Plant Species Information

Observation

I love going back to sites and seeing how my plant installs are doing. We know it’s not always good news, like the case of my yew screen. I always feel responsible for the plants, as if they were my dependents.

The line of Portuguese laurels (Prunus lusitanica) shown below is doing well. We didn’t lose a single specimen, which is fantastic. We’re finding that Portuguese laurels do much better in heat than cedars (Thuja occidentalis). Also, note that the heights are mostly uniform because the light levels are fairly even.

English laurels

Now let’s walk away from the Portuguese laurels, around the corner to the back, and see a line of English laurels (Prunus laurocerasus).

What do you notice here? The plants are doing fine; they’re clearly receiving water from nearby sprinklers. However, you will notice how slanted they are. The left side is doing extremely well, while the right side looks like the youngest sibling. I planted them all at the same time. The big difference is the nearby Japanese snowbell tree (Styrax japonicus). It clearly shades out the laurels on the right and competes with them for resources.

That’s basic plant biology. Plants need access to light so they can produce food in their leaves through photosynthesis. Less light means less food. The effect of shading is nicely visible here. Not as obvious is plant competition where the roots compete for resources.

Changes

You can leave it as is, or, you can prune the laurel hedge to even it out. Another option is pruning the trees around the hedge, mainly the Japanese snowbell nearby. If the unit owners are worried about privacy, you can just thin out the trees by removing selected branches. Raising the crown by eliminating the lowest branches is more obvious. Both pruning procedures would allow more light in.

Always check with the owners before making significant changes.

Pampas Friday

I have a weakness for ornamental grasses. They look awesome when the wind sets them in motion, they flower in the fall, and they look fantastic when frost covers them. We cut them back in early spring and then leave them on autopilot for the rest of the season.

If the clumps get too big, you can dig them up and divide them in late spring.

This past Friday, one of my co-workers kept referring to Pampas grass (Cortaderia selloana) all day when, I was hundred percent sure, we were looking at Chinese silver grass (Miscanthus sinensis). I quietly ignored the directions to cut them back because it’s too early. Miscanthus holds its structure nicely and looks great all winter. I say let it be and come back in early spring.

I found other work nearby.

Gardens illustrated

I still had Pampas grass on my mind after work, when I picked up the November copy of Gardens Illustrated. (It comes from the UK so it’s slightly behind). And there it was on pages 70-75, saying that Pampas grasses were back in style. I’m not sure why people stopped loving them but fans of dried flowers are partly responsible for its comeback. They look good to me. I just don’t see them that much.

Early spring is the only time you have to touch them. Cutback the old stems and remove one third of the foliage. Just remember that the foliage can cut your fingers, so use gloves. That’s it, you’re done for another year. Low-maintenance and great look!

If you like Pampas grasses but hate waiting until September to see the flowers, there is a ‘Patagonia’ variety available, according to the article in Gardens Illustrated. It flowers in June. Check with your local nursery.

Conclusion

Ornamental grasses look fantastic in the landscape because, unlike shrubs, they move with the wind. They flower in the fall and, if you don’t cut them back too early, they look beautiful covered with frost.

Cut them back in early spring.

If you like the look of Pampas grass, get some for your garden. It’s now back in style.

Plant ID fight club

Do you struggle with botanical names? I know I do. Remembering botanical names is always a fight. As soon as I learn a few new ones, I see a plant I know and it takes me several minutes to recall Liatris spicata. So, this blog post is a kind of trick. While it introduces you to an evergreen fern, Asplenium scolopendrium, it also builds my memory and yours. I hope.

Asplenium scolopendrium stands out in our gardens because its fronds are solid and evergreen. I love the way it looks.

When my residential clients asked me about plants for their shady sidewalk bed, I mentioned the Hart’s tongue fern and they bought some. Of course, after learning the botanical name Asplenium scolopendrium I picked up the plastic pot and the tag said Phyllitis scolopendrium. I shouldn’t have panicked because my Google search would soon reveal that it was just a synonym, not a different species.

Asplenium has a connection to “spleen” and scolopendrium refers to “centipedes”, presumably because the sori (spores) on the frond undersides are arranged in rows, thus resembling centipedes.

Now, I’m hoping this information will jog my memory when I walk by a specimen of Asplenium scolopendrium. If it doesn’t, I will have to Google my own blog post. But, I feel like this is a good start. Spleen and centipedes.

Caring for Asplenium scolopendrium

I could list everything here but you might as well read the tag I photographed. One key is good drainage because this fern can suffer from root rot. Otherwise, it’s disease and pest free.

