Viburnum tinus? I cannot find a description of the flowers being malodorous.

Here is a link that might be useful: Viburnum tinus

Yes, it's Viburnum tinus. They are extremely common in my area and with such a long bloom season, they are particularly noticeable. And while I personally don't detect an unpleasant aroma - scents are very subjective - I've heard them described as smelling like anything from old sweat socks to week old garbage to paperwhite narcissus!

The species is reputed to be self-incompatible and requires another seedling or clone for good fruit set. 'Spring Bouquet' (syn. 'Compactum') tends to be the most common cultivar in my area, has the dark red buds shown in the photo and generally stays right around the size noted, so very likely the plants in question are this selection. FWIW, I've frequently seen hedges of V.t. 'Spring Bouquet' full of dark, nearly black berries so there's no reason to assume multiples of the same cultivar won't provide adequate cross pollination. Also, I've never seen the berries favored by any particular wildlife and they do tend to be rather inconspicuous as well.....this is not a Viburnum I'd put at the top of my list for berry effect.

Ah! Yes, I found this info on Paghat's garden:"These pink round buds will open in March & April into white mildly honey-scented flowers, & it will continue to be in bloom through May, though toward the end of their bloom the odor becomes terribly unpleasant for three or four days while it is most eager to attract pollinating flies. "
I do have 3 other viburnums that I use more favorably for berry production, but since these were already there, and the hubby is not agreeable to digging them up, I figured I would try to work with them. Any idea what would cross-pollinate them (what other viburnum blooms at that time of year)and where I could get one? These 4 shrubs have never set berries. The mockingbirds do like to nest in them every year since they are so dense. Thanks!

Also wanted to say thanks for answering my questions! I have so much appreciated the info I've gotten when I post.

Distinctly different clones are on the local market at this time as 'Spring Bouquet'. There are also other bushy cultivars of laurustinus being offered at general outlets here these days, so there may be more than one present where you are also. Visiting some nurseries may result in making a match - keeping in mind that apparently some stock on the market under the name is 'Spring Bouquet' and some is not.

Your grouping of plants should produce berries. If not, look for another compact form of V. tinus - either 'Spring Bouquet'/'Compactum', 'Evie' or 'Spirit' - to plant alongside.

But like I stated previously, this is not a selection of viburnum I would grow specifically for the berry effect - it's primary desirabiity is its versatility in the landscape (in climate appropriate areas) and its very long bloom season.
