About Online Flower Garden & Dino

I am a flower enthusiast and a gardener at heart. Ever since childhood I loved reading about plants and started gardening at an early age. First by helping my father in the garden and later managing a large garden myself in my teen years. I planted and cared for a large number of plants, flowers, and trees both outdoors and in a greenhouse. To this day I enjoy visiting gardens and parks and learning about new and old specimens and varieties of plants.
