Aucuba Japonicas in the Home Garden

It has been quite a while since I first posted about Aucuba japonica (Aucuba japonica), aka Gold Dust Plant, so I thought I'd take the time to talk about this favored shrub of mine here in Tiger Gardens. Winter is sometimes when the aucubas shine the most in the garden so right now, early February, is the time to spotlight this wonderfully adaptable shrub.

We'll first start with a description which will include glossy evergreen leaves speckled and splashed with dots of yellow. It is almost as if someone took a paintbrush and flicked specks of yellow paint all over this deep evergreen shrub. The shrub will stay a neat and rounded shape that will very slowly grow to about six feet or more in the home garden. My aucubas have been in place about eight years and have finally reached the very large size of four feet tall and about 3 1/2-4' wide.

Aucubas begin producing buds in the winter. Soon these buds will open up and bloom. If there is a male shrub nearby and the buds on a female aucuba are pollinated you will be overjoyed to see berries growing on your aucubas. The berries have not yet formed on these shrubs this year but if you'd like to see what they will look like take a quick peek at my first aucuba post found here. It is absolutely necessary to have a male plant along with female plants if you want berries on your aucubas. At many reputable and good quality nurseries you should be about to find aucubas sexed-labeled male or female. Big box stores may or may not have their aucubas labeled as to male or female so be aware that when you purchase an aucuba you need both a boy and a girl in order to have berries. If, however, you only wish to propagate the aucubas they can be rooted easily from cuttings so you don't need the berries to make more.

Aucubas fit into woodland and shade gardens marvelously. I have mine all planted in a raised bed surrounding a large short pitch pine located in the front yard. There is also a nearby Pieris (Pieris japonica 'Mountain Fire'). Both of these shrubs grow in a good organic soil that is heavily mulched with pine needles from the pine tree each year. The garden is extremely dry during the summertime so I occasionally have to water-but you must be very careful when watering aucubas. It is better not to water them than to water too often too shallowly. I think I watered these aucubas only one time last summer from early May until late June. Most of the other plants and shrubs in my garden required far more water. Be sure you give aucubas and pieris a good well drained area in which to grow or they will suffer. Both pieris and the aucubas need some sun protection and will burn if not given sun protection. Pieris and aucubas are shrubs for the shade.


My aucubas help to provide a great deal of privacy from the road in front of my home. Evergreen shrubs are good for that as well as for looking great in the wintertime. The above picture was taken looking toward the silverberries and road. I wanted you all to see just how full and lush the aucubas are during this time of the year. It wasn't until I uploaded these pictures that I saw the little female cardinal sitting in the hedge on a crepe myrtle branch. Can you see her?

If not, here is an up close picture of the cardinal enjoying the view of the aucubas....

Aucuba Japonica

Living in the south makes one really appreciate the shade. Oh boy do I ever appreciate shade! As much as I love the shade, I bemoan the fact there are not as many colorful plants for the shade as there are for the sun. There are a few though, and the one I wish to talk about today is the Aucuba japonica.

When I first moved here in 2001, I kind of went on a buying spree. Any new plant was fair game. Some worked well, some did not. The ones that worked well I made a mental note to get more of them and to learn more about them. Aucuba japonica, aka the Gold Dust plant, certainly fit in the category of 'shrubs that do well in the shade'. Not only do they do well in shade, but they do just fine in dry soil too. Good thing since most of our summers are quite dry, and most of my shade is dry too.

The aucuba pictured is one of about 1/2 dozen aucubas growing in my garden. They are all planted in a raised bed out front that encircles an oak tree and a very mature pine tree. You can just make out another aucuba directly behind the one featured today. I featured this particular one because it is a female aucuba. And female aucubas bear bright red berries! See them in the first picture? What a lovely sight on a winter-make that a spring day.

In order to get berries on the female plant, you must have a nearby male plant. Now how on earth can I or anyone determine what is a male aucuba and what is a female aucuba? I guess by the luck of the draw I managed to purchase a male somewhere along the way, along with the females. This is the first year in many years that the aucubas have borne a great amount of berries. By great amount, I mean more than 5 or 6. Not many really, but the few that do show up are welcomed.

Many gardeners do not realize that aucubas are not self pollinating. I can tell you from experience it is difficult to find an aucuba that is marked 'female' or 'male' in nurseries or big box stores. Sometimes you can occasionally find a male cultivar that is usually variously labeled with a 'Mister' in its name, but not often. The best advice I can give is to make sure you have more than one aucuba and buy from a variety of sources, or even better, find a nursery that understands aucubas need a male and female in order to produce berries.

I planted these aucubas around my one and only pine tree out front. They circle the pine tree and the intent is for the aucubas to grow large enough that they completely encircle the trunk so it looks kind of like the trunk is growing out of the aucubas. I like that effect and aucubas can grow up to 15 feet, though 6-8 feet is more common in gardens. I expect they'll do fine here and continue to grow in order to produce the effect I hope for.

The fact the aucubas are evergreen is a bonus that helps to shield our home from a busy state highway. This time of year aucubas can get some freeze damage and the tips of their leaves will turn black and dry up. Not to worry, once warm weather arrives they will bounce back beautifully.

Aucubas would prefer a moist well drained soil slightly acidic to be in ideal conditions, but is adaptable. The fact mine are planted under a mature pine should tell you the difficult growing conditions these aucubas are growing in. The soil is extremely dry and rather congested with pine roots, however the aucubas are undaunted, and still they grow.

All parts of aucubas are poisonous. This is very good news if you have a deer or rabbit problem, but you want to site these shrubs carefully while keeping this fact in mind if you have children or pets around who may eat the shrubs.

So, here is a wonderful shrub with colorful leaves and red berries that can brighten any shade garden in the south. Their growing zones only include 6-10. That must be the reason I could never find them up north, but here they are fairly abundant under shade trees, keeping me cool and providing color.
