Bear Grass

Bear-Grass is the only evergreen member of the lily family. Its flowering stems grow from off-shoot plants growing at the base of each “grassy” clump and appear at each plant every five to ten years. The flowers are large (approximately 3” X 4”), blooming at the tops of stalks that are around four and a half feet tall. The genus name comes from the Greek word xeros meaning “dry,” and phyllon meaning “leaf” and the species name tenax means “holding fast”, referring to the tough pliable leaves which were used by the indigenous people to make ornamental baskets. The plant is poisonous although some think that bears eat the fleshy leaf bases in the spring. I’ve never seen bears eat it, but I have seen grassy bases that have been severely disturbed in the spring. The plant is native to six of the far western states in the U.S. and the two western provinces of Canada and in this area usually likes elevations over about 5,000 feet.

You can find a wealth of information on them here .

  1. Reading some of the rangers’ comments from Glacier Park, just where and how profusely this will appear each year can be a mystery. Seems like it must grow in cycles, meaning that wherever people find a lot of it one summer may have very little the next. Is this similar to where and when you find it?

    • I’ve seen that too but I have no idea what causes it. I would guess the weather conditions, especially during the previous winter, have a lot to do with it.

      • After I got interested in native plants in 1999, one of the lessons I learned by 2000 is that a place that haa lots of wildflowers of a certain species one year might have few or even none on the same date the following year.

        • Many of them have cycles that we don’t understand. Many berry producing plants are like that too.

  2. Beautiful! Thanks for sharing as it’s not something we get to enjoy in Ohio.

    • This one really beautifies the mountainsides up high this time of year. I hope I will be able to find them in the abundance that the sometimes have. It’s an amazing sight.

  3. I imagine a bear just waking up in spring would be hungry enough to eat just about anything. I’m glad that they didn’t get these examples though, because they’re beautiful and unusual.

    • Bears do have to exist and even gain weight on nothing but leaves, grass and roots for most of the summer and then put on extra weight for winter when the berries ripen, so they know every edible plant in their territory. Personally I doubt that they do eat this one because it’s leaves are tought enough to use for basket making.

  4. I’ve only ever seen this in the States, not in Canada (not saying it doesn’t grow here). It’s quite a unique shape.

  5. What a lovely flower. They’re so unusual and remind me a little of our swamp lily.

    • They are unusual wildflowers because of their very large size, but some years they simply command the higher elevation mountainsides; quite a sight!

    • To the best of my knowledge their range is only is the far western parts of the US and Canada. I wish you could see them though!

  7. I remembered the name, but i’d forgotten how lovely and unique the plant is. I read that their bloom cycle is quite irregular, and can be anywhere from five to ten years. If that’s so, it’s nice that there are so many of them, so you can enjoy them every year. They’re bigger than I realized, too. A whole mountainside covered with them has to be a remarkable sight.

    • In the nest few days I’m going to see if I can find an area where thery cover the landscape: if I can’t find one I’ll post some photos from precious years. They are a spectacular sight.

  8. Some of these look to my imagination like fireworks going off.

    • The very tall stalks on which the flowers grow adds to that appearance. I’ve seen many over 5 feet tall. Some large clumps remind me of the climax of a fireworks display where the sky is full of bursts.

  9. Hi Montucky, I don’t think I have ever seen any of this plant although perhaps I had and not known of it. Beautiful plant with those fluffy blooms. Have a wonderful coming week!

    • They are some of our largest wildflowers, but they like higher elevations, usually over 5,000 feet.
