The present invention relates to methods of propagating plants.
More particularly, the present invention relates to methods for propagating plants of the genus Heliconia and propagation products produced from such methods. Further, the present invention can extend to methods for propagating plants that fall outside of the Heliconia genus and producing plant products from the same.
The genus Heliconia includes various species of flowering plants, including those referred to as “lobster claws.” These plants are tropical, being indigenous to Central and South America. The plants are popular in the United States, though propagation occurs in tropical regions in which the plant thrives. Propagation and shipping to the United States is thus required for sales in this country, but relevant regulations promulgated by the U.S. Department of Agriculture limit the importation of, inter alia, soil and other media that can carry invasive pests. This limits how many plants, including Heliconia, can be propagated and imported into this country.
The typical method that is currently practiced is to grow Heliconia plants in ground beds in a tropical area. As the plants start to send up new “suckers”, these suckers are dug up and cut from the mother plant to ship to the final customer. The suckers then need to be rooted at the customer level before it can be transplanted to its final pot to be grown out to maturity. From there, the transplanted Heliconia needs to grow an individual stalk and flower to then start initiation of side shoots and produce a full, attractive, commercially viable product.
There are substantial shortcomings with the existing methods, particularly the significant amount of time needed to grow the transplanted Heliconia from sucker, to individual stalk and flower, to full plant with side shoots. Because of this time, and unfavorable growth climates in the United States, particularly the northern states, it can be difficult to provide adequate supplies of Heliconia. Accordingly, the need exists in the art for improved methods of propagating Heliconia.
Accordingly, provided herein are methods of propagating a plant including the steps of planting at least a portion of a plant in growth medium, growing the portion of the plant until a shoot forms, pruning the portion of the plant, growing the portion of the plant and shoot until a plurality of shoots have formed, dividing the pruned plant from the shoots, and replanting one or more of the shoots, each shoot being replanted in separate growth media. In some aspects, the plant is a Heliconia. In some aspects the plant is planted in a pot. In certain aspects, the pot has a diameter of between about 4 inches and about 6 inches. In further aspects, the pot has a diameter of about 4 inches.
In aspects, the portion of the plant and shoot are grown until at least four shoots are formed.
In aspects, the step of pruning the portion of the plant includes removing a growth tip of the portion of the plant.
Also provided herein are methods of preparing a commercial Heliconia product including the steps of planting at least a portion of a Heliconia plant in a growing medium, growing the portion of the plant until a shoot forms, pruning the portion of the plant, growing the portion of the plant and shoot until a plurality of shoots have formed, removing the plurality of shoots from the growing medium as a clump, removing media from roots of the clump, and wrapping the roots of the clump in a substrate. In some aspects, the plant is a Heliconia. In some aspects the plant is planted in a pot. In certain aspects, the pot has a diameter of between about 4 inches and about 6 inches. In further aspects, the pot has a diameter of about 4 inches.
In aspects, the portion of the plant and shoot are grown until at least four shoots are formed.
In aspects, the step of pruning the portion of the plant includes removing a growth tip of the portion of the plant.
In aspects, the substrate is coconut fiber. In further aspects, the coconut fibers are moistened with a liquid. In particular aspects, the liquid is water.
In some aspects, one or more nutrients are added to the growing medium. In some further aspects, the growing medium is soil.
In some aspects, the method of producing a commercial Heliconia product further includes the step of replanting the clump in growing medium. In further aspects, the growing medium is soil.
Also provided herein are products formed by the above methods.
Also provided herein are horticultural products including a plurality of rooted shoots or bibs of Heliconia and a substrate surrounding the roots of the shoots or bibs. In some aspects, the substrate is coconut fiber. In further aspects, the coconut fiber is moistened. In some aspects, the roots and substrate are received within a container. In some further aspects, the substrate maintains a pH of from about 5.5 to about 6.5.

With reference to
In accordance with the method described herein, when additional shoot(s) appear in the pot with the original bib (20), the original bib is pruned (30). In a preferred aspect, the original bib is pruned to eliminate only the growing tip of this original bib. This allows it to retain at least one leaf that helps in the food production for the growth of suckers, but renders the original bib non-viable for future production. The original bib and the nascent shoot(s) are then left in the pot until a desired number of shoots is reached (40). A non-limiting example of a pot with multiple Heliconia shoots is shown in
In aspects (not shown in
With continuing reference to
In aspects, the shoots/clump are grown with exposure to one or more nutrient additives suitable for maintaining the health of the clump, such as a fertilizer. In particular, with regard to Heliconia, suitable nutrient additives can include magnesium supplements, calcium supplements, nitrogen supplements, phosphorous supplements, potassium supplements, and iron supplements. In other aspects, the liquid provides a slightly acidic environment for the roots of the clump, for example, and without limitation, a pH of between about 5.5 and about 6.5, all subranges ranges therebetween inclusive. This pH range matches that which should be present in the growth medium during growth of the shoots in the pot, prior to removal, washing, and wrapping/encasing.
The wrapped or encased Heliconia roots can then be further wrapped or encased in, for example and without limitation, a container such as those made of plastic or other material suitable for shipment of living plant material. A non-limiting example of Heliconia clumps with roots enclosed in a container is shown in
Accordingly, also provided herein is a horticultural product including a plurality of rooted shoots or bibs of a plant such as, for example and without limitation, Heliconia. The roots of the rooted shoots/bibs are surrounded by, embedded in, or received within a substrate as described above. In some aspects, the substrate is coconut fiber. In a preferred aspect, the substrate is moistened coconut fiber. In additional aspects, the roots of the plurality of shoots and the substrate are further received within a container, as described above.
The methods described herein produce a commercial product that includes a Heliconia with multiple bibs having a root system wrapped or encased in a substrate. This commercial product is superior to those produced from prior methods of Heliconia propagation in that the commercial product will already include multiple bibs. This allows for a more efficient finishing and quicker production of flowers, allowing the sale of Heliconia in geographies where prior methods, which required substantial times to produce commercially-viable product, made availability impossible. Whereas prior methods could provide a flowering Heliconia in 17 weeks, methods as described herein allow for production of a commercially viable Heliconia product in as little as 12 weeks.
