Planting & Growing
Red Threads Alternanthera will grow to be about 8 inches tall at maturity, with a spread of 12 inches. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.
This plant does best in full sun to partial shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone over the growing season to conserve soil moisture. This is a selected variety of a species not originally from North America. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
Red Threads Alternanthera is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a canvas of foliage against which the thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
