Hebes for Northwest Gardens

Hebes are small evergreen shrubs from New Zealand. There are around a 100 species and about 750 cultivars. With so many species they cover a wide array of terrain and climates. In Oregon I have had the best luck with species from the cooler South Island of New Zealand. I am basing this advice off of personal experience. I keep close tabs on the hebes at my house, Joy Creek, and all around the Portland area. They grow wonderfully along the Oregon and Washington Coast and through the Puget Sound basin. I want to first look at what to look for in a plant, then go through growing conditions, and finish with the most common question, “How do I keep this alive?”

The main attraction of hebes for me is their evergreen foliage. The variety of leaf sizes and shapes is incredible. When dealing with hardiness, generally the smaller the leaf, the hardier the plant. It has also been found that hebes with gray leaves tend to survive drought better than others. Some hebes have foliage that changes color in the colder months to provide further winter interest.

The red foliage darkens in winter.

I tend to view bloom as secondary when growing hebes in the yard. This is because when chasing the showiest bloom you tend to lose hardiness. Many hardy hebes do bloom profusely but they tend to be smaller

Growing Conditions:

Sun- Grow in full sun to open shade. Hebes do well in deciduous shade so that they can get sun in the winter but dappled light in the summer. When grown in too much shade they tend to get leggy and one sided as and stretch toward the light.

Soil- Any decent semi well drained soil will do. I have not found them to be too picky as long as they are not underwater. They do grow much quicker in well amended soil.

I have a downspout that empties onto this all winter and it has put up with it. I would not recommend this, but it still hasn't killed the plant.

Water- Hebes are not excessively drought tolerant on the whole. Certain varieties are more tolerant that than others, but most like bi-weekly water during the summer. When grown in part shade you can get away with a lot less water. Whipchord types are less drought tolerant than others.

Pruning- Cut out dead material after heavy frosts are past. Prune for shape in early spring and give some fertilizer or compost after to feed new growth. Though this might reduce flowering in certain varieties, I don’t want to risk late season due to the likelihood of young growth being damaged in the winter.

Propagation- Hebes root very easily from cuttings. Take semi-hardwood cuttings in August to October. Leave two nodes on top and one below soil level. They can also be rooted in water. This is a great way to protect against winter losses. They can also be done through layering.

Pests and Disease- Some deer eat hebes and some do not. They are currently one of their favorites at Joy Creek. Septoria leaf spot (black spots on the leaves) is more of a problem in nursery settings than the garden. I would accept a little on a plant I purchase, but avoid anything that is too ugly.

Tips to Keep Your Hebe Alive;

1.Pick the right one. Some cultivars seem to croak every year while other similar looking ones just keep on trucking.

2. Plant in the spring. This allows the plant to establish before winter but this also means you have to water the first summer.

3.Give all hebes some water when it hasn’t rained in months. A good deep soak goes a long way. They are from New Zealand, not the Mediterranean. I admit to babying mine a little, but there is a difference between surviving and looking good.

4. Site your plant where it is protected from cold winds. The Arctic blast coming down the gorge is death for hebes. It dries out the fleshy evergreen foliage and they cannot survive. Plant next to wind breaks or on the west side of tree, hedge, or house. Salty ocean breeze does not seem to effect them. You can grow all the hebes you want at the coast.

I kept this alive by planting it out of the wind on the west side of my house.  It survived 12 degrees with a little help from a garbage can.

5. When it gets cold quickly in November and early December give them a little extra protection from a bucket or fir boughs. Once they have been through a good frost they are unlikely to get damaged unless it is below 15 degrees. Give the same protection if there is a late frost. They often just need to be a little warmer and out of the wind. A little protection goes a long way.

Don’t give up on hebes just because one died on you, there are great ones out there.

An Interview with Andy Stockton about Hebes

I have posted a few interviews for upcoming classes over the years and wanted to do one for the class this Sunday, June 28th. It happens to be me teaching the class, so I think this interview should go smoothly.

When did you first learn about Hebes?

It was when I started at Joy Creek Nursery in 2007. I was put in charge of arranging and restocking the shrub section. At the time we already had a large hebe inventory and they sucked me in more than any other shrub. There had been a series of mild winters and there were a number of beautiful established hebes in the garden.

Frost accentuates the pattern of the leaves.

Can you say why they intrigued you so much? Was it just their name?

Hebe is a fun word to say, I can’t deny it. I think what drew me in was the textures of the foliage. The leaves have a geometric pattern that is not as apparent in most other plants. It is more something that you notice up close. Every single one has the same alternate opposite leaf pattern no matter how large or small the leaf. There is such a wide variety in looks and sizes throughout the genus that it is fascinating they are all related.

Has your opinions about hebes changed over the years?

After my first year at Joy Creek I really liked hebes, but we had a incredibly cold winter that year. Many of the hebes in the garden were killed. We then had two more hard winters after that. Many of the showy hebes at the nursery died and customers grew very weary of buying them. I still have a soft spot for all of them, but I have gotten much more careful about which ones I recommend. Many of them are going to die without protection. I have accepted that.

Hebe corrigani march bloom smHow many Hebes do you currently grow at your house?

I have 76 different forms and 103 total in my yard.

Too many?

Never enough.

How many hebes have you killed?

So so many… It is all research right?

Two years ago Joy Creek introduced Hebe ‘Dragonfly’, your first introduction. How did that come about?

I found the original group of 5 seedlings in a flat of euonymus at the nursery 5 years ago. I potted them up, after asking of course, and took them home to see what they would do. After a year in containers I planted each one out in the yard. I do not know the specific parentage of the seedlings but each one was quite different. After a year in the yard I took cuttings of my two favorite and we raised them at the nursery to see how they would look. Hebe seedling #2 ‘long leaf’ was deemed the most unique of the two and chosen for introduction. The leaves reminded me of a dragonfly and that is how it got its name. I have 3 more seedlings that we are trailing to see wether they are good enough to release.

Thank you for taking time out of your busy afternoon of talking about plants and petting Yowler.

It was my pleasure, and I still had plenty of time for petting a kitty.
