Chrysanthemum × morifolium

Chrysanthemum × morifolium, commonly known as mums, are popular flowering plants cultivated for their vibrant and diverse flower colors and forms. They are herbaceous perennials, typically grown as annuals in many climates due to their sensitivity to frost. Mums are characterized by their bushy growth habit and composite flower heads, which come in various shapes like daisy-like, pompon, and spider. While primarily outdoor plants, they are often brought indoors for short periods to enjoy their blooms, but they require specific conditions to thrive indoors long-term. People grow them for ornamental purposes, adding color to gardens and homes, and for cut flowers.

Princess Tree

Paulownia tomentosa

Paulownia tomentosa, the Princess Tree, is a deciduous tree known for its rapid growth and large, heart-shaped leaves. It can reach heights of 30-60 feet. In spring, it produces fragrant, pale purple flowers in panicles before the leaves emerge. These are followed by persistent seed capsules. While admired for its ornamental value, it's considered invasive in many regions due to its prolific seed production and ability to resprout from roots. It is primarily an outdoor tree and not suitable for indoor cultivation.

  • Provide excellent drainage to prevent root rot.
  • Water deeply but infrequently, allowing the soil to dry slightly between waterings.
  • Fertilize regularly during the growing season with a balanced fertilizer.
  • Monitor for pests and diseases and treat promptly.
❄️ Winter: Reduce watering in winter. If overwintering outdoors, mulch heavily. If overwintering indoors, keep in a cool, bright location.
☀️ Summer: Provide regular watering and fertilization. Protect from intense afternoon sun in hot climates. Pinch back stems regularly until mid-summer.

❓ Frequently Asked Questions — Comparing These Plants

Mum

What are the light requirements for Mum?

Mums thrive in bright, indirect light. They need at least 6 hours of sunlight per day to produce abundant blooms. An east- or west-facing window is ideal, providing ample light without the harshness of direct sunlight. Insufficient light can lead to leggy growth and reduced flowering.

How do I care for Mum?

To care for your Mum, provide bright, indirect light, ideally near an east- or west-facing window. Water thoroughly when the top inch of soil feels dry to the touch, ensuring good drainage to prevent root rot. Fertilize every two weeks during the growing season (spring and summer) with a balanced liquid fertilizer, reducing frequency in the fall.

How do I propagate Mum?

Mums can be propagated through division, stem cuttings, or occasionally from keiki.

Princess Tree

What are the light requirements for Princess Tree?

Princess Tree thrives in bright, indirect light. Insufficient light can lead to leggy growth and reduced leaf size. Place your Princess Tree near a sunny window, ideally facing east or west. If you only have a south-facing window, filter the light with a sheer curtain to prevent scorching. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is limited, consider supplementing with artificial grow lights to provide the necessary light intensity. Pale leaves or slow growth can indicate insufficient light.

How do I care for Princess Tree?

To successfully grow Princess Tree indoors, provide it with bright, indirect light; direct sunlight can scorch the leaves.
