How to Propagate
Direct sowing
Seeds need light to germinate â do not bury them deeply. For an early start, begin seeds indoors 8-10 weeks before the last frost date. Self-seeds freely if flower stems are left to dry.
- 1 Sow seeds directly in the garden after the last spring frost
- 2 Barely cover seeds as they require light to germinate
- 3 Keep soil moist during germination
- 4 Thin seedlings to 30-45 cm spacing
- 5 Refrigerate seeds for 2 weeks before sowing to improve germination rate

Common Problems
Fusarium Wilt
Fusarium wilt is a serious fungal disease caused by the soil-borne fungus Fusarium oxysporum. The fungus invades roots and blocks the water-conducting vessels (xylem) of the plant, causing progressive wilting and eventual death. Host-specific forms of the pathogen exist that attack different plant species.
Rust
Rust is a common fungal disease caused by fungi in the order Pucciniales that affects a wide variety of plants. The disease gets its name from the characteristic orange, yellow, or reddish-brown pustules that appear on leaves, resembling metal rust. This obligate fungal parasite requires living plants to survive and can cause significant economic losses in agricultural crops.
Downy Mildew
Downy mildew is a fungal-like disease caused by oomycetes (water molds) that thrives in cool, wet conditions. It affects a wide range of plants, causing yellowing leaves with fuzzy white-gray growth underneath, leading to defoliation and reduced yields if left untreated.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Meaning & Symbolism
Symbol of good luck and prosperity in many cultures, particularly in Irish tradition. Often used in wedding arrangements for good fortune.
