Finishing Times for Stephanotis

We cannot give you set finishing times.

If you want to sell plants with flowers, you will see buds form in late Spring and Summer.  The earlier you plant the plugs, the larger the plant will be when it starts to bloom.  Older plants tend to produce larger umbels of flowers.

Most potted plant growers do not sell these plants until they flower. So these growers plant in Fall or winter, pinch a few times, stake, and sell through the following Spring and Summer as they bloom.

Outdoor nurseries sell green plants year around in frost free zones.  One plug will finish a gallon pot in a year, on a 3 foot stake.

We have seen plants as small as 3 pairs of leaves bloom.  However, most plants do not bloom until they have vines several feet long. To encourage blooming on smaller plants, one trick is to plant in the Fall, pinch after two leaves, and allow the plants to grow “cold” through the winter.   A cool dry winter promotes flowering on all plants when they resume rapid growth on warm Spring days.

We have not seen any increase in blooming with applications of growth regulators.
