is not very bright. As experienced collectors say, if you plant this variety in a place where there will be several hours of direct sunshine, it will be very bright.

Solar Power is one of the best yellow-green varieties, in partial sunlight has a unique color of leaves. However, with plenty of sunlight, it will burn. The variety grows quickly, so when planting, it needs to allocate more space.

Rex Lime is an energetic variety, with light green leaves, leaf shape twisted. Unfortunately, in high light, the leaves get burned, so put it in partial shade, it is better than the plant is protected from the midday sun.

Lime Ruffles is a rare cultivar with twisted yellow-green leaves. I don’t have one, but an acquaintance of mine told me that he planted this variety on the south side of the house, and after a month, the leaves were very burned.

Lime Rickey is better to grow in a place where the morning sun shines, so it will have brighter leaves with a lemon tint. It will be green in full shade. In full sun will receive burns of leaves. The variety is quite compact and sophisticated.

The successful growing of Coral Bells in the sun

For the heuchera to grow in the sun, it must be well watered. This is the most important condition, and if you ignore it, you can harm your plants.

Automatic irrigation is best for this, but manual watering will also be suitable. It is necessary to water quite often, especially in dry weather. The soil around the plant should be constantly moist, but it is not necessary to overwater it.

According to experienced gardeners, a small amount of fertilizer for heuchera promotes better growth in the sun. Thanks to the feeding, the plant begins to grow more intensively and removes more moisture from the soil, which allows it to take more sun.

Good soil is also a necessary condition for your heucheras to feel comfortable in the sun. It is best that the ground holds enough water but that the water does not stagnate. It will also be useful if the soil is nutritious.

In case your heuchera cannot withstand the sun, you have two options—the first to transplant it into a more shaded place. However, not everyone has enough dark areas in the yard. Therefore, the second option is suitable for you.

The second is to shade the plant from direct sunlight in the middle of the day. For this, you can build a shade in front of heuchera from a mesh material.

Here are all the conditions through which you can grow your Coral Bells in full sun. Next, I will answer some common questions related to this topic.
