Why Do Some Alpine Grasses Grow Baby Plants Instead of Seeds?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do some alpine grasses grow baby plants instead of seeds?

The Big Idea

Some alpine grasses grow baby plants instead of seeds because summers up high are short and cold! Seeds need time to ripen, and sometimes there just is not enough warm weather. So the grass finds a shortcut.

Short Summers

Step one: a short summer. In places where summers are short and cold, seeds may not have time to ripen. A seed that is not ready cannot grow into a new plant.

Tiny Plantlets

Step two: plantlets. Alpine bluegrass sprouts tiny baby plants right on its flower head, instead of seeds. Botanists call this trick live-bearing, or vivipary.

Fast Start

Step three: drop and grow. The little plants drop off, take root, and start growing right away. They are exact copies of their parent, ready to grow as soon as conditions allow.

A Closer Look

Let's take a closer look! This is the flower head of the grass. Instead of seeds, it grows tiny plantlets with little leaves. They drop to the soil and put down roots. Then they grow fast during the short summer.

Quick Facts

Quick facts! This trick is called vivipary, or live-bearing, in plants. The baby plants are exact copies of their parent. Plants that start fast have an advantage in short summers. Alpine bluegrass is tough and grows in cold, rocky places.

Think Like a Scientist

Now, think like a scientist! Sprout a bean on a damp paper towel inside a plastic bag. Check it every day and draw what you see. How fast does the root grow? Plants that start fast have an advantage in short summers.
