this type of plant has it's complete life cycle, seed to seed, during a single season and then dies at the end of the season. ex: marigolds and zinnias
it takes this plant two seasons to go from seed to seed. dev roots and leaves first season and grow flowers and set seeds during second. die at end of second season.
coloful leaves surrounding the flower. ex: poinsettia
any plant with an enlarged underground storage organ.
place inside seeds that contain the nutrients needed to grow which are wrapped around the embryo within the seed. in many plants the cotyledon opens to form transitionary leaves.
the spot where its roots and stems meet.
the variety. a plant that has been selected or bred to have a specific trait or traits different from other members of its species and that has been given a unique name.
when an annual plant finishes making seed for the season it will stop flowering because it has completed its biological mission of reproducing. you can keep the plant blooming longer by plucking off flowers that have passed their prime.
planting seeds outside right where you want them to grow
can make 2 or more plants from dividing or breaking it into several pieces. rec for certain perrenials like hostas. best during dormant period while plant is inactive.
all in the petals. single flowers like daisies have one row of petals around the blossom's center. Double have a second or third or forth ring of petals completely overlapping the first. if don't overlap called "semi-double."
process of splitting parts of two or more plants together to make one plant.
a plants habit is its direction of growth. plants that grow up have an upright habit. one that grows along the ground has a 'prostrate' habit
you get a new tree/shrub but the place you want to plant it isnt ready. keeping it healthy until you plant it. put plants rootball in soil and cover it lightly. water occasionally and plant can stay there for quite a while (weeks even months)
- 1) any organic matter like leaves or wood chips.
- 2) organic matter that has decomposed to the degree that its no longer distinguishable from soil
plants that grow from cross-pollintaed seeds. next generation called f1 hybrids are uniform like parents. however seeds from f1 will not grow a uniform next generation
a way to describe a flower that is made of many flowers
soil that contains silt, sand and clay (major components of well balanced soil)
a bulb that adapts well to the kind of soil you have, your winter and summer temps and the amount of light it gets.
live longer than 2 years (even through frozen winters)
- helps direct their growth, make it bushier.
- soft pinch=half inch
- hard pinch=inch
do before plant has committed to flowering
- plant sex
- for the plant to produce seed, tiny dust-like grains of pollen contained in the anthers (male organ) must reach the stigma, where they burst open and release sperm that fertilize the egg within the ovary (female organ)
annual and biennials that produce and drop seeds where they are growing. hollyhocks
desirable trait created by spontaneous mutation of cells
underground stem on which new plants grow
a bud that forms and grows into a branch in the crotch between another branch and the main stem
the first root many plants put down when they germinate grows straight down into the soil and is like a stem that all the other roots grow from
process of reproducing a plant in the laboratory into replicas of the original plant
leaves that have different colors...if genetically created.
