Fall through spring in milder climates.
- Alaska Series - Bushy, dwarf plants with heavily variegated foliage and the blossoms are held above the foliage.
- Jewel Series - Bushy, dwarf with double and semi-double blooms. A profuse bloomer, but flowers can tend to get lost under the foliage.
- 'Peach Melba' - Busy, dwarf with semi-double buttery yellow flowers splashed with orangy-red centers. Good for containers.
- 'Canary Creeper' (T. Peregrinum) - Perennial vines with yellow flowers that look like birds wings.
- Nasturtiums like regular weekly waterings. They will survive some drought conditions, but flowering will diminish and the foliage can begin to look ratty.
- Deadheading is not usually necessary, unless a plant has been stressed and is holding on to spent blooms.
- They do, however, thrive in lean soil. Dont feed nasturtium plants at all during the growing season. Fertilizer causes them to put out more foliage and less flowers.
Pests & Diseases: Nasturtiums are very prone to aphids and are sometimes used as a trap crop in vegetable gardens. A strong blast of water is usually enough to get rid of the aphids. They can also be prone to flea beetles, slugs and the caterpillars of cabbage white butterflies.
