History

In 1768 when Admiral Louis de Bougainville began his long journey to the Pacific Ocean and discovered the vine that now bears his name, it was a botanical highlight of the voyage. Through the ensuing years, this Brazilian beauty has assumed its rightful place as one of the most popular, spectacular and beautiful tropical plants. The modern day hybrids of Bougainvillea spectabilis (B. Brasiliensis) and B. glabra are among the most beautiful of flowering vines.

Growing Bougainvilleas

These tropical members of the Nyctaginaceae (Four-O'Clock) family, are very vigorous, evergreen, woody vines with spines. Although normally climbers, they can be trained to stay bushy as pot plants, hanging baskets, or as standard 3 or 4 feet high. They will bloom beautifully on branches on 18"-20" long. Keep all long shoots cut back to 18"-20" for best bloom. The vibrant color of this vine comes not from the small white tubular flowers, but from the 3 large paper-like bracts that surround each flower.

Culture

They grow readily from cuttings 4"-6" long, and in 4-6 weeks will develop good root systems when given bottom heat and mist. When well rooted in perlite/peat moss mix, they can be potted in small containers in a soilless mix with added pine bark to give more drainage. Care should be exercised in transplanting since the fine roots often do not knit the soil together in a firm root ball. When repotting annually, slice off the outer 1"-2" of the root ball, and repot in the same size container. Bougainvillea need very bright light (2,500 fc) and do well under high shade or in full sun. These vines typically lose some leaves for a short time during the winter, but when light conditions are low, leaf loss may occur at any time. Under high light conditions, the colorful bracts will adorn the plant almost constantly and will persist for weeks.

Fertilization

These vines are heavy feeders and respond best to almost constant feeding with 1/2 strength water soluble fertilizer, e.g., Peter's 20-20-20, Excel 21-5-20, Miracle Grow or Rapid Grow. With high light and constant feeding, the plants will bloom at least 11 months of the year. Straight hibiscus food has also been a very successful fertilizer.

Watering

These plants flower best under stress. Keep the plant slightly on the dry side, and allow the plant to become root bound.

Insects

Bougainvilleas are almost totally insect free. The occasional "cabbage looper" or aphid can be treated with the appropriate pesticide.

Best varieties

The blooms as we know them are not true flowers, but are 3 large papery bracts that encircle small, white, tubular inconspicuous flowers much like the poinsettia. Some of the best bougainvilleas to look for in your local garden centers are: golden yellow 'California Gold', and its gold and green leaved variegated from 'Vickie', the dark pink flowers of 'Juanita Hatten', and its new mutation with green leaves spatter painted with gold. 'Barbara Karst' Bright red to bluish crimson in shade, blooms very young, likes heat. 'Sundown' Apricot color, vigorous, good bloomer, heavy feeder. 'Jamaica White' white, veined with green, bloom young, vigorous. 'Texas Dawn' smaller pink flowers, in huge clusters, vigorous, keep cut back. 'Double Pink' clear pink, vigorous, keep trimmed back, spent flowers must be cut off since double flowering types will not shed flowers in the typical fashion. 'Surprise' large, clear pink-white bi-color flowers, easy bloomer.

Growing in containers

Plants do best in large (5-10 gallon) clay containers if grown outdoors (clay containers tend to stay drier, thus stressing the plants) or in large handing baskets. The 10" basket is the commercial standard, but plants will do much better in 12" hanging baskets. Place the containers in full sun, or in a place where they will receive at least 1/2 day of full sun. If your bougainvillea is not blooming, it probably is not receiving enough sun or fertilizer. These plants thrive in the tropics in areas of low rainfall and intense sun and heat. Any well drained potting soil mix is suitable for growing Bougainvillea. Try to use a mix consisting of 4 parts of well rotted pine bark, 3 parts peat moss and 2 parts of coarse perlite. To about 5 gallons of this mix add 1/2 cup of Osmocote and 2 tablespoons of 19-5-9 slow release lawn fertilizer.
