Hosta ‘Krossa Regal’

1974 Eunice Fisher Award Winner.
2001 AHS Alex J. Summers Distinguished Merit Hosta Award
2008 AHS Benedict Garden Performance Award of Merit
2006 AHS Benedict Garden Performance Honorable Mention Award

Hosta ‘Krossa Regal’ was brought to America from Japan by Gus Krossa. It was registered with the American Hosta Society in 1980. Some information says it was registered by Alex Summers others say by his wife, Alma, after his death.  If I remember correctly, I once read the plant was given to Alex Summers by Gus who then registered it.

Information from The Hosta Helper says The Hostapedia by Mark Zillis states that it “was registered as a sterile offspring go H. nigrescens… more likely a hybrid of H. rectifolia x H. nigrescens or H. rectifolia x ’Tokudama’…”

There are 23 registered sports of Hosta ‘Krossa ‘Regal’ and three registered hybrids with it as a parent. One of its most famous sports, Hosta ‘Regal Splendor’, was registered by Walters Gardens in 1987 and was the 2003 American Hosta Growers Association Hosta of the Year. It also received the American Hosta Society Benedict Garden Performance Award of Merit.

I bought my first Hosta ‘Krossa Regal’ from Bluestone Perennials in the early 1980’s when I first moved to my grandparent’s farm after my grandfather passed away. After I left in 1987, my father was left to mowing the yard and eventually mowed off the Hosta. Then, when I was living at the mansion in Mississippi, I bought another Hosta ‘Krossa Regal’ from an Ebay seller in 2009. I sold the mansion to a group who wanted to turn the mansion into a bed and breakfast and dad wanted me to return to the family farm. So, in February 2013, I gave away around 200 plants and moved back to the family farm that I had left in 1987. I brought most of my succulents, Colocasia and Alocasia, several perennials including my Hosta, and several other plants I couldn’t leave behind.

The Hosta ‘Krossa Regal’ managed to do fairly well in Mississippi while most of the others just “hang in there”. None of the Hosta flowered in Mississippi for some strange reason.

In the 1980’s I had made a Hosta bed along the northeast corner of my grandparents home. The house is no longer there, so when I moved back in 2013, I had to do something else. I had also built a bed around grandma’s old goldfish pool which was now shaded by three large trees that weren’t there before. So, I dug a spot there for my Hosta and Ajuga reptans ‘Chocolate Chips’ I brought with me from Mississippi. The gold flowered Iris I had planted in the early 1980’s were still there!

Hosta ‘Krossa Regal’ caught my eye in in 1981 because Bluestone’s information stated it grew to over 36″ tall and had flower stems up to 6′ tall. Well, back then as now, I like really BIG plants. So, I had to have one of course. Hosta ‘Krossa Regal’ has other distinguishing features such as their vase-shaped growth habit and powdery blue-green leaves.

Hosta ‘Krossa Regal’ has thick leaves which make is very slug and snail resistant. I don’t have any problems with either one here, but I did have some problems in Mississippi. This is important to know for you if you have slug and snail problems.

FINALLY in 2013 after several years, my Hosta ‘Krossa Regal’ flowered!


Hosta ‘Krossa Regal’ on 8-14-13, #174-12.

It seemed like forever watching the stem grow taller and taller.

I will let you know right now, if you expect a 36″ tall plant within a couple of years, you will just have to be more patient. Although H. ‘Krossa Regal’ MAY ultimately reach that size, it will take some time. So, don’t do as I did and plant it at the back of the bed with other cultivars that will grow large faster. They will overshadow your ‘Krossa Regal’.

Even though I really like this plant, I take a lot of photos during the summer and am running out of words…

No doubt if you grow Hosta ‘Krossa Regal’, you will admire it for its graceful growing habit. While other Hosta cultivars leaves grow this way and that, this plant seems to perfectly position it leaves with a definite plan.

As always, spring is an exciting time of the year. Waiting with anticipation all winter to see what has survived and what hasn’t is a real killer. It is always great to see the first sign of the Hosta emerging from their winter hibernation.


Hosta ‘Krossa Regal’ on 4-9-15, #236-8.

It is always nice to see the clumps get larger with each year. It makes you feel you have done it right.

During 2016 it appeared to me there was a problem… It seemed as though the clump of ‘Krossa Regal’ were getting crowded out. You can’t see it in this photo, but in front to the right is the every growing Hosta sieboldiana ‘Elegans. To the left is Hosta ‘Red October’ (in the front of the bed) and Hosta ‘Guacamole’ on the back corner.


Hosta ‘Krossa Regal’ on 4-20-17, #320-5.

Well, I knew something needed to be done for sure because Hosta ‘Krossa Regal’ was far more deserving than to be crowded out on the back row…

So, I dug a spot at the end of grandmas’ old goldfish pool. Originally, back in 1891, I had made a brick sidewalk all the way around the fish pool. I had to dig up the bricks, which somehow got buried under several inches of dirt. I moved the Hosta ‘Krossa Regal’ and was happy to find it had spread. Yeah, I know! I am supposed to put them farther apart… I could have left them in one big clump but I decided to separate them a little. Later, I bought a beautiful Hosta ‘Dancing Queen’, my first yellow-gold leaved Hosta! They made great companions. I also moved the Heuchera ‘Palace Purple’ to this spot because it was also having difficulties.


Hosta ‘Krossa Regal’ on 6-18-17, #345-28.

Apparently, the Hosta ‘Krossa Regal’ approved of the change. It looks so happy now!

The grassy looking plants in the background are Iris fulva I brought back from Mississippi. 🙂

The big white leaf if from another new addition. Caladium ‘Strawberry Fields’.

As cooler weather approached many of the Hosta are showing signs of winter hibernation. The Hosta Krossa Regal’ had a good summer and I hope it returns in the spring. The Caladium ‘Strawberry Fields’ was definitely a show stopper, but it was one of the first to go dormant. I saved the bulbs!
