Lycopodium clavatum
Lycopodium clavatum, commonly known as Club Moss, is a creeping, evergreen perennial plant that resembles a moss but is actually a vascular plant. It spreads via rhizomes, forming extensive mats in acidic, well-drained soils. The plant features trailing stems with small, scale-like leaves arranged spirally around the stem. It produces erect strobili (spore-bearing cones) at the tips of its branches, giving it a distinctive club-like appearance. While historically used medicinally and for other purposes, it's primarily an outdoor plant. People may attempt to grow it indoors for its unique texture and appearance, but success is limited.
Eryngium
Eryngium spp.
Eryngium, commonly known as Sea Holly, is a genus of annuals and perennials characterized by their thistle-like appearance and striking metallic blue or silver coloration. Most species are native to coastal or grassland habitats. They feature spiny bracts surrounding cone-shaped flower heads composed of numerous tiny flowers. The foliage is often deeply lobed or divided. Eryngium is primarily grown outdoors for its architectural form, drought tolerance, and long-lasting cut flowers. While some people attempt to grow them indoors, they rarely thrive due to the high light requirements.
