Asters are primarily late-summer and fall-blooming perennials, known for their daisy-like flowers in various shades of purple, pink, blue, and white. They are herbaceous plants, meaning they die back to the ground in winter and re-emerge in spring. Asters are popular garden plants, providing a burst of color when many other flowers are fading. They attract pollinators like bees and butterflies. While some species are more compact, others can be quite tall and spreading. Asters are generally outdoor plants and struggle indoors due to high light requirements and dormancy needs.

Hens and Chicks

Sempervivum tectorum

Sempervivum tectorum, commonly known as Hens and Chicks, is a succulent perennial forming a rosette of fleshy, pointed leaves. The 'hen' is the main, larger rosette, which produces numerous smaller rosettes ('chicks') around its base, hence the name. Primarily an outdoor plant, it thrives in well-draining soil and full sun. People grow it for its unique appearance, drought tolerance, and ease of propagation. It's often used in rock gardens, green roofs, and container arrangements. While it can be attempted indoors, providing sufficient light is challenging.
