Growing Information
|
How to plant:
Propagate by
seed,
cuttings
- Start from seeds indoors 6 to 8 weeks before the last spring frost. Do not cover, as the seeds need light to germinate. Easily grown from cuttings, which can be taken at any time of the year, but best in late summer for winter indoor growth, and late winter/early spring from indoor plants for outdoor summer growth. Use young, non-woody stem cuttings, which can be rooted either in potting mix or in water. Despite general variety uniformity, coleus seeds do not produce identical plants. If uniform plant type/color is desired, start plants from cuttings.
Germination temperature: 70 F to 75 F
Days to emergence: 7 to 14
Maintenance and care:
Pinch off flowers as soon as they appear to keep plant compact and bushy. Regularly pinch back tips to keep bushy. Keep moist but not wet. Expect Coleus to be one of the first plants killed back by fall frosts.

Variations in leaf types include: ruffled edges, entire (smooth) edges, and toothed edges. Cultivars also varying in height. �Carefree� Strain: compact plants that branch without pinching. Lobed leaves come in a variety of color combinations. Good container plant. �Sabre� Mix: elongated leaves are tapered like sabres, hence the name. Dwarf. Good in shade and part shade. �Rainbow� Strain: very colorful leaves in a wide variety of color combinations. Plants are very uniform. �Wizard� Series: heart-shaped leaves in a variety of green, bronze and red/pink combinations. Doesn�t require pinching, and branches from the base. Many plants in the series have yellow tones. Dwarf (10� tall).
