Gardeners' Notes:


On May 30, 2015, Floribunda20 from Burlingame, CA wrote:

After years of this vine dawdling on an east-facing stucco wall in hillsborough, California, it erupted this spring, producing dozens of magnificent white trumpet clumps that, when cut, last for at least a week indoors. The vine is currently about 15' by 15', held up with support.
The twining ends are a beautiful addition to floral arrangements.
Caveat: when cut, ends ooze a sticky white sap. Good idea to hold them away from you to let them drip.

Only mature plants will bloom. Location is in full sun, with plant being dry by the end of the day. There are two distinct types of Beaumontias, and probably more. Grandiflora and Murtonii. Many nurseries at this point are only beginning to diffrentiate between the two, however they are quite different and have different needs.
B. grandiflora is from northern India- blooming once a year after a sustained period of cool winter months. It does not blooom in heat,.Its flowers are long and tubular or trumpet shaped
B. murtonii is endemic to the low lands of Thailand and is a repeat bloomer with very flat held wide-opened flowers that do not come in a trumpet shape..
If you are looking for a heat loving repeat bloomer then Grandiflora Murtonii would be the choice... read more

This plant grows year round outdoors in San Francisco. It's a fairly large woody vine, requiring a lot of space (at least in our tiny SF yards). The foliage is very attractive, and well, no more needs to be said about he amazing flowers. Well worth the space if you have it.
