Gaura Lindheimeri is a perennial flowering plant native to the southern reaches of North America. It has a woody base, and produces 12-20" flower stalks adorned with white to pink blossoms.

Start Gaura seeds indoors 8-10 weeks before the last expected frost, or outdoors in early spring. Some gardeners recommend giving these seeds a 60 day cold treatment before planting, which can also be performed by sowing the seeds in autumn.

Grow Gaura in an area of full sun in average soil that is well-drained.

• If manually performing a cold treatment, mix the seeds with sand inside a plastic bag. Place this bag in the fridge for 60 days before planting. These seeds can also be sown outdoors in the fall, allowing winter to prepare the seeds for spring germination.
• If starting indoors, use trays or small pots filled with a seed starter mix.
• If starting directly outdoors, first prepare a seedbed by weeding and breaking up the soil. Amend with organic matter if soil is poor.
• Surface sow 2-3 seeds per plant, and barely cover with sand or other media.
• Keep seeds moist until germination, and maintain a temperature of 65-75F degrees. Using a heat mat can be helpful. Under proper conditions, these seeds should germinate in 2-4 weeks.
• Once indoors seedlings have their first few sets of true leaves, they can be transplanted outdoors at the end of frost season. If ultimately growing in a container, a large pot will be needed to accommodate this plant's taproot.
• 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.
• Gaura should be watered regularly until established, after which it becomes drought-tolerant and only needs to be watered during dry spells. Gaura does not perform well in soggy soil.
• Fertilization is largely unnecessary, as Gaura tolerates poor conditions.
• Lightly shearing back the plant after the first flush of flowers die out can encourage further blooming.
