Podranea ricasoliana - Pink Trumpet Vine in Balboa Park, San Diego

They need short days to bloom. Unfortunately, our recent frost did for our flower buds. Likely no more bloom until next fall.

Tugbrethil:

This vine doesn't need short days to bloom...it blooms all summer long. I had one for many years...it bloomed from spring - fall...with peak bloom in summer.

They are so pretty and lovely shape too.

Wonderful colours :o)

Wow, Delonix! It never blooms before September or after March, here in the Valley of the Sun. The heat must have more effect than I thought.

Sixpence, Terratoonie:

Thanks! :>)

Tugbrethil:

It is a very heat-tolerant vine...however, when you have 105ºF/41ºC temps at 1 or 2 a.m...and temps rarely falling below 95ºF/35ºC. for many months...I think it has major affects on the flowering.

I do know that the Cape Honeysuckle (Tecoma capensis) can bloom year-round in your area, while it blooms the same as the Podranea here. It does produce tiny flower buds that abort, in summer.

Tugbrethil:

Cape Honeysuckle (Tecomaria capensis) does bloom all year here...however, it's heaviest bloom is in the fall, winter months here in San Diego.