Install fun

Good clients listen and learn from you. When I suggested a few of my favourite shade plants, they bought them without hesitation and at hefty retail prices.

We put Black Mondo grass (Ophiopogon planiscapus) in front and two fern species in the back: Asplenium scolopendrium and the native sword fern (Polystichum munitum). They all looked fine a year later when I visited the home recently; there is adequate shade but I do wonder about road salts spilling over.

To summarize

Remembering botanical names isn’t easy but it’s important. I struggled to remember Asplenium scolopendrium but typing it out in this blog post 35 times might help. You can also think Asplenium (spleen) and scolopendrium (centipedes). That might hep jog your memory.

Another important step in remembering botanical names is actually planting the specimens in the ground. I keep plant tags whenever possible; and sometimes my wife finds them laundered and shredded at the bottom of our washing machine.

Now, when I go back to my client’s place to do bed clean-up, I should be able to blurt out Asplenium scolopendrium. I might even remember Phyllitis.

A tattoo

It all started with a tattoo I saw on a young summer helper’s arm. You don’t often see flowers on young men’s arms so I asked a few questions, like any other plant geek. The flower in question was the Flannel flower (Actinotus helianthi). The genus Actinotus means “furnished with rays”.

Why put it on your arm? What’s so special about it? I did some research on Google to find out because the dude is no longer employed with us and I don’t recall what exactly made him choose the Flannel flower. I just remember that his father was from Australia and when they visited the country, the dude must have noticed the flowers around Sydney.

The Flannel flower is a symbol of purity used in festivals and religious ceremonies.

It’s also adaptable and enduring which is why it’s able to survive in the bushland around Sydney.

The daisy-shaped flower is also beautiful and strong which is why it’s Australia’s national symbol for the promotion of mental health awareness. The dude’s tattoo was OK but I didn’t see the beauty until I saw pictures on Pinterest. Now I understand.

Botanical notes

The Flannel flower is actually very interesting because its stems, flowers and leaves are all grey in colour; and they’re all covered in soft downy hairs. Thus the flannel name.

We know that hairs are an adaptation for avoiding water loss. That’s why the flower can survive in the bushland; and why it’s a good plant for a rock garden.

The flowers appear in spring; you can grow them from seed or cuttings and plant them in well-drained, sunny locations.

Plant lust

I think every plant on Earth is interesting and the Flannel flower definitely fits. I’m glad I asked my co-worker about his tattoo because it inspired this blog post. If you ever find yourself in Sydney, you will be ready to explore thanks to my blog post.

Almost spring

The older I get, the more I hate winter and cold weather. So, to cheer myself up I’ve put together a little late winter photo essay. Most of the plants are well-known in our landscapes. Only one was new to me, the fourth picture down.

Winter Aconite (Eranthis hyemalis) emerges before crocuses with bright yellow flowers, then come green, lobed leaves.

Enjoy!

Under 1 minute

I love this! It took me less than a minute to reply to a message on WhatsApp asking what the tree species name was. Take a look. Do you know it?

The answer is Sourwood (Oxydendrum arboreum). Now, I know this site really well and it also happens to be the only site in our portfolio planted with Sourwood. That’s why it’s easy to remember.

Of course, the fall colors are also stunning.

And while it looks good to answer the question quickly, it’s not a contest with prizes. Plant identification skills are important because to properly care for our landscape plants, we first have to know what they are. It’s our starting point.

Imagine how stunned I was when a fourth level apprentice in landscape horticulture told me he didn’t care about the plants I named nearby. It didn’t do anything for him. What? Horticulture is about plants. I would love it if someone would show me all of the plant species on site. Sadly, I’m the go-to guy and, as it turns out, it’s not really appreciated. It pains to write these lines.

First encounter

I remember my first encounter with Sourwood as if it was yesterday. It actually happened in 2014, when I worked for the City of Coquitlam parks department. My city gardener boss pulled up to a small city park and the only tree in the parking lot was a huge Sourwood specimen.

As was her habit, my boss quizzed me immediately, but I drew a blank. Now I have the city gardener boss-failure-Sourwood association burned into my brain. And that also frees me to learn other plant names; and there are many more to learn about. Recall that gardening starts with plants!

To have success in horticulture and gardening, you will have to learn about plants. That’s obvious. If you’re interested in one or both, it’s probably because you love plants. So, keep going and feel free to share your discoveries in the comments section.

My goal is to ace every plant ID inquiry on WhatsApp in under a minute!
