Autumn Crocus
Colchicum autumnale
Colchicum autumnale, commonly known as Autumn Crocus, is a perennial flowering plant that blooms in the autumn. It produces goblet-shaped flowers in shades of pink, purple, or white, arising directly from the ground without leaves. The leaves appear in the spring, after the flowers have faded. It is primarily an outdoor plant, grown for its late-season blooms that add color to gardens when many other plants are dormant. People grow it for its unique flowering time and attractive appearance.
Perilla
Perilla frutescens
Perilla frutescens, commonly known as Shiso, is an annual herb typically grown outdoors for its aromatic leaves, which are used in East Asian cuisine. It grows to about 0.5-1 meter tall with a bushy habit. The leaves come in various colors, including green, purple, and variegated forms. While it can be grown indoors, it requires very bright light and consistent care to thrive. People grow it for its culinary uses, ornamental value, and purported medicinal properties. It is considered an invasive species in some regions.

❓ Frequently Asked Questions — Comparing These Plants
Autumn Crocus
What are the light requirements for Autumn Crocus?
Autumn Crocus needs at least six hours of sunlight daily for optimal blooming. While they can tolerate partial shade, too little light can result in fewer flowers and leggy growth. In warmer climates, afternoon shade can protect the flowers from scorching. When planting, choose a location that receives morning sun and afternoon shade if possible. For indoor growing, place the pots near a sunny window that receives direct sunlight for several hours each day. Rotate the pots regularly to ensure even light exposure on all sides of the plant. Insufficient light can lead to weak stems and a lack of blooms. Pay close attention to the plant’s growth and adjust its placement accordingly.
How do I care for Autumn Crocus?
Autumn Crocus thrives in well-drained soil and prefers full sun to partial shade. Plant the bulbs in late summer, about 4-6 inches deep and 4-6 inches apart. Water thoroughly after planting. Once established, they require minimal watering, especially during dormancy. Fertilize lightly in spring with a balanced fertilizer to encourage healthy growth and abundant blooms. Protect from slugs and snails, which can damage the foliage and flowers. Allow the foliage to die back naturally after blooming to replenish the bulb’s energy stores. Avoid mowing the foliage until it has completely withered. In colder climates, a layer of mulch can help protect the bulbs during winter. Regularly check for signs of pests and diseases.
How do I propagate Autumn Crocus?
Autumn Crocus are primarily propagated through bulb division. This is best done in the summer when the plants are dormant. Carefully dig up the bulbs and separate the smaller bulblets from the main bulb. Replant the bulblets in well-draining soil, about 4-6 inches deep and 4-6 inches apart. Water thoroughly after planting. Alternatively, some species can be propagated by seed, but this is a slower process and may take several years to produce flowering plants. Stem cuttings and keiki propagation are not applicable for Autumn Crocus, as they are bulbous plants. Ensure the newly planted bulbs receive adequate sunlight and moisture to establish healthy root systems. Patience is key, as it may take a season or two for the new bulbs to mature and bloom.
Perilla
What are the light requirements for Perilla?
Perilla thrives in bright, indirect light. Insufficient light can lead to leggy growth and reduced blooming. Avoid direct sunlight, especially during the hottest part of the day, as it can scorch the leaves. An east-facing window is ideal, providing gentle morning sun. A west-facing window can also work, but be sure to provide some shade during the afternoon.
How do I care for Perilla?
Perilla requires bright, indirect light for optimal growth and blooming. Direct sunlight can scorch the leaves. Water thoroughly when the top inch of soil feels dry. Ensure good drainage to prevent root rot. Fertilize regularly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to encourage bushier growth and remove spent flowers.
How do I propagate Perilla?
Perilla can be propagated through stem cuttings. Take a 4-6 inch stem cutting from a healthy plant. Remove the lower leaves. Dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix. Keep the soil moist but not soggy. Place the cutting in a warm, bright location. Roots should develop in 2-4 weeks.
