Oklahoma City, OK · Plant guide

Plants for Oklahoma City.

Oklahoma City buyers should begin with scale. Bald cypress can become a large tree, while beautyberry and Koreanspice viburnum occupy the shrub layer. Switchgrass adds upright texture; toad lily suits shade, and annual vinca should be treated as a warm-season annual.

Keep bald cypress for large sites

Allow roughly 30 feet of width and room for a tree that can reach 70 feet. A dwarf selection needs its own cultivar measurements.

Treat vinca as an annual

Wait for warm weather before planting annual vinca. Early cold can injure it, and disease-resistant cultivars are the safer purchase.

Bald cypress

Taxodium distichum

Bald cypress has a soft, feathery appearance but becomes a large tree. Use it where there is room for the mature canopy and roots, and check how its eventual size fits the rest of the garden.

Sun

Full sun.

Soil & water

Well drained through flood tolerant; drought tolerant once established.

Full-grown size

To 70 ft tall × 30 ft wide.

Through the year

Russet/copper-bronze fall color then needle drop.

Winter hardiness

USDA zone 4; large-space plant; dwarf selections need cultivar-specific facts.

Plant references

American beautyberry

Callicarpa americana

American beautyberry is grown for the purple fruit clustered along its stems. Give it enough width to keep its natural shape. It can take shade, though a sunnier position generally brings better fruiting.

Moist, well-drained.

Full-grown size

5-10 ft tall and broad.

Through the year

Lavender midsummer flowers; purple fruit in fall.

Switchgrass

Panicum virgatum

Switchgrass adds upright stems and airy flower heads that last into winter. Give it sun and space; rich soil or too much shade can make the stems flop, and some plants spread by seed or underground stems.

Sun

Full sun to part shade.

Soil & water

Most soils, wet or dry; drought tolerant once established.

Full-grown size

3-6 ft tall.

Through the year

Purplish panicles persist winter; yellow/orange fall then tan winter.

Winter hardiness

USDA 5-9; shade/rich soil can cause flopping; may spread by rhizome/seed.

Before you go to the nursery

Browse nurseries in Oklahoma City to find places to contact. Ask about the exact plants and varieties on your list before making a trip.

Bring a photo of the planting spot and its measurements. Note when it gets direct sun, how quickly the soil drains after watering, and whether you can water through a dry spell. Ask about the full-grown size of the exact variety on the label.

We have not confirmed local nursery listings for these plants yet. Use the botanical names above when you ask; common names can refer to more than one plant.
