Rainy Side Notes

The seven sons tree (Heptacodium miconioides) was named a Great Plant Pick for 2008. I heartily agree this is a choice plant for the Pacific Northwest. It certainly is one of my favorite, easy to grow, large shrubs. I first bought mine over 10 years ago and couldn't find any cultural advice on how to grow it. Unfortunately, this shrub isn't drought tolerant so it needs supplemental watering during our annual drought period.

I pruned my plant to a single trunk so it appears to be a small tree, instead of a large shrub. At its base, I planted Clematis 'The President'; the vine climbs into the branches and flowers in spring and again in summer, giving the shrub another season of interest. In the fall, red calyxes follow the fragrant, creamy white flowers born in clusters of seven, that bloom in late summer. The leaves turn a decorous purple-bronze hue in fall.

The genus was first collected in 1907 by by E.H. Wilson in Hupei Province, China. Afred Rehder from the Arnold Arboretum described the new genus in 1916. Rehder named the collected specimens hepta, which means seven, and codium, which refers to the flower head. It then was forgotten until1980, when it was rediscovered by the Sino-American Botanic Expedition.

Recently introduced to this country by the Arnold Arboretum and U.S. National Arboretum, this beautiful multi-stemmed shrub or small tree is not bothered by pests or diseases! H. miconioides is rare in China, with few if any to be found growing in the wild anymore. The shrub has tan bark that exfoliates to reveal an attractive brown inner bark. In August, the white buds form, and in September, the flowers open with a fragrance of jasmine. In fall, the calyx turns bright red until the first hard frost. In a good year, the shrub turns red from numerous calyxes. This is a great shrub for late summer, fall and winter interest. Another plus for this shrub is its salt tolerance, so it could be used near the seashore. It also attracts butterflies.

The Amazing Seven Sons Flower

1aaaheptacodium101

At this time of the year, it’s difficult to find floral fragrance in the garden. Fall is mostly about the smell of the earth, the dried leaves and pine needles, always more pungent than sweet. There are, however, a few plants and trees that offer one final whiff of sweet perfume, starting with this seven sons flower – Heptacodium miconioides.

It is also less-commonly referred to as the Autumn lilac – a name I love for its Spring-like connotation. The fragrance of the seven sons flower is indeed sweet, if a little lighter and less pervasive than a lilac – but on slightly breezy days it can carry on the wind.

When caught, the scent is always a surprise – the flowers are so unassuming (these are extreme close-ups), and you simply don’t expect this sort of fragrance in the garden right now. Also of note is the graceful yet rustic way its bark peels. The trees I have are about three years old, and this magical process is just starting on them. The mottled bark that is revealed is the main reason this plant caught my eye at the nursery.

One final note of whimsy – the bees absolutely love these flowers,  but instead of inducing a frenzy, the blossoms seem to get them drunk, to the point where they are literally falling over themselves in mid-air, stumbling from bloom to bloom in a sedated state of giddiness. You can’t help but love a plant that offers beauty, fragrance, bark, and intoxication.

Propagate Your Shrubs from Softwood Cuttings

With the right tools and conditions, it's easy to propagate new plants from softwood shoots

 

 

 

These hydrangea cuttings should form roots in less than six weeks.

I have propagated thousands of new shrubs from softwood cuttings. That may sound like a lot, but since I'm a propagator at a nursery, it's all in a day's work. To successfully propagate such a large number of shrubs requires specially designed hoop houses and state-of-the-art misting and heating systems. It's also handy to have helpers to carefully monitor the health and well-being of each cutting.

On a smaller scale, though, it is possible to propagate deciduous shrubs from cuttings taken during the summer without the all the high-tech machinery and costly gadgets I have at the nursery. By creating favorable conditions, using the right tools, which are actually quite simple, and being patient, you can achieve success with softwood cuttings at home, too.

Harvest cuttings from semi-ripe growth

The trickiest part of propagating shrubs from softwood cuttings is knowing when a shrub's stems are ready to be cut. Softwood, the section of a shrub's stem that's neither brand new nor fully mature, is the stage of growth on a deciduous woody plant that is best suited for rooting (for details, see Softwood is neither green nor woody, below). The newer, green growth that lies at the end of the stem will rot before roots are produced, and the older, more woody growth at the base of the stem has a harder time putting out roots.

Softwood cuttings can be taken from most deciduous shrubs in June and July and sometimes into early August. I determine a stem's maturity by taking it in my hand and bending it. If the stem breaks with a characteristic snapping sound, it is in the softwood stage and ready to be harvested as a cutting. If the stem is still too green, it will bend but not break. If the stem is entering the woody stage, it won't bend at all.

 
 Softwood is neither green nor woody

Softwood is the term used to describe the stage of growth on a deciduous woody plant that's neither the new, green growth at the end of a shoot nor the stiff, woody growth near the base of the stem. The softwood lies between the two. The best way to know if a shoot has reached the softwood stage is to bend it. If the softwood snaps, the shoot is ready to be taken as a cutting. If the shoot is very flexible and doesn't snap, it's too green. If the shoot is not flexible at all, it is too far gone.

