Heliopsis is a resilient flowering perennial native to North America. It has a long bloom season, and readily self-sows. Heliopsis makes for a great cut flower, but it also serves well in beds and borders.

Heliopsis seeds should be started indoors 4-6 weeks before the end of frost season, or directly outdoors after all frost danger has passed.

Plant Heliopsis in an area of full sun in average soil that is well-drained. It can tolerate partial shade, and also doesn't mind poor soil conditions.

• To start indoors, use trays or small pots filled with a seed starter mix. Sow 3-4 seeds per plant at a depth of 1/8 inch.
• If sowing directly outdoors, first prepare a seedbed by breaking up soil and removing weeds.
• Keep seeds lightly moist until germination, maintaining a temperature of 65-70F degrees. Under proper conditions, these seeds should germinate in 2-3 weeks.
• Once indoor seedlings have their first few sets of true leaves, they can be transplanted outdoors after all frost danger has passed.
• Before transplanting seedlings into the garden, it's essential to "harden them off". This involves acclimating young plants to outdoor conditions by placing them in a sheltered outdoor area for about a week. Initially, shield them from strong winds and direct sunlight. If there's a risk of frost overnight, either cover the plants or bring them indoors, then return them outside in the morning. This hardening off method helps strengthen the plant's cell structure, minimizing transplant shock and sun damage.

• Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
• Mulches play a vital role in preserving soil moisture and ensuring consistent soil temperatures. When it comes to annuals, using organic mulch made from shredded leaves not only enhances the appearance of the bed but also enriches the soil as it decomposes over time. Remember to keep mulch away from the plant stems to avoid potential rot issues.
• Heliopsis should be watered fairly consistently, waiting for the soil to dry out in between waterings. Heliopsis is fairly drought-tolerant once established.
• Heliopsis plants can become leggy if soil is too rich, so fertilization is not advised.
• Pinch plants in the spring to encourage branching growth, and regularly deadhead spent blooms during the growing season to encourage further flowering.
