Plants reach approximately 24–30 inches and mature in approximately 115–125 days. Because this variety has a relatively long growing period, starting the seeds indoors is recommended for Canadian gardens.

King Size Lady Lavender Growing Information

Why Grow Lady Lavender Asters?

Silvery-lavender is a versatile flower colour that bridges cool blue and warm blush tones. It can be used in monochromatic purple arrangements or paired with contrasting apricot and yellow flowers.

The substantial rounded blooms give bouquets visual weight. They work as focal flowers in hand-tied arrangements and can also be repeated throughout larger floral designs.

Suggested companions include:

• White China asters
• Apricot asters and cosmos
• Blue and purple flowers
• Blush-pink blooms
• Silver-green foliage
• White snapdragons or stock

Pair Lady Lavender with King Size Apricot Aster for a balanced warm-and-cool planting. For an even lighter lavender flower, consider Hazaster Hagan Light Blue Aster.

How to Grow King Size Lady Lavender From Seed

Start seeds indoors approximately 6–8 weeks before the final expected spring frost. Because the plants need approximately 115–125 days to mature, an indoor start gives them more time to bloom before autumn cold arrives.

Fill clean seed trays with moist seed-starting mix. Sow seeds approximately ⅛ inch deep and cover lightly.

Maintain consistent moisture and moderate warmth. Germination normally occurs in approximately 10–14 days.

Move seedlings under strong grow lights immediately after emergence. Keep lights positioned according to the manufacturer’s recommendations so the plants remain compact.

Provide gentle airflow and avoid keeping the growing mix saturated. If roots fill the original cells before transplanting time, move seedlings into larger containers.

Additional growing information is available from the North Carolina Extension Gardener Plant Toolbox. Gardeners planning bouquet production can also review the University of Minnesota Extension cutting-garden guide.

Transplanting Lady Lavender Asters

Gradually harden seedlings off before transplanting. Increase their exposure to outdoor sunlight, wind, and temperature changes over approximately one week.

Plant outdoors after damaging frost is no longer expected. Select a location with full sun and fertile, well-draining soil.

Leave adequate space for airflow and avoid planting China asters in the same garden location every season. Crop rotation can help reduce recurring soil-related problems.

Watering and Fertilizing

Water regularly while the plants establish and throughout flower development. Aim for consistent soil moisture rather than alternating between very dry and saturated conditions.

Water near the base of the plant and avoid repeatedly soaking the foliage. Good airflow and early-day watering help the leaves dry more quickly.

Add compost before planting where needed. Use a balanced fertilizer according to its directions if plants require additional feeding.

Supporting the Plants

Although Lady Lavender is somewhat shorter than King Size Apricot, its large flowers can become heavy after rain. Support is helpful in windy or exposed locations.

Install horizontal flower netting over cutting rows or use individual stakes with soft ties. Place support early so stems can grow naturally through or alongside it.

Pinching is not required. Leaving the plants unpinched supports the substantial flower size and natural form of the King Size series.

Harvesting Lady Lavender Asters

Harvest when blooms have begun opening and display their mature silvery-lavender colour. Avoid cutting completely closed buds.

Use clean snips during a cool part of the day. Strip foliage that would remain underwater and place stems into clean water promptly.

Condition the stems in a cool location before arranging. The rounded flowers pair particularly well with delicate, airy fillers that prevent the bouquet from appearing overly dense.
