About Mountain African Daisy

Osteospermum jucundum · also called Mountain African Daisy, Delightful African Daisy · flowering

Osteospermum jucundum is a rhizomatous herbaceous perennial native to the mountains of South Africa and Lesotho, producing solitary, light pinkish-purple daisy-like flowers 5–6 cm across with a contrasting dark eye from spring through autumn. It thrives in full sun with light, well-drained, moderately fertile soil and a warm, south-facing position. The key care point is to overwinter cuttings under glass in frost-prone regions, as the plant is only borderline hardy outside mild, coastal climates. Not confirmed toxic by ASPCA; exercise caution with pets.

Plant type: flowering

Watch for — Aphid infestations on new growth: Aphid colonies gather on young shoot tips and buds, causing distorted growth and sticky honeydew residue. Blast off with water or apply insecticidal soap; encourage natural predators such as ladybirds.

The reasons mountain african daisy isn't blooming

Almost every non-blooming mountain african daisy traces back to one of these, roughly in order of how common they are:

  1. Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
  2. Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
  3. The plant has not been deadheaded, so it stops flowering once it sets seed.
  4. Irregular watering — drought or waterlogging at the budding stage makes buds abort.
  5. It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding mountain african daisy a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get mountain african daisy to flower

  1. Maximise sun. Give mountain african daisy the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
  2. Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
  3. Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
  4. Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for mountain african daisy and get the feeding right with the mountain african daisy fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Mountain African Daisy flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full mountain african daisy care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.
