Weekend Science Fun: Anticipating Spring With Flowers

After the cold weather, isn’t it time to think about spring? Bring a “springy” feel into your home with flowers. Children will benefit from the opportunity to observe plants and flowers up close, as well as enjoy their colorful beauty.

Houseplants
One way to have flowers during the cold months is by growing houseplants that bloom. I still remember the way my grandmother’s Christmas cactus erupted into a riot of red blossoms every winter, even though it was over thirty years ago. She also grew African violets in a wide variety of colors. She often took the leaves that had been knocked off or trimmed and started new plants by dipping the stems in water. You can use fallen African violet leaves as an opportunity to teach about plant propagation.

Our family has been watching one of our orchids for the last few weeks. It put on buds and then a few days ago the first flower opened. Since we had been babying the plant for over two years, we felt a sense of accomplishment. We learned that orchids have very different requirements for growth than some of our other houseplants.

Bulbs
Another way to bring spring inside is to grow bulbs indoors. A great favorite are the amaryllis. I often buy them after holiday sales when they are cheaper, making sure the bulbs still look firm. They grow fast, so they are a good project for young children who are impatient for results. Here in Arizona they can be set out into the garden to grow and bloom another year.

To add some science to the project, have the children measure the plant every day or every other day and record their results. Try to find out where amaryllis plants are found in nature, and what their natural environment is like. Plant several bulbs and grow them under different conditions to see which they prefer. Finally, you can get bulbs that are different colors and see if they grow any differently under the same conditions. We’d love to hear what you find out.

Other bulbs that can be grown indoors are tulips, daffodils, hyacinth, narcissus and crocuses. Most of these bulbs need a cold period before they will bloom, so make sure they have been properly chilled before planting.

Cuttings of Outdoor Plants
Bringing in branches of flowering trees and shrubs and putting them in a vase is another wonderful way to have some early spring flowers. Wait until a day when the temperature is above freezing and then cut a few branches from your forsythia bushes, pussy willows or fruit trees. Try to get branches with nice plump buds. Remove any side branches at the base that will be under the water level and then place the cut ends in a vase of warm water. Keep the vase filled with enough water, and you should have flowers in about two weeks. This is a quick project that doesn’t require a lot of effort, but that result in a lot of enjoyment.

Maybe this video of forsythia will inspire you.

Other activity suggestions:

  • gather an assortment of different plants and learn about differences in plant families and their flower structure
  • draw the flowers for an art project
  • study plant parts (anatomy) by identifying the stems, leaves, roots, etc.
  • explore plant propagation techniques

If you would like more details on any of these, please let me know. Hope you have fun!

Plant of the Week: Lupines

The rain we’ve been having lately has popped a bunch of seedlings in our yard.

I’m always excited to see these seedlings coming up, because I know in a few short months the seedlings will grow into showy flowers called lupines.

Lupines are fun because they self-seed readily. I first planted these over 15 years ago and they have come up every year since. On the other hand, they have not spread aggressively to other areas; they stay right where I put them.

The name lupine is thought to come from the idea that lupines were like “wolves” (lupus) eating all the nutrients out of the soil, because they always seem to grow in poor soil. Now people have realized that these members of the pea family can make their own nutrients in conjunction with bacteria found in nodules on their roots.  Thus lupines can grow in soils that are too poor for other plants rather than causing the soil to be poor. I’m not sure what that says about our yard. ☺

Lupines are fascinating to children because the hairs on the leaves catch raindrops and leave perfectly round droplets of water shining like gems.

Down side:  If you are thinking of planting lupines, be aware that the foliage of some types are poisonous.

Check the color of these flowers.

Now look at the centers of these.

Are they a different species? No, lupine flowers change color when they have been pollinated. Bees are attracted by the white centers of un-pollinated flowers, but ignore the red-centered ones (bees don’t see red). Lupines “talking to” bees, cool!

The sight of the lupines coming up always reminds me of the book Miss Rumphius by Barbara Cooney. In this popular book, the main character spreads lupine seeds so that the flowers bloom everywhere. So check out a copy and you can enjoy the beauty of lupines any time.

Plants Are Growing

After the posts last week about pumpkins, I received a question about whether a fresh pumpkin seed (that came directly from the pumpkin) would grow if you planted it. Here is the answer:

I planted these seeds last week after I took them from a fresh pumpkin. Looks like they are more than capable of growing. They are planted in moist potting soil in a newspaper pot.

By the way, the question was a good one because some seeds, for example apple, pear and blueberry, need a cool period ( a winter dormancy) before they will germinate.

November is a good month for gardening in Arizona. We plant many what we call “cold season crops” at this time of year. Lettuce, broccoli, cabbage, brussels sprouts, carrots and chard can all withstand the slight frosts we get here in the winter, and so go into the ground now.

The basil in this photograph does better in the warm summer months, but will make it through if we don’t get a heavy frost or if someone remembers to cover it.

Hope everyone has a good week. I think I’m going to go make a salad.
