The Enemy: False–hellebore (Veratrum californicum) This lily family native perennial plant grows up to 4 foot tall, has thick rootstalks with very leafy stems that are sheathing at the base. The leaves are heavily veined and can grow as long as 12 inches. The plant is also called ‘Skunk cabbage’ as the leaves wrap around each other similar to how mature cabbage does. The plant produces a dense flower panicle with white to cream colored flowers. It may be as wide as three feet at the bottom but grows to almost a point at tip of the plants, losing density as it goes up. It generally can be found in moist areas such as creeks, marshes, and swamps such as the upper highlands meadows (like Grays Lake Area). It is very toxic to livestock as well as humans if ingested. Strategy: As this plant is keen to very moist areas it can spread rapidly within the meadows. Its worst issue is that it is toxic to any livestock, especially cattle and sheep. Illness can occur within a few hours of ingestion, and can cause birth defects. The plant is also very robust and will crowd out grasses and other broadleaf plants. THE DEFENSE: Mechanical control can be effective as long as you get most of the bulbous type of root. Plowing and disking is not effective as the plant has too much root. Very few herbicides are effective. 2,4-D needs multiple applications to be effective. Products with Triclopyr such as Garlon, Redeem, or Crossbow applied early in the year or in the fall after the first killing frost are most effective. But as this is a native plant, only control it if it is a weed, not just nuisance.
