Want Them All

Looks like New Guinea Impatiens (impatiens hawkeri) to me, although I've never seen one that big! They are annuals here, and don't get much more than a foot or so high. Where did you take this photo? Can you show the trunk and branches? How big was this one?

Want Them All

I don't have any other photos of it. The spread was about 5' in diameter, height about 4'. They are growing in front of a hotel in San Simeon, CA.

Very cool. Thanks for posting. It's cool to see what our 'annuals' look like when grown in ideal climates. Most are not annuals at all.

That looks like one of the many strains of Periwinkle to me. I have them growing around here too. I've got three of the colors. One is pure white, one is pink and the third one has a multi-colored flower.

You are thinking of Madagascar Periwinkle - Catharanthus roseus.
Compare:
New Guinea ImpatiensPlants of Hawaii: Impatiens hawkeri (New Guinea impatiens)
Periwinkle Catharanthus roseus - Wikipedia, the free encyclopedia
catharanthus roseus - Google Search

That is true! The Periwinkle, for example, can be trained to become a rather large, woody, ever flowering bush here. I like them. Only problem is that the flowers are easily propagated and you will find them coming up all over the place especially if the tradewinds are strong and they start coming up in the neighbors yard!

It's not a periwinkle, but impatiens.

Recently, Home Depot has been selling one they call "sunpatiens". Much stronger and robust than the N. G.'s.

Most likely a New Guniea Impatient, since vinca do not have the
long nectuary behind th flower. I also looked at one of the pictures and it
shows a seed pod developing and that certainly looks like what
develops on an Impatient.

Too big and vigorous - and alive - to be a New Guniea, around here anyway. They hate our heat and humidity.

Check out the links I posted above. The Periwinkle mentioned is not vinca, but Madegascar Periwinkle - Catharanthus roseus.

The plant shown in the photo is New Guinea Impatiens. The flower structure including nectary is identical and the leaves are identical. Sunpatiens are a new breeding, and as the link says, they stay small.

coast crab - it seems unusual that New Guinea Impatiens (I. hawkeri) would not like hot humid conditions, since it is native to New Guinea.

Want Them All

The city where these photos were taken, is known for cool and foggy summer, it's NEVER hot, the city is right by the coast.

I'm very familiar with the periwinkle you mention and know that it's not vinca, we plant hundreds ever year.

They may say that sunpatiens stay small, but I've planted them and seen them waist high by the end of the summer. The dark purple stays smallish, but not so much for the others, especially white and the hideous orange one.

Are New Guinea impatiens really from New Guinea, or is that a gimmicky name like Madegascar Periwinkle? (please don't feel like you have to look that one up because I really don't care, it's just to make a point) All I know is that they rot out as soon as the nights get hot. Fact is that sunpatiens and New Guineas look EXACTLY the same in the pots at the garden centers, the only difference is the price (sunpatiens are expensive) and that one will live and thrive and the other won't.

This thread is simply to identify the photos in the first post. The photos are of Impatiens, and I believe they are from New Guinea. (Btw, Madegascar Periwinkle is in fact from Madegascar too). The SunPatiens that you mention are hybrids using Impatiens hawkeri and related species, which is why they look the same. SunPatiens are just bred for different conditions. New Guinea Impatiens and SunPatiens are essentially the same, except for the culture and size. I don't have any personal experience with them, but that is just what I have read. If your experience is that the SunPatiens are large, then the photo could be either of the two.

It doesn't matter where they were grown either - this is about plant identification. By comparing the flower structure and the leaves, I can't say 100% if these are the New Guinea Impatiens that I have always known, or if they are the new breeding of the SunPatiens, but it's close enough. I did not know about the SunPatiens before this post, so thanks for that info. Maybe I'll try some next year.

Want Them All - is that enough info for you? Hope it helped.

some of the pictures are a little dark, but it sure looks like new guinea impatiens to me. Possibly a plant they overwinter in the hotel lobby? They're pretty easy to overwinter

It looks like Impateins Sodenii Ssp Oliveri to me. That gets big! so does Plain Sodenii Var Sodenii. Roots dead easy in water if you wanted to try it.

I planted a sunpatien a sunny area but it got a lot of shade too. The thing just melted after a week. And just 2 feet more in the shade are some regular NG impatiens that are still alive today!
