Can anyone identify this plant that I found growing in my backyard?

It has a thin stem, long thin leaves that are paired on the stem, with a prominent central rib on the leaves.

  • Knowing where you live would help in identification. Are those three spiky ball-shaped objects part of the same plant?

    I'm in Santa Clara, California. And yes, they're part of the same plant.

    These plants grow wild and weedy here in South Africa. Despite looking quite intimidating, the spikes on the balls are soft.
