Hundreds of wildflower species grow on Midpen preserves. Visitors may see a variety of plant species blooming from early spring all the way through the later winter months.  Spring brings the highest frequency and diversity of wildflower blooms which generally peak during March, April, and May. 

Sunny, grassland trail sections are typically the best places to see spring wildflowers, but they may be found in a wide variety of habitats. The best locations and dates of the local spring wildflower bloom change from year to year depending on the amount of rainfall, how late it occurs, and when the temperatures start to increase.

In some areas, wildflowers are blooming more profusely as a result of the District’s resource conservation efforts, aimed to ensure long-term protection of natural and cultural resources on Midpen preserves.

Wildflower Viewing Etiquette 

Wildflowers can be quite fragile. Please follow these simple guidelines to make sure everyone can enjoy their beauty as they bloom.

  • Stay on established trails. Visitors venturing off trail can trample wildflowers and their habitat, preventing other visitors from enjoying the displays. When soils become compacted this prevents wildflowers from growing in these areas in the future. Please tread lightly and don’t DOOM the BLOOM!
  • Take photos not flowers! Wildflowers wilt quickly after picking and can’t be transplanted elsewhere. Picking wildflowers also prevents them from going to seed, which limits future wildflowers blooms.  Please do not pick wildflowers and allow other visitors to enjoy their beauty.
  • Take photos OF flowers not IN flowers. Photographs must be taken from the established trails only. Sitting in the flower fields will damage existing blooms and prevent the next generation from growing.
  • Follow rules of the preserves/parks you visit.
  • Enjoy! The blooms of spring don’t last for long each year. But don’t despair - wildflower seeds develop after a flower blooms and when left alone will to drop to the soil to provide next year’s blooms. The wildflowers decompose and provide nutrients to the next generation of plants.
