My Serissa shrub died completely back and went missing for a year, suprisingly enough as I was about to dig and replant that space, it has returned and grown to about 2 feet this year...I missed my Tree of a Thousand Stars

I have had Serissa foetida growing in an unsheltered outdoor location in a flower garden in Charlotte, NC for seven years. I am in zone 7a, and Serissa is not considered hardy here, but mine has consistently provided us with many beautful tiny pink flowers, and so far has not shown any damage from cold weather.

My serissa foetida floraplena is nice and healthy looking, just dropping the occasional leaf. It's not a bonsai. It's under lights 10-12 hours each day. But it will not bloom. About every third watering it gets fed a liquid feed of 7-9-5. Once in a great while I've tried a bloom-buster (10-54-10) out of deparation. I've been able propagate two plants from stem cuttings, so it's got some juice in it. But WHY WON'T IT BLOOM?

This plant is very easy to grow. I have had 2 Pink Snowrose variety bushes for several years now and they require no special care. They get the same balanced fertilizer everything else gets during the growing season. I do suggest you protect from wind as they will get windburn in winter and shead even more leaves. Afternoon shade is prefered also.

Actually I just got my Snow Rose yesterday. It's starting to let a few of its leaves fall, but I read somewhere that the Snow Rose is finicky when it changes environments. Well, if anyone would like to e-mail me any tips on my Snow Rose I'd really appreciate it. :) I'm at "[email protected]"

this plant is beautiful. i just acquired serissa "kyoto", what i see to be a darker-leaved variety with pink flowers, from Meehan's Miniatures, a fabulous Bonsai "company" based out of Maryland. i've had it a week, so no experience here. will post pictures.

seems a relatively easy plant to care for. keeping this one indoors.

I live in East Texas and purchased this plant over 5 years ago knowing nothing about it, except its name. It has best thrived in almost full sun (only slightly shaded by a vitex). I also have severl small ones that I have propagated from cuttings placed in different areas around my yard. It has survived in drought condition and 110 degree to almost 0 degree weather. It has never failed to flower as long as I have had it.

Common names: Snow Rose, Thousand Star, Star of June
Serissa Foetida are delicate bonsai that will drop their leaves if there is a drastic change in light, water, or temperature. A humidity tray is suggested but do not allow the water to touch the drainage hole in the bottom of the plant. This allows water to rise into the soil and may cause root rot. Misting is optional but not during the flowering season because it may damage the sensitive flowers. This tree is not recommended for a beginner.

A relative to the Coffee plant, Serissa is a favorite of bonsai enthusiasts. The species name refers to the fetid smell of the leaves and stems when bruised.
