Growing a Gardenia

Asked March 6, 2018, 12:46 PM EST

In a garden catalog 2 types of Gardenia are listed. The first is called a trailing gardenia (jasminoides 'Radicans") and the other is Summer Snow gardenia hardy below 0 degrees. Can either of these grow/bloom in the Portland area?

Thanks for contacting Ask an Expert with your gardenia question.

Both these plants are different types of the overall Gardenia jasminoides family or cape jasmines.

‘Radicans’ is generally considered too tender to grow outdoors in your area. It could be hurt by temperatures in the 20s. However, if you are in a warmer part of the metro area or have a protected spot, you might get by.

Summer Snow Gardenia is a hardier sort, able to withstand temperatures down to zero. It should do well in your area. Give it a well-drained spot, and water it well in its first year, for a good start.

Have a great (and fragrant) gardening year,
