Pretty flashy, but it has character that will come through even after the the color fades. It's a Japanese wisteria (Wisteria floribunda) that belongs to Tobie Kleynhans.

The Happy Accident in the title is from a post we did two days ago that features bonsai by Tobie Kleynhans. Just so you don’t misunderstand, it was our discovery of Tobie’s bonsai that’s the accident, not his bonsai, which are the happy part. Tobie lives and practices bonsai in South Africa.

Bastard olive. Tobie lists this as a False olive (Buddleja saligna). To quote Wikipedai.. Buddleja saligna, the false, or bastard olive, is almost endemic to South Africa where it has a wide distribution. It occurs most often in ravines and against outcrops, and is distributed from coastal elevations to the central plateau at elevations of < 2000 m. The species was first described and named by Willdenowin 1809. It is stricktly South Aftican.

Bougainvillea Peruviana. One of about 18 species of Bougainvillea, a native South American genus.

Another False olive (Buddleja saligna), though quite different than the one above.

I like this one. Even though it's a Juniper, it reminds me just a bit of the towering* White pines (Pinus strobus),  a dominant tree in much of the Northeastern U.S and Eastern Canada. It's a Sargent juniper (J. chinensis) - probably Shimpaku, but I can't tell for sure.
 * towering by East Coast standards
