The offspring of two true-breeding plants is also true-breeding, meaning they will consistently display the same traits as the parents. This is because true-breeding plants are homozygous for a particular trait, so when they are crossed, their offspring will also be homozygous for that trait.
If two true-breeding pea plants are crossed their offspring will show the dominant trait. The flowers will be purple or light purple.

Mendel crossed true-breeding pea plants with contrasting traits in his first generation experiments. Specifically, he crossed a true-breeding purple-flowered plant with a true-breeding white-flowered plant.
All the offspring were purple because Mendel was dealing with simple genetic dominance. The purple true breeding parent was homozygous dominant and the true breeding white parent was homozygous recessive. When those two are crossed they create only heterozygous offspring (look up a punnett) and since this is simple dominance those heterozygous will show the phenotype of the dominant allele which is purple.
because it helped Mendel discover which plants would be crossed to produce offspring.
When two true-breeding plants are crossed, the offspring will inherit one allele from each parent for a specific trait. Since both parents are true breeding, all offspring in the first generation (F1) will exhibit the dominant trait, assuming the traits are determined by simple dominance. If the F1 generation is then self-crossed, the resulting F2 generation will display a phenotypic ratio that reflects the segregation of alleles, typically following Mendel's laws of inheritance.
