Sunflowers are called girasoles in spanish. Their yellow and black faces can be seen peeking over the tops cornstalks and fences throughout the garden. Bringing joy to the gardener and bees to the plants, sunflowers are a must have in gardens around the world. In many indigenous American gardens, sunflowers are planted along the northern edge of the parcel. This is done so they don’t shade out the garden. In the northern hemisphere, the suns rays come from the south making it the sunniest side of the garden. any tall plants or structures on the southern edge of the garden will shade out the garden.
