Cleveland sage (Salvia clevelandii) is a stunning, drought-tolerant shrub native to California. Known for its silvery-green foliage and fragrant, lavender-blue flowers, it adds a unique and beautiful touch to any garden. If you’re looking to add this captivating plant to your landscape, starting Cleveland sage from seed is a rewarding and cost-effective option. This guide will walk you through the process, from selecting seeds to nurturing healthy seedlings.
Choosing the Right Seeds
The first step in your journey is selecting high-quality Cleveland sage seeds. You can find these at reputable nurseries or online seed retailers. Look for seeds that are fresh, plump, and free of any discoloration or damage.
Starting Seeds Indoors
For best results, start your Cleveland sage seeds indoors 6-8 weeks before the last frost in your area. This gives the seedlings a head start and allows them to establish strong roots before being transplanted outdoors.
Preparing the Seed Starting Mix
Use a seed starting mix specifically designed for starting seeds. These mixes are lightweight and well-draining, providing the perfect environment for germination. Fill seed trays or individual pots with the mix, moistening it thoroughly.
Sowing the Seeds
Gently press the Cleveland sage seeds into the seed starting mix, about ¼ inch deep. Don’t bury them too deep, as this can hinder germination. Space the seeds about 1-2 inches apart.
Providing the Ideal Environment
Cover the seed trays or pots with a clear plastic dome or wrap to create a humid environment. Place them in a bright location, but out of direct sunlight. The ideal temperature for germination is between 70-75 degrees Fahrenheit.
Germination and Care
With proper care, Cleveland sage seeds will typically germinate within 10-14 days. Once the seedlings emerge, remove the plastic dome or wrap to allow for air circulation. Continue to keep the soil moist but not soggy.
Thinning Seedlings
When the seedlings have a few sets of true leaves (not the first, seed leaves), thin them out, leaving the strongest seedlings about 2-3 inches apart. This gives each seedling adequate space to grow.
Hardening Off
Before transplanting your Cleveland sage seedlings outdoors, you need to gradually acclimate them to the outdoor environment. This process is called hardening off. Over a period of 7-10 days, gradually increase the amount of time the seedlings spend outdoors, starting with a few hours each day and increasing it until they can tolerate full sun and outdoor conditions.
Transplanting Outdoors
Once the threat of frost has passed and the soil has warmed up, you can transplant your Cleveland sage seedlings outdoors. Choose a location that receives full sun to partial shade. The soil should be well-draining and slightly acidic.
Preparing the Planting Site
Dig a hole for each seedling that is twice as wide and as deep as the root ball. Mix in some compost or other organic matter to improve soil fertility and drainage.
Transplanting the Seedlings
Carefully remove the seedlings from their pots, being sure to avoid disturbing the roots. Place each seedling in its hole, making sure the top of the root ball is level with the surrounding soil. Backfill the hole with soil, gently firming it around the roots.
Watering and Care
After transplanting, water your Cleveland sage seedlings deeply. Continue to water regularly, especially during the first few weeks after transplanting. Once established, Cleveland sage is drought-tolerant and only needs to be watered occasionally.
Enjoying Your Cleveland Sage
With proper care, your Cleveland sage seedlings will grow into beautiful, aromatic shrubs that will add a touch of California charm to your garden. They are relatively low-maintenance and will reward you with their stunning beauty and fragrance for many years to come.
Beyond the Basics: Tips for Success
Pruning for Shape and Growth
Cleveland sage can be pruned to maintain its desired shape and encourage bushier growth. Prune after flowering, removing any dead or crossing branches.
Pest and Disease Management
Cleveland sage is generally resistant to pests and diseases. However, it’s important to keep an eye out for any signs of problems. Aphids are a common pest, which can be controlled with insecticidal soap or a strong spray of water.
Winter Protection
In colder climates, Cleveland sage may need winter protection. Mulch around the base of the plant with a few inches of organic material to help insulate the roots.
A Lasting Legacy: Propagating Cleveland Sage
One of the joys of gardening is sharing the beauty of your plants with others. Cleveland sage can easily be propagated from cuttings. Take cuttings in the spring or summer, using sharp, clean shears. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a pot filled with a rooting mix, keeping the soil moist. Within a few weeks, new roots should form, and you’ll have new plants to share or add to your garden.
Embracing the Beauty of Your Garden
Growing Cleveland sage from seed is a rewarding journey that allows you to nurture a beautiful and fragrant plant from its very beginnings. With patience, care, and a touch of love, you’ll soon be enjoying the beauty and aroma of this unique and captivating shrub in your own garden.
