This grower is sure of this plant identification.
English oak seedlings, self-seeded from the 200 year old oak tree in my garden, removed from flower beds and planted in pots. Varying sizes and pot types/colours.
Quercus genus (Oak). There are about 600 or so evergreen, semi-evergreen and deciduous species in this genus. They are usually very long lived, and some species have been used for centuries for their hardwood timber. The leaves are lobed and leathery; some species are thin and lustrous. The female flowers are small and insignificant and greenish. The male flowers appear as yellow catkins in spring.
They are fully to frost hardy, and grow in sun or semi-shade in deep, well drained soil.
Grown for their habit, foliage and, in some deciduous species their autumn colour. Suitable for coastal conditions. Attracts butterflies and a variety of wildlife.
