Pelargonium and tomato plant:

2 separate plants in different locations but same situation

The pelargonium is approximately 7 years old from a cutting. One branch and the same branch each year produces distintly different flowers. Same kind of flower, same size and shape flower but some clusters are always predominantly white like the rest of the plant and periodically a full cluster is always uniformly magenta.

The tomato plant is producing fruit normally with normal leaf growth. One stem produces yellow/orange ripe fruit. The rest of the plant produces red fruit. This plant was grown from seed, unknown parentage.

Any thoughts?

Thank you,

Dave
