New and Different: Garden Changes

I think it’s time to get away from book reviewing and rule quibbling. Whatever else might be happening, there’s always the garden.

It’s fall in the garden. Rain and imminent plant dormancy eliminates the need to water (except for a few pots). The gardener is energized. Plans are made and a few are carried out.

Hosta "Stained Glass"
Hosta “Stained Glass”

Nurseries put plants on deep discount at this time of year, rather than carry them through the winter. So I bought a rather nice hosta (called “Stained Glass”) for half price. Its leaves are a translucent yellow with blue-green margins. It complements the other hostas (dark green with white margins and medium green with yellow margins; you can see them in the featured image above). I also got a late summer/early fall blooming gentian (Gentiana septemfida). If it settles in and blooms well, I’ll have glowing blue trumpet-shaped flowers at both ends of the season, since I already have spring-blooming Gentiana acaulis.

Flowers like these, only in fall.

A few days ago, I weeded the pond. Yes, ponds need weeding at times. I’ve had an oxygenating water plant (Elodea canadensis) in the pond for years, but for some reason there was way too much of it at summer’s end. There’s also duckweed (Lemna minor), a small, lime green surface floater, which can be sort of pretty, but not if it’s wall-to-wall. So I hoicked out masses of both and added them to the compost pile.

I have two compost piles. By mid-October I have to make room for the leaves that are about to descend. Usually I stack the old pile of not quite finished stuff on top of the current one containing fresh material. By the following spring it’s all pretty much rotted down enough to be distributed among the planted areas. But this year’s old compost (mostly last fall’s leaves) looked so finished that I decided to spread it around immediately, at least in spots where that could be done without damaging plants still in good shape.

The Boulevard Project progressed well this summer. The chicory and Queen Anne’s Lace looked great together and several clumps of California poppies bloomed and produced seeds, and therefore more plants. A couple of them are an unusual creamy pink colour; the rest are the usual bright orange. I happened to obtain seeds of two native plants — consumption plant (Lomatium nudicaule) and seaside rein orchid (Habenaria greenei) — and scattered them around before a week of rainy weather. If they take hold, I think I’ll dig out some of the chicory and QAL. My original idea was to emulate a country roadside, but I think it’s better to encourage plants that belong here, rather than hearty imports.

The other day, I pulled out the last of the soaker hoses, rolled it up, and stashed it in the shed. (Wrestling hoses can be an exceedingly trying process; don’t do it if you’re feeling crabby or are in a rush.) Were the soakers effective as watering devices? For perennials, I would say yes. But not so much for shrubs.

The Chinese Witch Hazel (to the right of the bench in the featured image at the top of the post) showed drought stress from early summer. Its leaf edges began to turn orange-brown as early as June and it once again has no plans to bloom. It really isn’t a suitable choice for this climate, unless planted in a naturally damp area or given deluxe irrigation. I haven’t been able to bring myself to remove (i.e. kill) and replace it, though.

A much better choice of shrub is Ocean Spray (Holodiscus discolor), which I recently planted in one of the mixed beds. It’s a native plant of the region, a graceful, early summer blooming shrub that’s definitely at home here. It should outperform the witch hazel without any extra help once established (but unlike the witch hazel, it doesn’t bloom in January with an enchanting perfume — but then, neither does my witch hazel).

Speaking of failures, I’m declaring 2020 the Last Chance Year for Meconopsis (blue poppies) in this garden. The two plants I purchased in March bloomed well in May, but dwindled and died in August. I thought crown rot in winter was the main hazard, but it turns out that powdery mildew is another. It strikes in hot, dry weather, despite diligent watering. Although these prima donnas didn’t even last the summer, they did produce seeds before they turned up their toes.

Gone but not forgotten. Not yet.

That gives me a chance for one last shot. In January, I will deposit those seeds on damp, sterile, seed-starting mix and keep them at indoor temperature for a week or so. Then I’ll cover the pot and set it in a safe spot outside for exposure to frost and cold temperatures. Seeds should begin sprouting by March. I’ve had fairly good luck with this process in the past, even to the point of a dozen or so plants in bloom (a glorious sight!). After that, the trick is getting them through the following winter. Or even, it seems now, the following summer. One last try.

Sunflower and chickadee

This year I finally got around to growing sunflowers. I had seven or eight plants. They were okay, I guess, but not nearly as impressive as some I’ve seen. In rich soil and full sun, with adequate water, a sunflower grows branches that develop buds, resulting in something like a tree. In soil that’s poor, sandy, and often dry, they stick to one skinny (although tall) stem with a single flower. (Guess which kind I had.) They did produce enough seeds to attract chickadees, who diligently pecked them out and ate them.

