Butia sp.

Butia sp. - Arecaceae

Our Butia sp. is just one of the 12 species of Butia native from Brazil to Argentina. We are not quite sure which species we have, but I suspect it may be a B. yatay. The bluish green, gracefully arching pinnate leaves reach up to 5 feet (1.5 m) long. Petioles are armed with spines up to 3 inches (7.5 cm) long. Our specimens at 10 years old from seed have attained a height of 10 feet (3 m). Butias are among the cold hardiest palms in the world. Most species can be grown in the landscape in USDA zones 8-11.

Blooming: At 10 years old from seed our palms have never bloomed.

Culture: Butia sp. needs full sun to partial shade with a well drained soil mix. In the greenhouse, we use a soil mix consisting of 1 part peat moss to 2 parts loam to 2 parts sand. The plants are well watered and allowed to dry before watering again. We fertilize them monthly with a balanced fertilizer. Even though they are fairly fast growing, they don't require a lot of repotting. We have repotted ours every 3 years since the seedlings germinated. During the winter months, the plants are placed in the cool rooms in the greenhouse, where the nighttime temperatures never fall below 48°F (9°C). Water is somewhat restricted during this period and fertilizers are withheld until new growth starts in the spring.

Propagation: Butia sp. is easily grown from seed.

Butia was featured as Plant of the Week May 11-17, 2007.
