African marigolds are big bold flowers that are flamboyant and colorful. They are a great addition to a flowerbed, border or a large container.
Most African marigolds are cream, orange, or yellow and can grow up to 3 feet tall.
They produce huge 3 inch puffball blooms while dwarf varieties get just 1 foot tall.
The mounded dark green foliage is always clean, fresh and tidy.
They are best grown in a warm, sunny spot with moist, well drained soil throughout the summer. (source)
So can guinea pigs eat African marigolds?
Unfortunately, they are not a good food for guinea pigs to eat and should be avoided as a food for them.
