DIY 178

Nemesia are good flowers for rock gardens, containers or for use as a bedding and front of border plants. Surprisingly they also make a nice and useful cut flower.

Nemesia Culture

  • Nemesias grow from 1 to 2 feet tall, with sparsely branched plants. They grow erect, with the flowers carried in large clusters at the top.
  • Nemesia are available in a wide color range, including yellow, orange, brown, pink, red, and lavender-blue.
  • Thompson & Morgan seed selection
  • Nemesia are half hard annuals you can sow now or buy as mini-plugs in May.

Growing Nemesia from Seed

  • Sow seeds indoors 4 to 6 weeks before the last frost date.
  • Seeds germinate in 7 to 14 days at 55 to 70 ยบ.
  • In areas with cool, dry summers, seeds can be sown outdoors as soon as the ground begins to warm
  • Nemesias like fertile, well-drained soil and prefer full sun for flowering but cool evenings.
  • Nemesia will tolerate partial shade.
  • Transplant seedlings 6 inches apart after the last frost date.
  • Pinching the tips of seedlings increases branching.
  • Nemesia are useful for edgings, in rock gardens, walls, and for borders.
  • They are splendid container plants and make good cut flowers.

Nemesia Varieties.

    • There are three main species Nemesia caerulea, Nemesia foetens, Nemesia fruticans
    • Nemesia Masquerade are extraordinary with coconut-scented blooms! An unusual variety with exotic-looking yellow-and-white blooms. Plants are easy to grow, ideal for beds or containers and will bloom 12″ tall right up to first frosts.
    • Nemesia denticula Confetti or Celebration are popular tender perennials distinct from their half-hardy annual relatives producing lots of attractive flowers throughout the summer. The plants prefer moist but loose sandy soil. Extra watering may be needed in a dry season. They look equally good planted in the border where they are good for planting at the front.
    • Fire King is a scarlet-flowered variety. St. George is white and deep red bicolor.
    • Nemesia versicolor is a similar, more compact species. It has a variety of colors including truer blues. Blue Gem is a very compact variety growing to 10 inches high with blue flowers. Nemesia caerulea (below) is available in true blue, lavender, and white.
    • I also like the Nemesia Tapestry or the blue and white KLM series from Thompson & Morgan

My Nemesia Tips

      • Nemesia grows 10″ high on unassuming plants
      • The flowers start blooming in June and last through August. Try the self colour varieties.
      • Sow seeds late winter to mid spring at 55-60F in a good seed compost on the surface of compost and gently firm down.
      • Keep soil damp but not wet. Do not exclude light and do not let the soil temperature become too high
      • Germination usually takes 7-21 days.
      • Transplant seedlings in to 3″ pots as soon as they are large enough to handle.
      • Gradually acclimatise to outdoor conditions for 10-15 days before planting out in a sunny spot after all risk of frost has gone
      • Plant close together for a mass of colour
