Smooth hydrangea (Hydrangea arborescens)

Kemper Code: K520
Common Name: smooth hydrangea
Zone: 3 to 9
Plant Type: Deciduous shrub
Family: Hydrangeaceae
Missouri Native: Yes
Native Range: Eastern United States
Height: 3 to 5 feet
Spread: 3 to 5 feet
Bloom Time: June - September Bloom Data
Bloom Color: White
Sun: Part shade
Water: Medium
Maintenance: Low
Best grown in average, medium moisture, well-drained soil in part shade. Tolerates full sun in the northern part of its range, but needs constant moisture. Intolerant of drought, with foliage tending to become significantly less attractive in dryish conditions. If left alone, this Hydrangea can become somewhat weedy in appearance and can spread rapidly by root suckers to form colonies. Blooms on new wood, and in cold winter climates, it is perhaps best grown as an herbaceous perennial (e.g., cut back to 1-2' from the ground in late winter).

• Height: 3-5 feet
• Flower size: 1 inch long

Blue-eyed grass (Sisyrinchium angustifolium)

Stout blue-eyed grass is probably the most common of six species of blue-eyed grass found in Connecticut. The photo below right shows some of the distinguishing features for stout blue-eyed grass. Incidentally, don't rely on the name narrowleaf blue-eyed grass; this species, in fact, has the widest leaves of any blue-eyed grass in the state.
• Family: Iris (Iridaceae)
• Habitat: meadows, shores
• Height: 4-20 inches
• Flower size: 1/2 inch across
• Flower color: blue
• Flowering time: May to July
• Origin: native
Blue star willow (Amsonia tabernaemontana)
Black-eyed Susan (Rudbeckia hirta)
Bird's foot violet (Viola pedata)

This species seems to be everyone's favorite violet. The large, flat-faced flowers with prominent orange stamens and the very finely cut leaves distinguish birdfoot violet. Coast violet and early blue violet have cut leaves, but their flowers look fairly different.
• Family: Violet (Violaceae)
• Habitat: dry, sandy fields; sunny rocky areas
• Height: 4-10 inches
• Flower size: 1 to 1-1/2 inches
• Flower color: purple; upper petals sometimes much darker than the lower petals
• Flowering time: April to June
• Origin: native

• Family: Honeysuckle (Caprifoliaceae)
• Habitat: woods and open woods
• Height: 3 to 12 feet
• Flower size: 1/8 inch flowers in heads 3 inches across
