| This is a bad swap time except for very mild winter areas. Were they potted up 2 months ago so they will have had time to form a root mass? If they have a root mass, they probably will be safe if that root mass is kept intact as they are placed in soil. Generally rhizomes are planted (with the tops of the rhizomes exposed) 6 weeks before the first frosts dates to allow root growth before frost. Some people in cold winter zones report success placing pots (or the bare rhizomes) in a garage or basement and planting in spring after freezes are over. Top photo shows this lavender plicata, color and pattern, well for trading purposes. I would probably post the trade offer in May. Many people with noids (no identification name) do not have a photo and you have to rely on their color description. After bloom, the rhizomes may be dug and cleaned, roots & foliage trimmed, dried, and mailed. They can be cushioned with crushed dry newspaper. |
