The large textured oval leaves are highly ornamental and remain dark green throughout the winter. The fruit is not ornamentally significant.
Yellow Jacobinia is a dense multi-stemmed evergreen shrub with an upright spreading habit of growth. Its strikingly bold and coarse texture can be very effective in a balanced landscape composition.
This is a relatively low maintenance shrub. Trim off the flower heads after they fade and die to encourage more blooms late into the season. It is a good choice for attracting bees and butterflies to your yard. It has no significant negative characteristics.
Yellow Jacobinia is recommended for the following landscape applications;
Planting & Growing
Yellow Jacobinia will grow to be about 8 feet tall at maturity, with a spread of 6 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 30 years.
This shrub does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by cuttings.
Yellow Jacobinia 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. 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.
