No coddling required. Unless you are in a dry climate it shouldn't need watering more than a few times after planting. And they're easy to propagate if you want more.

Is it a microphylla...with that extremely bizarre bubblegum fragrance, I love philadelphus and have a couple on the allotment. I didn't bother pruning overmuch - they flower on older wood anyway, but if I do, I tend to cut back the newly flowered shoots as soon as flowering is done. and thin out the old wood every 4-5 years or so...but you could easily just leave it to its own devices with no lack of blooming. I am terribly tempted by the new to commerce pink flowered variety.

Ah, now I am wondering if we are talking about the same thing as choisya is also referred to as mock orange...which is one of the easiest shrubs ever (although not keen on the scent of the flowers).

OP ist in 5b so I don't think Choisya would grow. And Minnesota Snowflake is a cultivar of Philadelphus.

Default here is Philadelphus.

The usual question is 'why doesn't my mockorange have fragrance?'. My personal question was 'why doesn't my mockorange bloom?' My other garden has HUGE ones that are covered with flowers even in deep shade.

They grow on the sides of the roads here in wooded patches and unkept (and unkempt lol) fields etc, so I don't think they need much human intervention.

MG is right about the fragrance, or lack thereof. There's a current thread about that now. About five years ago, the first (and almost only) year that my mockorange decided to put out a fragrance after at least 15 if not 20 years of absolutely no smell whatsoever, was the very first time I had ever actually smelled a mockorange. It was divine and I could understand the hype. The next year, I was walking down my road when I was stopped in my tracks but the most glorious smell. I knew it had to be a mockorange, and sure enough there in amongst the scrub trees and all the other "stuff" growing along the side of the road, was a mockorange. Now, if mine hadn't bloomed the year before I would have never known what to look for.

I often try to remember if I had smelled that particular shrub before and just never knew what it was, or if it too never smelled lol. After all I had walked by that thing for 25 years before noticing it. Last year the electric company ravaged my street (well, all the streets in the region) by cutting down trees along the roads that might interfere with wires, and the trees all around this mockorange are gone. It got quite a bit of sun before, but now of course gets more. I drove by it twice a day while it was in bloom last week or so, and always opened my windows to try to get a sniff lol, but never had a chance to walk down to it. It will be interesting to see how and if it grows much bigger or blooms better without the tree canopy.

P.S. Mine is in bloom now and sadly, no smell.
