Also known as the Swan River Daisy, it is considered a hardy perennial in USDA zones 9 to 11 and is grown as a cheerful annual in zones 2 through 8. Its easy-going nature and extended blooming season, from summer through fall, make it a favored choice for flower gardens, rock gardens, and containers.

Plant seeds indoors in seed trays with a layer of seed-starting mix, four to six weeks prior to the average last frost date. Ensure the soil medium remains moist until germination, which should be within 10 to 18 days. To maximize the plant's flowering cycle, sow your seeds in stages, spacing each sowing two to four weeks apart.

Grow in full sun and well drained soils.

• Sow seeds indoors in trays 3 - 4 seeds per cell four to six weeks before the average last frost date
• Do not cover seed, but press firmly onto soil.
• Keep soil moist until germination.
• You can make the most of the plant’s bloom cycle by sowing seeds in phases spaced two to four weeks apart.
• As seedlings appear, ensure they receive ample light by placing them on a sunny windowsill or under fluorescent plant lights, positioned 3-4 inches above, for 16 hours a day followed by 8 hours of darkness at night. Adjust the lights higher as the plants grow. Avoid using incandescent bulbs as they generate excessive heat. Remember, most plants need a period of darkness to grow, so it's important not to leave the lights for the full 24 hours in a day.
• Before planting outdoors in your garden or containers, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

• Maintaining control over weeds is crucial throughout the growing season. Weeds compete with your plants for water, space, and nutrients. Manage them with frequent cultivation or by applying mulch to inhibit the germination of their seeds.
• Typically requires a midsummer pruning to encourage bushy new growth and to revive the plant, priming it for a fall blooms.
• In the summer's peak heat, following the initial bloom, cut the plant down to half its size.
• Deadheading is beneficial throughout the blooming period. Removing spent flowers or snipping blooms at their peak for indoor display encourages the new flowers.
• Swan River daisies are usually cultivated as annuals, if you wish to overwinter the plants, you'll need to uproot them and bring them indoors. To achieve this, prune away the dead growth, carefully unearth the root ball, and transfer it to a pot that provides sufficient drainage and is filled with porous soil. Once repotted, move the plant indoors and position it near a window that receives plenty of sunlight. Continue growing your daisy indoors, but don't expect it to bloom in the winter. Come spring, relocate it outdoors after all threat of frost has passed. Brachycome in zones 9 to 11 may be pruned back to the ground to overwinter in your garden.
• Brachycome require abundant sunlight to flourish with prolific blooms. If grown in shaded areas and flower production is limited, relocating them to a sunnier spot may be necessary.
