Coleus blumei Hybrid is one of the most commonly grown Coleus. Here at the greenhouse we use this Coleus for all kinds of experiments for Introductory Botany. It is mainly used for photosynthesis experiments and hormone experiments. Coleus blumei Hybrids have the widest array of leaf colors of any of the other coleus species. Whether grown in containers or in the landscape they are very showy.
Blooming Time: Although they will bloom at any time of the year, they bloom heaviest in the fall. The small blue flowers with the colored foliage are very showy.
Culture: Coleus blumei hybrids are easy to culture. They need a rich, well-drained soil mix and will grow in full sun to full shade. In the greenhouse, we use a soil mix consisting of 2 parts peat moss, to 2 parts loam, to 2 parts sand or perlite. Since we use these plants for class experiments they are kept moist for optimum growth. The plants are fertilized weekly with a balanced fertilizer diluted to ½ the strength recommended on the label. Plants are grown the year round. Seasonal modifications are not necessary, as growth is vigorous under many conditions.
Propagation: Coleus blumei hybrid can be grown from seed or from cuttings. We have grown these plants from cuttings for 30-40 years now from plants started in the early 1960's.
Coleus blumei Hybrids was featured as Plant of the Week February 27-March 4, 2004.
