Purple Dead Nettle VS Henbit

henbitBoth members of the mint family, purple deadnettle (Lamium purpureum) and henbit (Lamium amplexicaule) are often confused. Opposite leaves, square stems and purple flowers can make these weeds hard to differentiate. Learn how to tell the two apart with these helpful identification tips.

Henbit (Lamium amplexicaule)

What to look for: Pink to purple flowers; hairy leaves with rounded teeth

Life cycle: Winter annual; reproduces by seeds. Flowers in late winter/early spring; seeds mature from April to June. Will disappear under high-temperature stress.

Leaves: Hairy with rounded teeth; upper leaves clasp the stem

Flowers: Tubular with two lips; pink to purple in color

Roots: Fibrous

Look-alikes: Purple deadnettle, ground ivy, speedwells

Commonly found: Sites with thin, nutrient-rich soil

Purple deadnettle (Lamium purpureum)

What to look for: Purple-tinged leaves with pointed tips; purple-red flowers

Life cycle: Winter annual; reproduces by seeds. Germinates in fall, flowers in late winter/early spring.

Leaves: Opposite leaves with pointed tips have a purple tinge; grow on short or long petioles depending on where the leaf is located on the plant

Flowers: Purple-red; grow in clusters of three to six in the upper leaves

Look-alikes: Henbit, speedwells

Commonly found: Moist, shady sites with thin turf

Treatment recommendations for henbit and purple deadnettle: Both weeds germinate in the fall, reproducing by seed and flowers in the spring. Dense, lush turf is the best way to reduce the spread of these weeds. Apply a preemergence herbicide, such as, prior to germination in the fall. Properly mow, fertilize and water in spring and summer to minimize thin turf areas.

I googled mint and found a photo of your top photo. It was linked to a blog. I have no association with said blog, but here's what it said:
One of the true signs of spring is when the fields become misted with purple, like this one in Adams County. These purple pastures are the work of Purple Dead-nettle, Lamium purpureum, a non-native Eurasian weed in the mint family. It is quite ubiquitous, and I'm sure you've seen it. It is at its showiest when vast quantities cloak the fallow spring fields.
Like most mints, even weedy non-native ones, Purple Dead-nettle is quite striking upon close inspection

DALY: Use care when planting around septic drainfields  — Gwinnettdailypost.com
Shallow rooted annual and perennial herbaceous plants can be planted closer to the drain fields since they do not have invasive roots. Turfgrass can be grown over the drain field and is beneficial since it helps hold the soil in place.
