Tropaeolum Germination Information

Tropaeolum Seed Germination How to Sow Tropaeolum:

  • Best sown outdoors after all danger of frost is past
  • Seeds can be started indoors at 65° with germination occurring in 7-12 days
  • Indoors and out, completely cover the seeds as they need darkness to germinate
  • Alternatively, sow seeds outdoors after all danger of frost has past
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Tropaeolum:
Transplanting: Transplant when there are at least two sets of true leaves, being very careful with the roots as they resent being disturbed

Spacing:  Space 8-12 inches apart in full sun to light shade

Soil: Site in a slightly acid or slightly alkaline, light, sandy, dry, poor, well-drained soil. Plants flower best in poor soils; rich soils promote foliage growth at the expense of flowers. No need to fertilize

Temperature: It grows best in dry climates with cool summer nights

Appearance and Use:

VA vigorous annual for use as a ground cover in beds, as edging, and for summer screening. It also works well trailing over the sides of containers and walls. Plants can be of two forms: trailing and climbing to 8 feet or compact and bushy to 12 inches. The 2- 21/2 inch flowers are funnel-shaped with a spur in the back. Where happy, they will flower from late spring through to frost. Petal arrangement is either single or double in colors of yellow, orange, red, salmon, and apricot. The pale green, 2-7 inch diameter, round leaves are supported by petioles in their centers. Both leaves and flowers are used to add a peppery flavor to salads
