Candytuft

Iberis sempervirens

Iberis sempervirens, commonly known as Candytuft, is a low-growing, spreading evergreen perennial. It forms a dense mat of dark green, linear leaves and produces masses of small, white flowers in spring, creating a snow-like effect. While primarily an outdoor plant valued for its ground cover and spring blooms in rock gardens and borders, it is not ideally suited for indoor cultivation due to its high light requirements and need for cooler temperatures to thrive. People grow it for its early spring blooms and drought tolerance.

Speedwell

Veronica spp.

Speedwell encompasses a diverse genus of flowering plants, primarily herbaceous perennials, though some are annuals or shrubs. They exhibit a range of growth habits, from creeping groundcovers to upright forms. The flowers are typically small and blue, but can also be pink, white, or purple, arranged in spikes or racemes. Speedwell is primarily grown outdoors in gardens and meadows for its attractive flowers and ability to attract pollinators. While some species are relatively adaptable, they generally require specific outdoor conditions that are difficult to replicate indoors.

Speedwell

What are the light requirements for Speedwell?

Speedwell flourishes in full sun, requiring at least six hours of direct sunlight each day for optimal growth and abundant blooming. While it can tolerate some partial shade, especially in hotter climates, insufficient light can lead to leggy growth and reduced flowering. When planting Speedwell, choose a location that receives ample sunlight throughout the day. If growing indoors, place the plant near a sunny window, ideally facing south or east. Rotate the plant regularly to ensure even light exposure on all sides. In areas with intense afternoon sun, providing some light shade during the hottest part of the day can prevent leaf scorch.
