Darmera peltata
Darmera peltata
(dar-MARE-ah pell-TAY-tuh)
Syn. Peltiphyllum peltatum; Saxafraga peltata
Family: Saxifragaceae
Common name: umbrella plant; Indian rhubarb
Zone: 5 – 7
Height: 3 – 5 ft (0.9 – 1.5 m)
Spread: 3 – 5 ft (0.9 – 1.5 m)
Aspect: sun; partial shade; full shade
Soil: humus-rich; moist; average; clay
Water: regular; moderate
Description: Herbaceous perennial with thick rhizomes. Small pink and white flowers in terminal, rounded corymbs appear atop thick stems in early spring before the foliage. Large, 18-inch (45 cm) wide, medium green, rounded, lobed leaves with serrated edge follow the blooms, forming a large mound which lasts throughout the season with regular watering. Stunning foliage colour in autumn.
Special Notes: Native to mountain streambanks and woodland areas in SW Oregon and northern region of California. Prefers medium to wet soil conditions in part to full shade but tolerates average and clay soils with regular watering. Will also tolerate full sun locations if plant is kept consistently moist.
The tall leaf stalk, or petiole, is attached in the centre underside of the large leaf which creates a shallow cup-shape. This allows the upward facing leaves to collect a small pool of rain water. Various insects often avail themselves of a drink.
This plant species spreads exponentially by rhizamous roots so give it adequate space. It is ideal for moist, boggy areas, as well as assist in stabilizing sensitive stream and pond margins. No serious insect or disease problems. Propagation by division.
In our Zone 7a garden: This plant has pride of place in its own bed beside our pond. It is in a full sun location and is watered regularly so we can attest to its stunning autumnal display.
We have not experienced any problems with the exception its spread will exceed 5 feet (1.5 m) which necessitates reducing its size every 5 to 7 years.

Cyclamen coum
Cyclamen coum
(SIK-la-men KO-um)
Family: Primulaceae
Common name: Persian violet, eastern sowbread
Zone: 5 – 9
Height: 3 – 6 in (7.5 – 15 cm)
Spread: 6 in (15 cm)
Aspect: sun; partial sun; shade
Soil: fertile; humus-rich; well-draining
Water: drought tolerant once established
Description: Tuberous perennial with round or heart-shaped dark green leaves which may have some silver or grey markings. Flower colour ranges from white through shades of pink with darker staining at the base of the petals. This is a spring ephermeral…flowering from December through March, depending on region, and going dormant through the summer.
Special Notes: Native to the Mediterranean, this delightful winter-blooming perennial does well as an understory specimen in rhododendron, maple, birch, Douglas fir and western red cedar plantings.
Self-seeding, this plant naturalizes nicely with the help of ants who are attracted to the sugary coating on the seeds. Tiny seedlings start to appear in late fall. Once the plants are established, they are drought tolerant.
Generally, disease- and pest-resistant; deer resistant.
In our Zone 7a garden: I have a slowly increasing patch of Cyclamen coum flowers underneath the Acer campestre, (European hedge maple), which are purely delightful when they come into flower in the middle of winter for us.
This bed in the garden landscape is a difficult one due to the maple roots sucking up all of the nutrients…leaving little for the other plants residing there. Because of this, I am always impressed by the plants who manage to survive such harsh treatment.
Awards: Named by the Royal Horticultural Society as one of the top 200 plants of the last 200 years.
Caution: Toxic to dogs and cats if ingested.

Crocosmia ‘Lucifer’
Crocosmia ‘Lucifer’
(kro-KOZ-mee-ah)
Family: Iridaceae
Common name: monbretia
Zone: 6 – 9
Height: 3 – 4 ft (90 – 120 cm)
Spread: 18 – 24 in (45 – 60 cm)
Aspect: full sun; partial shade
Soil: average; well-draining
Water: moderate
Description: An herbaceous perennial with a fairly upright, clumping habit. Medium green leaves, looking very much like long blades of grass, drape wonderfully in a vase-like form. Arching stems of eye-catching flame red, funnel-shaped flowers appear in mid-summer through autumn.
Special Notes: A native to South Africa, this is a good cut flower for floral arrangements. Attracts bees, butterflies and especially hummingbirds. Plant grows from corms. Seeds do not always come true. Seed is used largely in the production of new varieties. Established clumps should be divided every 3 – 4 years in spring or autumn. Few pests or disease.
In our Zone 7a garden: We love this plant for the hummingbirds and butterflies it attracts to our garden. However, John does tend to curse it every so many years because he has left its necessary maintenance division too long. And when he finally gets around to it, digging it up out of the ground for dividing has turned into a real grunt job. He has to bring out the no-nonsense tools – drill steel and axe.
Honestly, when you have to start roping the mass of blade-like leaves to keep them from smothering the smaller plants surrounding ‘Lucifer’ you have to know you should have divided the Crocosmia last year…or the year before. But to give John his due credit, he is very meticulous in maintaining his horticultural display to perfection. There just are not enough hours in the day to get to everything.

