An attractive large shrub with narrow green leaves and small yellow floral tips, surrounded by large, bright scarlet bracts; fairly drought tolerant, but better with some irrigation; protect from frost; adds a truly exotic dimension to the garden
St. Louis Red Garden Poinsettia features showy clusters of yellow flowers with red overtones and scarlet bracts at the ends of the branches from late fall to mid winter. It has attractive green evergreen foliage. The narrow leaves are highly ornamental and remain green throughout the winter.
St. Louis Red Garden Poinsettia is a multi-stemmed evergreen shrub with an upright spreading habit of growth. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.
This is a relatively low maintenance shrub, and should only be pruned after flowering to avoid removing any of the current season's flowers. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
St. Louis Red Garden Poinsettia is recommended for the following landscape applications;
- Mass Planting
- General Garden Use
- Container Planting
Planting & Growing
St. Louis Red Garden Poinsettia will grow to be about 8 feet tall at maturity, with a spread of 10 feet. It has a low canopy with a typical clearance of 1 foot from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 15 years.
This shrub should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is not particular as to soil pH, but grows best in rich soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets. 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.
St. Louis Red Garden Poinsettia makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
