With light lime green flowers that amazingly coordinate perfectly alongside any other colored flower, Lime Green flowering tobacco is a delightful garden plant! This hybrid tender perennial that is most widely regarded as an annual bedding plant will tolerate light winter frosts and will behave as a tidy perennial if trimmed back in autumn after flowering wanes.
The oblong lance-like leaves are an attractive emerald green. In summer's warmth, the rosette of leaves sends up a lightly branched stem that bears many tubular flowers with five lobes, each colored a bright but light lime green. Flowers are often closed in full sun but open in late afternoon and into dusk, releasing fragrance to help guide pollinating moths to the nectar. Seeds later form and will drop to sprout nearby when growing conditions are favorable.
Grow 'Lime Green' in full sun to partial shade situations in a moist, fertile and well-draining soil. It is delightful in annual beds, perennial mixed borders as well as containers. In regions where it will perennialize (for only a couple seasons), use it in the cottage garden.
It is most versatile if grown as an annual to unite and contrast flowers that are purple, blue or white; granted it looks good around anything! In tropical regions sow seeds outside of the hot, humid rainy season.

Sow indoors from February to April. A warm kitchen windowsill is all you need for starting these seeds.
Sow thinly on the surface of a tray of pre-watered compost. Place in a warm, light position. A temperature of +15-20C is ideal.
Keep the compost moist. The tray can be covered with clingfilm to preserve humidity, but remove when seedlings appear, usually in 14-28 days.
Transplant them 5cm apart to other trays when large enough to handle. Always hold by a leaf, never by the stem.
Grow on in cooler, but not cold conditions. Gradually accustom young plants to outside conditions (avoid frosts), before planting out, May-June, 30cm apart, into well-drained soil, when frosts are over.
