Eupatorium perfoliatum  (Boneset)

Eupatorium perfoliatum – Boneset

Collected in the Arboretum (and also) the Garden

Native, common but really puzzled me at first, initially because the flowers had not opened but in fact they do not have obvious petals.

Likes moist ground which may be why it has appeared in the garden this year (2017).

Oenothera biennis  (Common Evening primrose)

Oenothera biennis – Common Evening primrose

Garden arrival specimen so perhaps should be in Weeds although it is a native wild flower.

I can’t decide whether to keep it in the garden: it has flowers which attract insects but unfortunately that includes Japanese beetles. Does it keep them off other plants or merely attract them to the garden?

Veronica longifolia (Speedwell)

Veronica longifolia – Speedwell

Growing in the garden but purchased from a Wild Flower nursery. The name “speedwell” confuses because that is what I called V. persica in England, a low sprawling plant which is known here as Common field speedwell.

Campanula rapunculoides (Creeping bellflower)

Campanula rapunculoides – Creeping bellflower

Collected in Baie-D’Urfé

Another alien weed, although, mercifully these have not appeared in the garden – yet!

This plant is native to Europe and western Siberia and it has been introduced to North America, where it has become an extremely invasive weed. It chokes out other plants, and eliminating it is nearly impossible due to its multiple propagation mechanisms. It grows on grassy places, dry hills, meadows, in deciduous and pine forests, woods, fields and roadsides, along railway lines and hedgerows, preferably in partial shade, in dry to moist sites and on clay soils, relatively rich in nitrogen, at an altitude of 0–2,000 metres (0–6,562ft) above sea level. It also occurs in cultivated fields as a weed.

Dianthus armeria (Deptford pink)

Dianthus armeria – Deptford pink

A nice weed.

Non-native from Europe. It appears to flourish in a clay-loam or gravelly soil that is somewhat compacted and heavy. Dry to mesic conditions. Included in weeds because it arrived in the “nursery” area of the garden.

Blue, or Common, Vervain

Verbena hastata – Blue or common vervain

Collected in the Arboretum – 16 July 2017

Growing in Morgan Arboretum next to the muddy pond on the main/orange trail

Tall with multiple flower spikes. NA native.
