Dicots and Monocots

-
Monocots and dicots are the two major groups of flowering plants.
Jim Conrad's site, "Backyard Nature Home" explains the difference well.
 
MONOCOTS or Liliopsida include the grasses, wheat, barley, rice, corn - in fact a fourth of all flowering plants, one source says 199,350 species. Monocot seedlings usually have only one seed leaf or cotyledon when the seed sprouts. Their flowers have three petals or multiples of three petals.
 
DICOTS or Magnoliopsida
When you plant seeds of dicot plants, the first leaves to emerge will be 2 cotyledons or embryonic leaves. Dicots usually have four or five petaled flowers.
 
Monocotyledonae ("one cotyledon") and Dicotyledonae ("two cotyledons").
 
Didn't know this bit about the leaf veins "Leaf veins -- In monocots, there are usually a number of major leaf veins which run parallel the length of the leaf; in dicots, there are usually numerous auxillary veins which reticulate between the major ones. As with the number of floral parts, this character is not always reliable, as there are many monocots with reticulate venation, notably the aroids and Dioscoreales."
 
Thanks to UC Berkeley for the chart







MONOCOTS
DICOTS
Embryo with single cotyledon
Embryo with two cotyledons
Pollen with single furrow or pore
Pollen with three furrows or pores
Flower parts in multiples of three
Flower parts in multiples of four or five
Major leaf veins parallel
Major leaf veins reticulated
Stem vascular bundles scattered
Stem vascular bundles in a ring
Roots are adventitious
Roots develop from radicle
 
And this tidbit "Pines are conifers, and are neither monocots nor dicots. Only flowering plants are considered to be members of these two classes. This question is similar to asking whether a chicken is a monocot or a dicot; it is neither." Never thought to ask it about chickens, myself.
 
Princeton WordNet provided these examples of Dicots (ckick on any to be taken to the plant)

Moldy Tulip Bulbs

-

Moldy tulip bulbs are a big disappointment when you are hoping to fill a bed or some pots. It is not that unusual for their skins to have a bit of penicillin mold but these are beyond that tad bit stage. Mold penetrating tulip bulb  Mold on emerging tulip bulb growth  So, what to do? The plant references say to throw them out and buy new ones but I already spent $22 for 50 of these white tulip beauties. First, they got a soak in 1% bleach solution in the kitchen sink in the hope that the bleach would stop the mold from continuing to grow without killing the life force in the bulb itself. After a good slosh around, I wiped them off to see how much damage was beneath the blue and black.  This tulip bulb is soft to the touch and there is little chance it will thrive in the soil. This basal root on these have been ruined by mold. The final step I took to try to salvage part of them  was to spray them thoroughly with fungicide.  They are all planted in the

Propagate Begonia Stem Cuttings in water - Cane-like Angel Wing Begonia

-
Image
Propagating by stem cuttings is just about the easiest way to make more begonias for next summer's garden. During the fall, I regularly trim off 3-node long cuttings and put them into the growing pots where they take root. Now that cold weather has arrived, I root the stem cuttings in a vase of water. It's a great way to produce more pots of Begonias for next summer's garden. Water the plant well the day before. Take a cutting about 4-inches long, with 3 nodes, from a healthy stem. Use a perfectly clean container. Rinse the container with a drop of bleach if you are uncertain about its spotlessness. Remove all but the top leaf or two. There should be no leaves in the water. The cutting should  have a healthy leaf node at the bottom. Don't leave a stub below the node. Place the cutting into the water, and place the container out of the sun. In a couple of weeks, you will see new roots beginning to form. Check the water periodically to make sure it is still f

Create Nesting Areas for Birds and Wildlife

From the website, Choose Natives , this lovely and instructive article helped remind me to continue to increase the amount of habitat and nesting that we provide in our garden. Many, though not all, are native or considered to be native in Oklahoma. So, I did a little research on each recommended plant and provided a link to more information. You'll see the plant name in italics - those are my links for your edification. Here's the post Derek Stoner, Project Coordinator for the Delaware Nature Society, helped restore the 860-acre Middle Run Natural Area by “intensive habitat management”, including planting 12,000 trees and shrubs.  His lecture, ‘ Native Plants for Nesting Birds: Connecting Flora and Fauna’,  given to a group of enthusiasts at the Millersville Native Plant Conference   in Pennsylvania, focused on his observations. Here are Derek’s landscaping recommendations for attracting birds: Plant shrubs in clusters (“habitat circles”) that will create the dense
