Houseplant Hints – Streptocarpus

Streptocarpus is a beautiful plant that is closely related to African violets and it grows in similar conditions. Also called Cape primrose, streptocarpus blooms almost continuously if given the right conditions. Most of the hundreds of hybrid varieties available bear trusses of pink, white, purple, or red flowers, often with contrasting white or yellow throats. With the exception of providing cooler winter temperatures, treat it as you would its cousin, African violet. Streptocarpus are popular, relatively inexpensive, moderately easy-to-grow houseplants in a wide range of attractive colours which will produce flowers over several months. They are also easy-to-propagate.

 

Spring/Summer Plant Care

  • Keep in good light but do not expose to hot sun; an east or west facing windowsill is ideal
  • Plants in the greenhouse or conservatory will need some shade and good ventilation
  • Water regularly from March onwards. Plants can be watered from above or below, but don’t allow the pot to sit in water
  • Feed at two weekly intervals. Use a high potash plant feed at half strength from March to September or a specialist streptocarpus food
  • Remove dead flower stalks at their base
