100+ Spike Lavender seeds, Lavandula latifolia, 1/2 gram
Lavendula latifolia
Spike is also called Portuguese lavender.
Allow six weeks for germination. The plants establish rapidly, producing silver green foliage with bright, vibrant, blue-purple flowers that attract beneficial insects. The plants themselves will reach a mature height of 12 to 18 inches tall.
Lavender likes full sun and a well draining, slightly alkaline soil. Lavender is hardy to Zone 5. It will not tolerate poor drainage, full shade or high humidity. Space plants at least 3'-4' apart when planting out.
Use well-draining potting mix when planting and do not bury seeds, but merely press the seed on the surface. Keep moist but not soggy. Seeds can take 4-6 weeks to germinate, but may germinate faster if scarified by sandpaper. Seedlings that are blue-green are healthy and happy. Seedlings that are yellowish may be getting too much water, the soil may not be draining fast enough and/or the soil may be too cool.
Mature lavender is usually drought tolerant. A favorite of many bee species.
