Shrub Viburnum opulus 'Compactum' [Dwarf European Cranberrybush Viburnum] 'Compactum' is a dense, dwarf cultivar that produces an abundance of flowers and fruits and has excellent fall color. Widely tolerant of soils and microclimates, although found in more wet sites in wild stands. May be troubled by aphids. Prune on a 3-year cycle to maintain best form and fruiting. Flower cymes have an outer showy and sterile ring and an inner inconspicuous and fertile cluster which produces the berries.
Shrub Viburnum opulus 'Nanum' [Dwarf European Cranberrybush Viburnum] 'Nanum' is dense, dwarf cultivar that only reaches up to 1 1/2 - 2 feet tall. This variant rarely, if ever, produces flowers or fruits. May be troubled by aphids.
Shrub Viburnum plicatum f. plicatum [Japanese Snowball Viburnum] Relatively trouble-free plant. Unlike the Doublefile Viburnum (V. plicatum f. tomentosum), this species is sterile so it produces no fruit. One of the least drought tolerant of the Viburnums (may show leaf margin necrosis from drought in late summer). Prune on a 3-year cycle to maintain form, and never shear. Remove upright growing branches to accentuate horizontal character. Possibly the most elegant of flowering shrubs a choice specimen when placed near red.
Shrub Viburnum plicatum f. tomentosum [Doublefile Viburnum] The Doublefire Viburnum is fertile and more commonly used in the landscape than the sterile Japanese Snowball Viburnum (Viburnum plicatum f. plicatum). The white flowers are reminiscent of a lace doily with sterile showy flowers at edge surrounding the non-showy fertile flowers. Flower clusters accentuate the horizontal branching. Fruits are red that change to black if not eaten by birds, beginning in late summer.
Shrub Viburnum plicatum f. tomentosum 'Shasta' [Shasta Doublefile Viburnum] 'Shasta' is a prolific bloomer and handsome plant that has strong, horizontal branching. The Doublefire Viburnum is fertile and more commonly used in the landscape than the sterile Japanese Snowball Viburnum (Viburnum plicatum f. plicatum). The white flowers are reminiscent of a lace doily with sterile showy flowers at edge surrounding the non-showy fertile flowers. Flower clusters accentuate the horizontal branching. Fruits are red that change to black if not eaten by birds, beginning in…
Shrub Viburnum plicatum f. tomentosum 'Summer Snowflake' [Summer Snowflake Doublefile Viburnum] 'Summer Snowflake' is a tall, narrower form that is noted for its large, primary flower show in the spring, which is followed by continued, although sporadic, blooming into mid autumn.

Shrub Indiana Native Viburnum trilobum [American Cranberrybush Viburnum] Widely tolerant of soils and microclimates. May be troubled by aphids. Drought resistance is not good. Fruits are used in preserves.
Shrub Viburnum trilobum 'Compactum' [Dwarf American Cranberrybush Viburnum] 'Compactum' is a dense, dwarf cultivar that attains a height of 5-6 feet, about half that of the straight species. Excellent bloomer and fruiter. Widely tolerant of soils and microclimates. May be troubled by aphids. Drought resistance is not good. Fruits are used in preserves.
Shrub Weigela × 'Dark Horse' [Dark Horse Weigela] 'Dark Horse' is a compact, dwarf cultivar with deep purple leaves and abundant pink flowers. Spreading, dense, rounded shrub, with branches eventually arching to the ground. Extremely adaptable, but prefers good drainage and full sun. Some drought sensitivity. A 3-year pruning cycle improves form and prevents development of legginess. Flowers attract hummingbirds.
Shrub Weigela floribunda [Crimson Weigela] Less common, but very similar to Weigela florida (Old Fashioned Weigela), primarily differing in flowers (dark red-brown and not as showy) and less cold hardiness (USDA zone 6). Spreading, dense, rounded shrub, with branches eventually arching to the ground. Extremely adaptable, but prefers good drainage and full sun. Some drought sensitivity. A 3-year pruning cycle improves form and prevents development of legginess.
