Cranberry Bush Flowers

Excellent fall foliage color which may be yellow, red, orange or burgundy is just one of the many attributes of this large and attractive native shrub. Showy, snow-white, flat-topped flowers are 3"-4 1/2" in diameter that bloom in mid to late May. Beginning in September, bright red fruits serve as food for birds and wildlife. Grows 8'-12' high with an equal spread. Prefers good, well-drained, moist soil and partial shade to full sun.


Flowers: It produces flat-top clusters of showy white flowers in June. The clusters are 2 to 3 inches across, with an outer ring of larger, sterile flowers. The flowers are hermaphrodite (having both male and female organs) and are therefore self-fertile, meaning that an individual plant’s flowers can pollinate one another, so there is no need for a second type (or even a second individual plant) to provide pollen and produce fruit. The flowers are pollinated by both wind and insects. Answer: No. Viburnums tend to be self-fruitful. That is, an individual plant’s flowers can pollinate each other, and there is no need for a second type (or even a second individual plant) to provide pollen. And, if you are planting native plants, every one is genetically different from another. In terms of cross-pollination, planting two individual native plants would be the same as planting two hybrids/cultivars. Most of the highbush cranberry viburnums sold in the landscape industry are selections from the wild, or hybrid cultivars that have been developed. These types are valued for their larger fruits, brighter-colored fruits, bolder fall color, dwarf form, etc.

Answer: Yes. Highbush cranberry can be pruned annually. It grows quickly, and in the absence of pruning becomes a rather massive, mounded shrub (they’ve been known to reach 15′ x 15′). If you want to keep it from getting larger than desired, essentially maintaining its present size (assuming it has not yet reached full size), prune each year just after flowering. For pruning guidelines, see the following bulletin and check the information about “heading back” branches (Bulletin #2169).Relationships: There are about 150-175 species of Viburnum in temperate regions of the Northern Hemisphere with a few species found in mountainous regions of South America, Southeast Asia & Africa (in the Atlas Mountains). There are about 20 native to North America. Many species are popular garden and landscape plants. Several hybrids and cultivated varieties. have been developed. They are grown for their flower display and/or showy fruit, Some have fragrant flowers; some with attractive or unusual evergreen leaves or fall color. (Source: nativeplantspnw.com)
