Globe Thistle
Echinops bannaticus
Echinops bannaticus, or Blue Globe Thistle, is a striking perennial known for its spherical, steel-blue flower heads that sit atop tall, erect stems. Typically growing to a height of 3-5 feet, it features deeply lobed, thistle-like foliage that is grayish-green. This plant is primarily grown outdoors as a garden ornamental, attracting pollinators like bees and butterflies. While its architectural form and unique flower color make it desirable, it is not naturally suited for indoor environments due to its high light requirements and size.
Maltese Cross
Lychnis chalcedonica
Lychnis chalcedonica, commonly known as Maltese Cross, is a herbaceous perennial prized for its vibrant, scarlet-red, cross-shaped flower clusters. It typically grows to a height of 60-90 cm (2-3 feet). The plant features upright stems with lance-shaped, slightly hairy leaves. It is primarily an outdoor plant, thriving in sunny gardens and borders. People grow it for its eye-catching flowers that attract pollinators like butterflies and hummingbirds, adding a splash of color to summer gardens. It is not ideally suited for indoor cultivation due to its high light requirements and need for a dormancy period.