The best time to take cuttings is early in the day, when shoots are fully hydrated. Lateral shoots, or those that grow from a leader, make the best cuttings. I avoid weak, thin shoots, as well as overly thick, heavy ones. As soon as I take a cutting, I nestle it into a plastic basin that I've filled with damp paper towels. The towels will keep my cuttings moist and cool until I'm ready to head back inside and pot them up. They also shade my cuttings from the sun. Exposure to direct sunlight, even for only a few minutes, can cause irreparable damage. I also avoid taking cuttings on hot days, when plants may be wilting.

 1. The best way to test if a stem has reached the softwood stage is to bend it. If it snaps, it's ready to be cut.
 

 

 

2. Cut a stem about one inch below the second leaf node. A cutting should measure between 3 and 5 inches. 

 

Keep cutting short to conserve energy

A cutting's size is also something to consider. I like my cuttings to contain at least two sets of leaves. I use pruning shears to cut the stem from the shrub at about one inch below the second leaf node. Since the length between leaf nodes differs from plant to plant, the size of a cutting, using this rule of measurement, will vary. The average cutting should measure between 3 and 5 inches.

To prepare my cuttings for rooting, I remove the lower set of leaves to open up wounds on the shoot. It is at these wounded sites that rooting will occur. I also wound the end of the shoot's tip by laying the cutting on its side and shaving away a strip or two of bark.

 

  

3. Keep your cuttings cool and moist while collecting them. The author uses a plastic basin and moist paper towels to keep her cuttings fresh.
 

  

4. Remove leaves to create wounds. The wounds allow the rooting hormone to can gain entry into the stem.

Use rooting hormone and provide good drainage

After I've wounded the cutting, I dip the end of the stem into water and then into rooting hormone powder. Softwood cuttings root more successfully when a rooting hormone is used. The object when dipping cuttings in rooting hormone is to cover the wounds completely. Rooting hormone contains the same auxins already in the stem that initiate root production. Coating the stem with hormone boosts the plants' natural mechanisms to produce roots.

I'm careful never to dip cuttings directly into a jar of rooting hormone powder for fear that the cutting may contain a contaminant. To be on the safe side, I empty a small amount of the hormone into another container and dip my cuttings into that.

Once a cutting's wounds are coated with rooting hormone, I gently tap off any excess and insert the stem into a six-pack or seedling tray filled with a moistened mixture of perlite and soilless mix. The potting mixture we use at the nursery is 60 percent perlite and 40 percent soilless mix. This mix provides the good drainage and maximum aeration that new roots need. Cuttings placed into a mix that holds moisture is apt to rot before rooting occurs.

Once the cuttings are inserted into the soil, I trim the remaining leaves in half to cut down on transpiration loss. These leaves are still performing photosynthesis, even though there are no roots to draw moisture out of the soil. At this point, if I were propagating these cuttings for the nursery, I would move them into the propagation house where they would get bottom heat from a mat and moisture from a sophisticated misting system until roots develop.

 

  

5. Cover the wounds with hormone to boost the shoot's root-producing capability and to prevent rot.
 

  

6. Trim each set of leaves to minimize transpiration loss.

 

To mimic these conditions on a smaller scale, I stick small stakes into the corners of the six pack, then water the cuttings from the bottom. Finally, I tuck the tray into a plastic bag, which will create the humid conditions needed for rooting to take place. I then place the tray in a sheltered part of my garden that gets dappled sunlight and keep the cuttings moist until roots develop.

 

 
 

7. Place stakes at the corners of each tray to support the roof of your mini-greenhouse.

 

 8. Water the trays well.

 

 9. Place the tray of cuttings into a plastic bag. This mini-greenhouse will keep the cuttings moist until roots develop.

Check for root development

Some cuttings root faster than others. I've found that the best way to check for root development is with my eyes. After four to five weeks, I can check the bottom of each tray for small white roots that may be poking out of the drainage holes. If none are visible, another way to check for root development is by gently pulling on a cutting. If it shows some resistance, then it's a good bet that roots have developed. If it pulls out of the tray easily, I inspect the stem for very fine root hairs. If no roots are apparent, I place the cutting back into the tray, reseal the bag, and wait a few more weeks before checking again.

Depending on the species and the growing conditions, a healthy network of primary and secondary roots should develop after six weeks in the bag. My success rate varies from shrub to shrub, but generally I get roots on about 70 percent of my cuttings. once they've rooted, I pot up my tiny new shrubs into one-quart pots that I've filled with a mixture of 80 percent soil and 20 percent perlite, water them with a nutrient-rich seaweed- or kelp-based fertilizer and place them in a sunny spot in the garden. In the fall, I unpot them and transfer them to a sheltered nursery bed where they'll spend the winter. Come spring, I'll have a good supply of shrubs that I can move to a new, more permanent home.

 10. Monitor cuttings weekly for root development. These hydrangeas developed roots in three weeks.

 

 

 11. Pot up rooted cuttings into quart-size containers. Water them well, and transfer them to a sunny spot.
