Hollyhock Mallow
Malva alcea
Malva alcea, commonly known as Hollyhock Mallow, is a herbaceous perennial prized for its charming, hollyhock-like flowers. Typically grown outdoors, it features upright stems reaching up to 1.5 meters tall, adorned with deeply lobed, rounded leaves. The plant produces an abundance of saucer-shaped, pink to rose-purple flowers throughout the summer. It is a popular choice for cottage gardens, borders, and wildflower meadows, attracting pollinators like bees and butterflies. While occasionally attempted indoors, it struggles due to high light requirements and space limitations.

Pink Muhly Grass is a warm-season perennial grass prized for its spectacular floral display in the fall. It forms an upright, rounded clump of fine-textured, green foliage. In autumn, it produces airy plumes of pink to rose-colored flowers that create a cloud-like effect. It is primarily an outdoor ornamental grass, grown for its visual appeal in gardens and landscapes. It is not naturally suited for indoor environments due to its high light requirements and size.
