Growing Sarracenia

Sarracenia planted in pots growing in a galvanized steel water tray. The tray is topped up with water every morning during the growing season. It is never allowed to dry out. The plants are at table height which allows easy access and viewing.

Sarracenia leucophylla
Three different clones of Sarracenia leucophylla in a 46 cm (18 in) pot. The pot is not sitting in water since free water attracts squirrels and raccoons and overflowing water can damage the decking. Please see Display Sarracenia on your deck for information about the construction of the pot.

A Sarracenia cage to keep out squirrels and raccoons. Squirrels and raccoons will trash your plants if given the chance.

Sarracenia cold greenhouse
Growing Sarracenia in a hoop house in USDA zone 7. The hoop house allows the plants to get a one month head start in the spring on plants grown outside and extends the growing season farther into the fall. It can be quite hot inside during the summer. Snow on the roof can be a problem.

Sarracenia leucohylla
During the winter, snow is good for the plants as it protects them from cold.

Sarracenia are among the easiest carnivorous plants to grow. If you have a location outside with full sun and have or can easily get water low in minerals there is no excuse not to grow these spectacular plants. If you do not have a full sun location outside there are certain Sarracenia species that can be grown indoors under lights.

The genus Sarracenia consists of 15 species and subspecies found naturally only in North America. All but one of those taxa are restricted to the southeast USA with the epicenter of the genus on the coast of the Gulf of Mexico. The taxa restricted to the Gulf coast are considered warm temperate. That is they expect seasonal changes but do not handle freezing weather and short growing seasons very well. The taxa found naturally inland or along the Atlantic coast, Virginia south, are more cold temperate. They do not require freezing temperatures but do naturally get them in the wild. They also are more tolerant of shorter growing seasons. Sarracenia purpura subsp. purpura, which is found in the northeastern USA and southern Canada, is very cold temperate but does well in areas with moderate winters. There are thousands of Sarracenia hybrids each with its own growing preferences.

Some species such as Sarracenia psittacina, S. rosea, and most S. minor types are best adapted to long growing seasons and mild winters as occur along the Gulf Coast between Texas and the Florida panhandle. S. psittacina in particular is freeze sensitive. The Sarracenia rosea and S. minor are all fully hardy to USDA zone 8. The other Sarracenia species are fully hardy to USDA zone 7 although some Sarracenia leucophylla clones may need protection. It is the early and late freezes that can be deadly. The plants in pots will survive a weeks frozen solid if they are fully dormant and do not freeze-dry.

In USDA zone 6 it is best to concentrate on plants from the Carolinas and highlands such as Sarracenia flava, S. oreophila, S. jonesii, S. purpurea, and hybrids containing S. purpura subsp. purpura. The plants can be grown in artificial bogs in the ground and heavily mulched during the winter (please see Growing Carnivores in Canada). If there is a surprise early or late freeze with the plants unmulched, put row cover over them.

In USDA zone 5 and colder your only option for plants outdoors year round is Sarracenia purpura subsp. purpura. Other Sarracenia species in pots can be overwintered in cold greenhouses as well as cold frames, unheated garages, unheated sun porches, and even basements. It is important the winter storage location is cool to cold since if it is too warm the plants can start growing prematurely and have trouble with the transition to outdoors in the spring.

Sarracenia appreciate long growing seasons and warm to hot summer temperatures. In areas with short growing seasons or cool summers it is helpful to have plants in a greenhouse or hoop house. In areas with very hot temperatures and low humidity you might have trouble with the pitchers burning. Some afternoon shade can help.

Sarracenia psittacina and S. rosea are the species recommended for growing indoors under lights year round. These species along with Sarracenia leucophylla make great heated greenhouse plants. All other Sarracenia can be grown in greenhouses in areas with inadequate summer heat. It is difficult to grow the tall species under lights unless you use mirrors or other reflective material to get light to sides of the tall leaves.

The long tube Sarracenia varieties that are mulched or stored in a protected location during the winter should be given a haircut in the fall. Plants outdoors unprotected can get their yearly haircut anytime while dormant although it is usually best to wait until they start to send up flower buds since the old leaves afford some protection. This haircut may be short or long depending on the species or hybrid. The reason for cutting back the previous years leaves is to remove overwintering places and eggs of mealybugs, aphids, scale and other nasties and to allow air circulation to discourage mold. (If you have trouble with mold on the plants, dust with sulfur.) The problem with cutting back green leaves is they help the plants get started in the spring. This is especially important for species like those in the Sarracenia rubra complex that bloom before the spring leaves come out. At minimum remove the upper part of the pitchers where emerging flowers and leaves could snag and anything brown.

Sarracenia purpurea, S. rosea, and S. psittacina should only have their pitchers removed when they turn brown. Individual pitchers of these plants can last up to two years.

Although Sarracenia are fen plants where water moves through the soil, they can be grown in the ground in artificial bogs made from molded plastic pond shells, plastic sheeting, or pond liner. Although the plants do not mind total immersion for short periods of time, it is best to keep the water level 7 to 12 cm (3 to 5 in) below the soil surface and to add water to the bog on the side opposite to the drain.

The best way to grow Sarracenia is in pots sitting in water. For mature specimen plants, pots 16 to 20 cm (6 to 8 in) wide work best. The pots should always be sitting in about 4 to 6 cm of water. Sarracenia should never be allowed to dry out. The pots can sit in standard plastic plant trays, metal trays, or trays constructed with rot resistant wood and black plastic or pond liner. It is best to have an automatic watering system so watering your plants does not become a chore and you do not have to worry about being away from home.

The default soil for Sarracenia is standard 1:1 peat:sand CP mix. For plants outdoors where they get plenty of water to flush the soil, perlite can be substituted for sand. Some clones of Sarracenia purpurea subsp. purpurea and S. minor may do better in live sphagnum while S. psittacina likes pure peat and short pots.

Unless you are growing plants commercially, there is little benefit to soil fertilization of mature plants. If the plants are getting full sun and they appear to need a boost, 1/2 tsp per gallon of a low urea, high nitrogen water soluble fertilizer in the pitchers and/or sprayed on the pitchers could help. Over-fertilization can result in burned pitchers, failure to produce normal pitchers, or even killing the plant.
