Thaumatophyllum bipinnatifidum, commonly known as the Lacy Tree Philodendron or Selloum, is a large, evergreen plant characterized by its deeply lobed, glossy green leaves. Despite its common name, it is not a true philodendron. It exhibits a shrub-like growth habit, developing a thick, trunk-like stem as it matures. While it can reach impressive sizes outdoors, indoor specimens remain more manageable. It's popular for its bold, tropical appearance and relatively easy care, making it a statement piece in homes and offices.

Syringa vulgaris

Syringa vulgaris, the common lilac, is a deciduous shrub or small tree, typically growing to 2-7 meters (6-23 feet) tall. It is widely cultivated for its fragrant, showy flowers that bloom in spring. The flowers are typically lilac to mauve in color, but white, pink, and purple varieties exist. Lilacs are primarily outdoor plants, valued for their beauty and fragrance in gardens and landscapes. They are not well-suited for indoor cultivation due to their high light requirements and need for a dormant period.

💡 Pro Tips For Comparing These Plants

Lacy Tree Philodendron Care Tips

Lacy Tree Philodendrons are relatively easy to care for indoors, provided they receive adequate light and are not overwatered. They require well-draining soil and occasional fertilization. Regular cleaning of the leaves will keep them healthy and attractive. They can become large, so provide ample space.

  • Provide bright, indirect light for optimal growth.
  • Allow the top 2-3 inches of soil to dry out before watering.
  • Fertilize regularly during the growing season.
  • Wipe the leaves with a damp cloth to remove dust and improve photosynthesis.
  • Provide a support structure, such as a moss pole, for the plant to climb if desired.
❄️ Winter: Reduce watering frequency as the plant's growth slows down. Ensure the plant is not exposed to cold drafts. Provide supplemental light if needed.
☀️ Summer: Water more frequently during the warmer months as the plant actively grows. Protect the plant from intense, direct sunlight to prevent leaf burn. Increase humidity if possible.

Lilac Care Tips

Lilacs are primarily outdoor plants and are very difficult to grow indoors. They require full sun, a dormant period, and proper pruning to thrive. Indoor cultivation is not recommended due to the difficulty in meeting these needs.

  • Prune immediately after flowering to encourage new growth and more blooms next year.
  • Ensure good air circulation to prevent powdery mildew.
  • Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
  • Fertilize in early spring with a balanced fertilizer.
  • Protect from strong winds and extreme cold.
❄️ Winter: Provide protection from extreme cold, especially for young plants. Mulch around the base of the plant to insulate the roots. Avoid pruning in late fall or winter.
☀️ Summer: Water regularly during dry periods. Mulch around the base of the plant to retain moisture. Monitor for pests and diseases.

❓ Frequently Asked Questions — Comparing These Plants

Lacy Tree Philodendron

What are the light requirements for Lacy Tree Philodendron?

Lacy Tree Philodendrons require bright, indirect light to thrive. Direct sunlight can scorch their leaves, causing unsightly burns. An east-facing window is often ideal, providing gentle morning sun. A north-facing window can also work, but the plant may grow slower. If placed near a south or west-facing window, use a sheer curtain to filter the intense light. Insufficient light can lead to leggy growth and smaller, less-defined leaves. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the leaves for signs of light stress, such as yellowing or browning.

How do I care for Lacy Tree Philodendron?

Lacy Tree Philodendrons thrive in bright, indirect light; avoid direct sunlight to prevent leaf burn. Water when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain humidity levels around 60-70% by misting regularly or using a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 1-2 years, or when the plant becomes root-bound, using a well-draining potting mix. Provide support, such as a moss pole, as the plant matures and its aerial roots develop. Regularly wipe the leaves to remove dust and pests. Keep temperatures between 65-80°F (18-27°C).

How do I propagate Lacy Tree Philodendron?

Lacy Tree Philodendrons can be easily propagated through stem cuttings, division, or air layering. For stem cuttings, take a cutting with at least one node and place it in water or directly into moist potting mix. Keep the cutting in a warm, humid environment until roots develop. For division, carefully separate the root ball into smaller sections and repot each section into its own container. Air layering involves wrapping a node with moist sphagnum moss and covering it with plastic wrap until roots form, then cutting below the roots and potting the new plant.

Lilac

What are the light requirements for Lilac?

Lilacs demand ample sunlight to produce abundant blooms. Ideally, they need at least six to eight hours of direct sunlight each day. Insufficient sunlight can lead to weak growth, sparse flowering, and increased susceptibility to diseases. When planting, choose a location that receives full sun exposure throughout the day. If your lilac is in a partially shaded area, consider transplanting it to a sunnier spot. Morning sun is particularly beneficial as it helps dry the leaves and reduces the risk of fungal infections. If you live in a region with intense afternoon sun, some light afternoon shade may be beneficial, especially for younger plants.

How do I care for Lilac?

Lilacs thrive in full sun, requiring at least six hours of direct sunlight daily. They prefer well-draining soil with a slightly acidic to neutral pH. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Fertilize in early spring with a balanced fertilizer formulated for flowering shrubs. Prune immediately after flowering to remove spent blooms and encourage new growth for the following year. Provide good air circulation to prevent fungal diseases. Mulch around the base of the plant to retain moisture and suppress weeds. Protect young plants from harsh winter winds. Monitor for pests like aphids and scale, and treat promptly if necessary. Regularly check the soil for nutrient deficiencies and adjust fertilization as needed. With proper care, your lilac will reward you with years of beautiful blooms.

How do I propagate Lilac?

Lilacs can be propagated through several methods. Division is best done in early spring or fall. Carefully dig up the plant and separate the root ball into sections, ensuring each section has healthy roots and stems. Stem cuttings should be taken in late spring or early summer. Select healthy, non-flowering stems and cut them into 4-6 inch lengths. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist until they root. Keiki propagation is not applicable to Lilacs, as they do not naturally produce keikis.
