Aesculus hippocastanum aka Common Horse Chestnut

Aulus hippocastanum, commonly known as horse chestnut or conker tree, is a large, deciduous tree belonging to the Sapindaceae family. It is native to Europe and is widely cultivated in streets and parks throughout temperate regions of the world. The tree can grow up to 25 meters high with a broad and spreading crown. Its buds are large, ovate pointed, green-brown, and often sticky, with noticeably large leaf scars underneath. The bark of the trunk is first smooth and later slightly cracked, with a color ranging from brown to gray-green. The chestnut leaf is fingered with seven cut leaves and up to 20 cm long. The inflorescences are 20-30 cm high and are erected like a flower, with colors ranging from white to yellow-red. The tree flowers in May. European Horse-Chestnut is also a rare houseplant that belongs to the same Aesculus genus. It needs regular watering to thrive and prefers well-draining soil. It does best in long-lasting, direct light and should be less than 1 foot from a window. Repotting each time it doubles in size is recommended, and added fertilizers are not necessary. It is extremely dangerous if consumed. It is important to note that horse chestnut should not be confused with the Spanish chestnut, Castanea sativa, which is a tree in another family.
