Lupinus spp.

Lupinus is a genus of flowering plants characterized by their distinctive palmate leaves and tall, showy flower spikes. These plants are typically herbaceous perennials or annuals, growing from 0.3 to 1.5 meters tall. The flowers come in a wide range of colors, including blue, purple, pink, white, and yellow. Lupins are primarily grown outdoors for their ornamental value in gardens and meadows, attracting pollinators like bees and butterflies. They are not typically grown indoors due to their high light requirements and size.

Monkey Flower

Mimulus aurantiacus

Mimulus aurantiacus, commonly known as Sticky Monkey-flower, is a perennial shrub native to the California chaparral. It typically grows to 1-5 feet tall and wide, featuring narrow, sticky leaves. The plant is named for its bright orange, tubular flowers that resemble a monkey's face. It thrives in dry, sunny conditions and is well-adapted to drought. While primarily an outdoor plant, it is grown for its vibrant flowers and ability to attract pollinators like hummingbirds and butterflies. Indoor cultivation is challenging due to its high light requirements and need for well-draining soil.

💡 Pro Tips For Comparing These Plants

Lupin Care Tips

Lupins are primarily outdoor plants and are challenging to grow indoors due to their high light requirements and size. They need full sun, well-draining soil, and careful watering. Indoor cultivation is generally not recommended.

  • Provide support for tall flower spikes to prevent them from bending or breaking.
  • Deadhead spent flowers regularly to encourage continuous blooming.
  • Ensure good drainage to prevent root rot.
  • Protect from strong winds that can damage the flower spikes.
  • Monitor for pests and diseases and treat promptly.
❄️ Winter: In colder climates, protect lupins from frost by mulching around the base of the plant. Cut back foliage after flowering and allow the plant to enter dormancy.
☀️ Summer: Water regularly during dry periods. Deadhead spent flowers to encourage further blooming. Provide support for tall flower spikes to prevent them from bending or breaking.

Monkey Flower Care Tips

Sticky Monkey-flower is primarily an outdoor plant that requires full sun and well-draining soil. Indoor cultivation is challenging due to its high light needs. It is drought-tolerant once established but benefits from occasional watering during dry periods. Pruning after flowering encourages bushier growth. Indoor growing is difficult to achieve.

  • Provide full sun for optimal flowering.
  • Ensure well-draining soil to prevent root rot.
  • Water deeply but infrequently, allowing the soil to dry out between waterings.
  • Prune lightly after flowering to encourage bushier growth.
  • Avoid over-fertilizing, as this can lead to leggy growth.
❄️ Winter: In colder climates, protect from frost with mulch or move container plants to a sheltered location. Reduce watering during the dormant season.
☀️ Summer: Provide adequate water during dry spells. Deadhead spent flowers to encourage continued blooming. Protect from intense afternoon sun in extremely hot climates.

❓ Frequently Asked Questions — Comparing These Plants

Lupin

What are the light requirements for Lupin?

Lupins require at least six to eight hours of direct sunlight per day to thrive and produce abundant blooms. Insufficient light can result in leggy growth, fewer flowers, and paler foliage. Choose a location in your garden that receives full sun throughout the day. If you live in a hotter climate, provide some afternoon shade to protect the plants from scorching. When starting lupins indoors, use grow lights to supplement natural light, especially during the shorter days of winter. Rotate the plants regularly to ensure even light exposure on all sides. A south-facing location is ideal, but east or west-facing spots can also work if they receive enough sunlight.

How do I care for Lupin?

Lupins thrive in well-drained, slightly acidic soil. Full sun is essential for optimal flowering, but they can tolerate partial shade, especially in hotter climates. Water regularly, especially during dry spells, but avoid overwatering to prevent root rot. Fertilize in early spring with a balanced fertilizer or a fertilizer formulated for flowering plants to encourage abundant blooms. Deadhead spent flower spikes to promote further flowering and prevent self-seeding. Provide support for tall varieties to prevent them from flopping over. Protect from slugs and snails, which can damage young plants. Prune back after flowering to encourage a bushier habit. Monitor for pests like aphids and treat as needed. Mulch around the base of the plant to retain moisture and suppress weeds. Ensure good air circulation to prevent fungal diseases.

How do I propagate Lupin?

Lupins can be propagated by seed, division, or stem cuttings.

Monkey Flower

What are the light requirements for Monkey Flower?

Monkey Flowers require bright, indirect light for optimal growth and blooming. Direct sunlight can scorch the leaves, especially during the hottest part of the day. An east-facing window is ideal, providing gentle morning sun. A west-facing window can work, but be sure to provide shade during the afternoon. If growing indoors, supplement with grow lights if natural light is insufficient. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides. If the leaves start to look pale or yellowish, it may be a sign of too much light.

How do I care for Monkey Flower?

Monkey Flowers thrive in bright, indirect light. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Fertilize regularly during the blooming season with a balanced liquid fertilizer, diluted to half strength, every two to four weeks. Maintain moderate humidity levels, around 40-60%. Prune spent flowers to encourage new blooms. Repot in spring if the plant becomes root-bound, using a well-draining potting mix. Monitor for pests like aphids and spider mites, and treat promptly with insecticidal soap. Provide good air circulation to prevent fungal diseases. In winter, reduce watering and hold off on fertilizer.

How do I propagate Monkey Flower?

Monkey Flowers can be propagated through division, stem cuttings, and seed.
