When it comes to pollination, you need to get to know how your plant flowers and pollinates. Some plants have flowers with all the parts needed for successful pollination. Other plants have separate female or male flowers on the same plant. Other plants have female or male flowers only on separate plants.

PC: Leslie F. Halleck

For example, holly plants have separate female or male plants. Only female plants of holly plants produce berries, once their female flowers are pollinated by pollen from a nearby male plant. For plants with separate sex flowers, you'll need a specimen of both for successful pollination.

Many plants can generate new root tissue (adventitious roots) and new shoot tissue (adventitious shoots) from other parts of the plant such as a stem or leaf. Once the new roots and shoots form from the existing plant tissue, a new identical plant clone develops. The resulting new plant will identical to the mother plant from which you took the cutting.

I accidentally broke this piece of African violet crown away from the rest of the plant. I supported it in water and rerooted the crown, making a new clone of the mother plant.

Mother plants are so named simply because it provides the material to grow the new baby plants.

A callus often develops at the base of a cutting at the site of a wound, when conditions are good for rooting. A callus will look like a knot or knuckle growing at the base of a cut stem or leaf.

This pepper cutting has developed a knuckle-like callus at the base of the cut stem; crown roots will soon develop.
PC: Leslie F. Halleck

Some plants will develop a callus and adventitious roots simultaneously, while other plants must first develop a callus first, before new roots can grow.

Nigella seed pods are quite beautiful and easy to collect; and the bounty of dark black seeds spread easily around the garden without your help. Ok, so they can spread all over the place in sunny locations! But they are beautiful and are one of my favorite wildflower seeds to collect.

Nigella is a example of a perfect flower - one that has both male & female parts, thus able to self-pollinate. Allow these fanciful seed pods to dry completely on the plant for seeds to be mature. Seed pods will turn completely tan or brown when ready.

Fun Fact: Nigella seeds are edible! Many people use them as a seasoning.

Many succulents can generate new root and bud tissue from the base of a fallen leaf. The leaf will typically form a callus, and then new adventitious roots will form, followed by an adventitious bud and new shoot.

Above, a fallen echeveria leaf develops new adventitious roots at its base, followed by an adventitious bud and shoot, which then develop into a clone of the original mother plant. Cool!

Certain plants, such as the popular houseplants peperomia and begonia, can develop new roots and buds on the leaf petiole and even from the veins along the leaf itself. These types of plants are masters of multiplication and can be propagated in a number of different ways.

If you look closely at the photo, you'll see a new adventitious roots and a new tiny bud shoot developing. This will turn into a new baby clone plant! However, don’t expect your tomatoes or citrus plants to sprout new roots from just a leaf; the cells in their leaf and petiole tissue can’t grow new root or shoot tissue.You'l need to get to know how your chose plant can, and can't, make new roots and shoots from cuttings.

New adventitious roots and buds can develop at the base of a leaf, leaf petiole, stem internode, node, or at the base where a stem has been cut, depending on the plant species. Have you ever been instructed to plant tomatoes deeper in the soil so that you bury part of the stem? That’s because tomatoes grow adventitious roots along their stems, which can make the plants stronger and more vigorous.

You can clearly see the adventitious roots growing along the stems of this potted tomato plant. These stems are good candidates to provide cuttings, since root tissue is already growing.

Can't get enough Chinese money plant (Pilea peperomioides)? Me neither! Luckily this beautiful houseplant is a prolific producer of baby plants, all on it's own.

Pilea can be propagated by removing these offsets, or pups, that grow from the base of the main plant stem. These pups develop their own roots and can be cut away from the mother plant and potted up.
