Crossandra is a lovely perennial that produces abundant blooms throughout its growing season. It doesn't tolerate cold weather, but can be overwintered indoors in harsher climates.

Crossandra seeds should be started indoors in the late winter or early spring. If growing as a houseplant, it can be started any time of year.

Crossandra performs best in an area of partial shade with loamy, slightly acidic soil that drains well.

• Sow these seeds into trays or small pots filled with a seed starter mix.
• Spread seeds over the soil surface, and then lightly cover with soil.
• Keep seeds moist and at a temperature of 78-82 degrees. Under proper conditions, germination should occur in 1-2 weeks.
• Once all frost danger has passed and seedlings have a few sets of true leaves, thin to the strongest seedling and transplant outdoors spaced 1-2 feet apart, or into individual pots.
• 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.
• Keep soil consistently moist (but not wet), not allowing it to dry out. During winter, reduce watering to once per week.
• Apply a slow-release fertilizer to outdoor plants once per month, and lightly apply a liquid fertilizer every two weeks to indoor plants.
• Deadhead spent blooms as necessary to tidy up plants and encourage further blooming.
