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.

Wild Carrot

The name Queen Anne’s Lace seems to be applied to at least two weeds, but this one is Daucus carota – Wild Carrot

It is also known as Wild carrot and the young plants certainly resemble carrot tops. As the flowers mature they produce the characteristic “bird’s nest” as the individual florets curve in. The stems and leaves are prickly/hairy and the inflorescence or umbel is flat-topped.

Not to be confused with Wild chervil (Cow parsley) Anthriscus sylvestris whose umbels are more dome shaped, the flowers a little more delicate and only the lower stems hairy.
