The topic of this article is very exciting because the giant hosta is probably the most unusual garden plant. Here you will find many interesting varieties and a lot of other useful information.
Giant green hostas
Let’s start with the most numerous group – the giant green hosta. Although the color of their leaves is not as unusual as the others, they are nevertheless worth your attention.
Empress Wu Hosta
First on the list is Empress Wu because of its enormous popularity. Everyone who is even a little bit interested in hostas must have heard about this wonderful variety.
It is truly a giant hosta because it reaches about 3 feet tall and 7 feet wide. It will take at least five years to get to that size.
The leaves are round and very large. The color is dark green and very intense.
This hosta needs a lot of space and nutritious soil.
T-Rex is the next huge variety of hosta that will amaze you with its leaves. They are so huge that they hang down a little under their own weight. In addition, the leaf margin is slightly wavy, which is an additional ornamental advantage.
The T-Rex can reach a width of six feet or more. At the same time, the height is usually up to 3 feet. After a few years of growing, you will have a huge mound of large leaves.
This variety needs a nutritious and light substrate to reach its maximum size. You also need to water and feed it often.
Minke is a green large hosta that has some features. First, its leaves have a slightly bluish tint at the beginning of the season, but then they turn green. Second, the edge of the leaf is colored light yellow. These differences make it very interesting compared to other varieties.
This variety can grow up to 3 feet tall and 5 feet wide. To get a bush of this size you need to provide it with plenty of nutrition, water, and loose soil.
However, don’t expect it to reach its maximum size in one season. You will have to care for it for several years.
Lothar The Giant Hosta
The huge leaves of Lothar the Giant can surprise even the most sophisticated gardener. The leaf blade can reach up to 14 inches long! At the same time, it is about 10 inches wide. In addition, the leaf edge is slightly wavy, which makes the hosta even more unusual.
Its slight disadvantage is its slow growth rate. It will take the Lothar the Giant at least five to six years to reach its maximum size (3 feet tall and 6 feet wide).
The color of the leaves is dark green, which looks great in combination with the ribbed texture.
This variety, like all hostas, needs full or partial shade and adequate watering.

What is the largest variety of hosta?
The largest hosta in the world is the Giantland Big Bastard Hosta. In the picture, you can see the originator of this variety, Jeff Miller, with his creation. The leaves of this hosta reach 2.5 feet long and 1.5 feet wide! This is certainly a record at the time of this writing.
In addition, the height of this hosta exceeds 3 feet. As for the width, it is too early to draw any conclusions because Giantland Big Bastard Hosta is a new variety. One thing is for sure, however, that at maturity it is capable of reaching 10 feet wide or even more.
Jeff Miller is the founder and owner of Land of the Giants Hosta Farm. This nursery specializes specifically in the breeding of giant hostas, so we should no doubt expect even larger varieties in the near future.
How to grow giant hostas?
To successfully grow giant hostas, the first thing is to provide them with good soil. Dig a hole at least 3 feet wide and deep.
Mix the resulting soil with compost or soil conditioner. Plant the hosta in this substrate so that the petioles are not submerged in the soil.
Water the hosta with 2 to 3 gallons of water. Then constantly check the substrate for moisture. If it is more than an inch dry, water the hosta. A giant hosta uses a lot of water, so water often, but avoid overwatering.
Fertilize the hosta at least once a season in early spring. Use a slow-release multi-purpose fertilizer. After flowering, fertilize the hosta with liquid fertilizer. Avoid fertilizing later than July.
To grow quickly but not get burnt, the hosta should grow in partial shade. Plant it in a location with up to 4 hours of morning sun per day. But this does not apply to giant blue hostas, they should grow in full or dappled shade.
How to divide a giant hosta?
Divide a giant hosta in the same way as any other hosta. Simply dig it out of the ground and cut it into several pieces. Each part should have at least three eyes.
You can also divide a large hosta without digging it up. Cut it up into pieces with a spade and plant it in other places. Treat the wounds with crushed wood ash or spray with fungicide.
However, if you want a truly gigantic hosta, you should never split it up at all. Plant it where there is plenty of space. Fertilize and water it, and gradually make more and more room.
In five years at the earliest, the hosta can reach its maximum size. If you don’t split it up and replant it for at least 10 years, you will get a really enormous plant.