Some plants are totally reliable without any extra effort at all, like these hardy cyclamen. They’ve increased well over the years and now form nice carpets of pink flowers that mingle with other plants and the falling leaves. Their own beautifully patterned leaves are starting to emerge and will last into next spring.

Winter Scents and Flowers

Summer in the garden is now a fading memory, but gardeners may be planning for next year, considering new plants for their gardens. In this fortunate part of the world (Zone 8 or 9 to those familiar with the USDA climate zones), winter flowers are starting, with more anticipated. For gardeners lucky enough to live in similar climates, here is a short list of plants that bloom between November and March, most of them with delightful perfumes.

IMG_3065Winter jasmine (Jasminum nudiflorum) is in its first flush of bloom in my garden. I love the way it hangs down the trellis, displaying its bright yellow funnel-shaped flowers. The buds are yellow with red tints, and should keep opening at least until February, unless we get brutal weather. Sadly, despite its name, which suggests fragrance, winter jasmine has no scent at all. But Anna’s hummingbirds, who are year-round residents here, visit the flowers regularly. The plant is easy to grow and to propagate, as stems that touch the ground form roots at the point of contact. In fact, I have to keep an eye on it to prevent unwanted rooting.

violets, Viola odorata

The common sweet violet (Viola odorata) is one of those near-weeds that moves in and makes itself at home. I’ve had to thin it out in a few spots to keep it from overrunning other plants. But on relatively warm winter days, its perfume wafts around and reminds me why I’m happy to have this plant in the garden. It pretty much takes care of itself. Deer nibble it sometimes, but it’s tough and regrows. It’s even moved into the lawn, which is fine with me.

Chinese witch hazel, Hamamelis species

Chinese witch hazel (Hamamelis mollis and hybrids) is described thus in one gardening manual: “… one of the most uniquely beautiful of winter-flowering shrubs when its vigorous upright branches are set with its spidery, bright yellow, richly fragrant flowers.” I couldn’t resist that, so resolved to plant one of these marvelous shrubs in my garden. The book says witch hazels “…thrive in deep, well-drained soil, preferably sandy loam enriched with plenty of leafmold or compost. They prefer light woodland conditions, but do well in full sun, especially if given ample moisture during the growing season.”*

Chines witch hazel foliageMy witch hazel is situated in conditions similar to those, so it should thrive, meaning bloom, but mine hardly ever does — only once or twice in 25 years. I suspect the problem is insufficient moisture in summer. Our increasingly warm, dry summers don’t bode well for future success, and in fact my plant looked less than happy at the end of last summer. But its shape is elegant even without blooms, and it sometimes has good fall colour. I know of several plants in the vicinity that bloom regularly, exuding their wonderful fragrance on January days, so I live in hope.

Spurge laurel, Daphne laureola

Spurge laurel (Daphne laureola) really is a weed shrub, an undesirable alien that has invaded woodlands in this region. I wouldn’t recommend it to anyone who gardens near woods that are as yet without it (sort of like ivy, which has overrun most natural parks around here). However, it was already present in this garden when I arrived, so I’ve kept a few plants. Needless to say, it grows well in dry, rooty soil, and its leathery black-green foliage looks good in dark corners at the edge of the garden where not much else will grow. The black berries don’t seem to appeal to birds, so the seeds tend to sprout close to the parent plant, which makes the seedlings easy to find and pull up. Its best feature, as far as I’m concerned, is the haunting perfume of the little green flowers. I catch whiffs of it on February nights, when I’m checking the max/min thermometer on the back porch. The scent induces a nameless nostalgia, to the point that I worked a mention of it into one of my novels.

Sweet box (Sarcococca species) is a shrub I don’t have here as yet, but having read that it “tolerates dry shade,” I’m thinking about where I might plant one. It’s strongly perfumed, as I know from encounters with it on walks in my neighbourhood. It’s a broad-leaved evergreen, 3-4 feet (1 metre) tall, with flowers that look like those of witch hazel, except they’re white. One of the species (S. hookeriana) is said to “spread easily by underground stems,” which raises a red flag for me. I already have too many shrubs with that tendency. So perhaps S. confusa or S. ruscifolia are the ones to look for.

winter honeysuckle, Lonicera fragrantissima

Winter-blooming honeysuckle (Lonicera fragrantissima) is a shrubby plant (unlike the climbing honeysuckles). It can get quite tall (15 feet or 5 metres) and almost as wide, but can be pruned as hard as needed to keep it within bounds. It’s a semi-evergreen, which means it sheds weirdly yellow-grey leaves practically year round. Some of the previous year’s branches wither in summer and look seriously ugly, screaming to be pruned. On the plus side, it blooms in late winter and early spring. The flowers are white and sort of semi-transparent, so they don’t look like much, but they produce an intensely sweet lemon scent, especially on still, damp evenings. For that I’m willing to forgive its ugly duckling qualities.
