Lavender is like the Holy Grail in the third Indiana Jones movie. The plant has all sorts of special powers. Only, there’s no need to thwart circular blades or cross an invisible bridge to find it (and you’re probably not going to live for seven hundred years if you do).

Pelindaba Lavender is bringing the therapeutic herb — and 200-plus products — straight to Bainbridge.

Last month, the San Juan Island-based business announced it would be opening a new product gallery downtown, at 102 Madison Ave., the former home of Embellish Retail & Design.

“With the steadily increasing demand for our elegantly packaged lavender products across the country, we are steadily expanding our physical presence off San Juan Island,” founder Stephen Robins said.

“We are looking forward to becoming part of another island community that is similarly committed to local agriculture, handcrafting and economic sustainability.”

Pelindaba Lavender was founded 17 years ago as an open space preservation project. Robins, a retired physician, fell in love with the land and set out to preserve it.

He had a couple of rules, though. He didn’t want to cultivate a crop that would compete with other area farms. He didn’t want to tax the water supply. He didn’t want to load up on fertilizer. But he did want to grow something that was economically viable.

“Lavender was the best of all of them,” marketing director Amelia Powell Baggett said, referring to the short list. “It’s a very pleasing product to cultivate.”

Today, Robins has 25,000 plants in the ground, with plans to add several thousand more.

“The thing that makes us unique is that we have such a wide product range that we use our own raw materials in and we make all ourselves,” Baggett explained.

Organic essential oil is the biggest seller, “the gold that we distill from the plants,” Baggett said, and the basis for almost all the products. Close behind are lavender hand and body lotion, lavender honey and lavender pepper.

“Everything we make, we make sure to have its basis in a known attribute or quality of the plant,” Baggett said.

As a doctor, Robins had initially been skeptical of lavender’s folkloric following. But he did his background research and became a believer, struck by the plant’s “many definitive properties,” now detailed in the product descriptions on the Pelindaba website.

Grand opening festivities are planned from 11 a.m. to 4 p.m. Saturday, May 7, with plenty of freebies.

“People will get to try our lavender cookies and lavender lemonade,” Baggett said. “And there will be samples for people to take away.”
