Mountain Laurel


Evergreen shrub 3 – 9 feet tall. All parts are deathly poisonous to several animals, like horses, humans, deer, cattle and sheep… but NOT to dogs or cats! First noted in America in 1624. The Latin name is after Pehr Kalm, who sent samples of it to Linnaeus in the 1700s. Blueberry family. Native to the eastern U.S. (Thanks to A.F. Donna for sending me out after this one!)

Swamp Rose

A lovely rose growing in moist soil on the lakeshore. Extremely fragrant. Native to the eastern U.S. While I took this, Lucy scouted out a big turtle.

High Bush Cranberry



I originally identified this as maple-leaved viburnum, but with further research, it’s looking like this is High Bush Cranberry — based on the size (and shape) of the flowers relative to the leaves. We’ll know for sure in the fall — cranberries will have edible red fruit and the viburnum will have purple black fruit. This is growing everywhere at Centennial. A low shrub. Native to North America, and not a true cranberry, but a species of viburnum.

Common Blackberry


There are a lot of these blooming at Centennial. I was trying to identify them as roses, but actually– they’re blackberries. The canes arch and bend downward to send new roots into the ground. No fragrance. Fruits are seedy and sweet. The nectar, pollen and fruits attract many kinds of bees, flies, beetles, caterpillars, birds and mammals. Also the brambles form shelter for many ground-nesting birds and other small creatures… so the value of this plant to its local ecosystem is high.

Bristly Locust

Kudos to A.F. Donna for spotting this at Wilson Mountain. There is an area just full of these low shrubs all hung with pink blossoms. Pea family. Native to the southeastern U.S…. so these have somehow escaped and migrated northward.

Arrowwood Viburnum

The name is because Native Americans used the straight basal shoots as shafts for mounting arrowheads. In mid to late summer will have blue-black berries. Foliage turns yellow to red to purple in the fall. Native shrub.

Chokeberry

Not sure if this is Red or Purple Chokeberry. They are cultivated as ornamental plants! The name chokeberry refers to the astringency of the fruits which must be cooked — they’re used for wine, jam, syrup, tea, etc. (Birds do not mind the astringency and eat them freely.) Rose family. Native. (Thanks to Alert Flowerophile John for loaning me his Newcomb Guide, which helped me identify this plant.)

Chokeberry (Pyrus)

Common Barberry

This is growing in the woods behind our house. Like so many things this spring, I’ve never noticed it blooming before, but it’s quite lovely. Barberry family. Origin: Europe. Compare to earlier post on Japanese Barberry — this one is evidently not a bad marauding invader. Just an invader.

Tartarian Honeysuckle

This looks a lot like the Morrow Honeysuckle, but it’s pink, found on Fisher Street in Needham. It’s an exotic invasive bush honeysuckle. Evidently all native honeysuckle species are vines. This variety was introduced to North America as an ornamental in 1752. (I wonder what the story is there.)
