What is a wildflower?

- Grow freely

- No human intervention

- Uncultivated environment

Native vs. Introduced

- Evolved in the region: Native

- Live but don’t evolve: Introduced- Detrimental to ecosystem

Types of Wildflower

- Annual- bloom for about two months and die with the first hard frost. They are more common

in wide open spaces without trees. They are “self-sowing” because right before they die they drop their own seed, so when the next year comes around, a new one grows. Ex: Red Poppy

- Perennial- flowers that come back each year from the same root system. Rarely grow in

their first season. They usually bloom in their second growing season and this bloom only lasts a few weeks. Perennials have been known to live to return for decades, even centuries. Ex: common daisy

- Biennial- like perennials, they do not bloom their first growing season. But unlike

perennials, they only have two growing seasons. They have a two year life cycle, wherein the second year they bloom and seed a lot for a few weeks. Ex: Queen Anne’s Lace.

Photosynthesis

Primary Producers

Carbon Dioxide + Water→ (light) Sugars + Oxygen

Wildflower Parts

Reproduction

● Transfer Vectors.

● Pollination ○ Cross Pollination

● Fertilization

Flowers on Campus

- More plants near a water source

- Nutrient rich soil- Soil is more permeable

- Places close to a climax community

- Riverbank by the Carter field- Behind the Scout Hut- Behind the Denny field
