Plant I.D.

ajrevell18

New build landscapers planted a row of shrub on our plot. 

The plants have taken well, flowering white during the summer. I am wondering what species they are in order to purchase some more. The landscapers say it is Ceanothus, but I am wanting further clarification.

See the attached images.

Asarum

They look like Escallonia to me. 

Athelas

Same here, if white flowers then likely Escallonia ‘Iveyi’

Best to remove any leaves with yellow/black spots (I can see a couple in your photos) and to pick any off the ground as well. I lost my Escallonia plants to leaf spot this year.

Thanks for both your comments/advice.

I'd agree - Escallonia.
The white one [Iveyi] isn't as tough, so if it's that, and you're in a colder, wetter area, it's unlikely to thrive.