Cotinus ‘Grace’
Cotinus ‘Grace’
(koe-TY-nus)
Family: Anacardiaceae
Common name: smoke bush; smoke tree; smokewood
Zone: 4 – 8
Height: 10 – 15 ft (3 – 4.5m)
Spread: 10 – 15 ft (3 – 4.5m)
Aspect: full sun; partial shade
Soil: moderately fertile; well-draining
Water: moderate
Description: Deciduous shrub with a pleasing, multi-branched, natural-forming shape. Boasts lovely round leaves that emerge light red in spring, darkening to a reddish-purple in summer before turning a brilliant orange-red in autumn. Large, open panicles of frothy pink flowers appear in early summer.
Special Notes: A cross between Cotinus coggygria ‘Velvet Cloak’ (a seedling discovered in a nursery in the US) and Cotinus obovulatus (native to SE United States). Pleasing, natural growth form requires little pruning and then only to keep paths clear or make room for its neighbour. Deer resistant. Tends to be susceptible to verticillium wilt and powdery mildew. Allow airflow to minimize contracting these diseases. Propagation is difficult.
In our Zone 7a garden: John planted ‘Grace’ on the south side of our pond to create some shade for the goldfish. However, we soon discovered the shrub’s height was impacting on getting past it on our way to the greenhouse or toolshed. This prompted John to coppice…cut back…the shrub to just above the soil level. Doing this annually meant the shrub’s new growth remained better behaved and did not overly impact on the path.
Full disclosure, however, because coppicing ‘Grace’ every year meant our shrub did not produce any frothy pink flowers. It was a sacrifice we endured though as we still were able to enjoy the lovely changes in its foliage as the days progressed into autumn.
Unfortunately, we were forced to remove ‘Grace’ from the garden when we had to renovate our fish pond in 2021. And that is the whole thing with a garden…change happens on a regular basis.

Corydalis solida
Corydalis solida
(kor-ID-ah-liss SOL-ih-dah)
Family: Papaveraceae
Common name: fumewort; bird-in-a-bush
Zone: 4 – 8
Height: 6 – 10 in (15 – 25 cm)
Spread: 12 – 18 in (30 – 45 cm)
Aspect: full sun; partial shade
Soil: moderate; well-draining
Water: moderate
Description: A spring ephemeral perennial with a low mounding habit. Tuberous roots will slowly spread out to produce a soft carpet over time. Grey-green leaves are deeply divided and fern-like. Tubular-shaped flowers with an upswept spur sit atop a slender stalk. Floral colour can be blue-mauve to purple, or reddish and white. Whatever the colour, it will be consistent on one plant. Blooms mid-March through spring. Being an ephemeral, the plant completely disappears come summer.
Special Notes: Native to northern and central Europe and Asia where this plant grows in meadows and woodlands. British gardeners have been cultivating it in their gardens since late in the 16th century. Very easy care; relatively pest and disease free. Moderately drought tolerant, but does benefit from some watering. Deer and rabbit resistant. Propagation by division in early spring or by fresh seed in late spring. Seed needs a stratification period in dappled shade to germinate. Not deadheading the spent flowers right away is a guarantee you will have one or two new seedlings pop up the following year. (Try not to disturb the soil around your fumeworts too much or you may lessen your chances of new seedlings.)
In our Zone 7a garden: This plant was a new addition to my front garden in Spring 2015. A gift from a friend, it was broken into three clumps and planted under the Acer campestre (European field maple). Fast forward two or three years and it has become a lovely early spring presence in the bed outside the front room window. There is nothing like signs of growth and early flowers after the tough months of winter.
