Lotus berthelotii, commonly known as Parrot's Beak, is a trailing perennial plant characterized by its silvery-gray, needle-like foliage and striking, claw-shaped red or orange flowers. Native to the Canary Islands, it is often grown as an ornamental plant in hanging baskets or as a ground cover. Its unique appearance and drought tolerance make it a popular choice for rock gardens and coastal landscapes. It is primarily an outdoor plant, thriving in full sun and well-drained soil. While it can be brought indoors, it requires very bright light and careful watering to prevent root rot.

Sea Holly

Sea Holly

Eryngium spp.

Sea Holly (Eryngium spp.) is a genus of perennial flowering plants known for their thistle-like appearance and metallic blue or silver foliage. Typically found in coastal and grassland habitats, they feature spiky bracts surrounding a central cone-shaped flower head. These plants are grown for their unique architectural form, drought tolerance, and long-lasting cut flowers. They are primarily outdoor plants and can be challenging to grow indoors due to their high light requirements and need for well-draining soil. Their striking appearance makes them a popular choice for xeriscaping and adding textural interest to gardens.

❓ Frequently Asked Questions — Comparing These Plants

Lotus Vine

What are the light requirements for Lotus Vine?

Lotus Vine thrives in bright, indirect light. Direct sunlight can scorch its delicate leaves, so avoid placing it in a south-facing window without some form of shading. An east- or west-facing window is ideal, providing ample light without the harsh intensity. If you notice the leaves fading or the plant becoming leggy (long stems with sparse foliage), it’s likely not receiving enough light. Consider supplementing with a grow light, especially during the darker months of the year. Rotate the plant regularly to ensure even light exposure on all sides.

How do I care for Lotus Vine?

Lotus Vine requires bright, indirect light. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain moderate humidity levels. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to encourage bushier growth and remove any dead or yellowing foliage. Provide support if you want it to climb, or allow it to trail freely. Repot every 1-2 years into a slightly larger pot with well-draining potting mix. Protect from frost and cold drafts. Monitor for pests such as aphids and spider mites.

How do I propagate Lotus Vine?

Lotus Vine can be propagated easily through stem cuttings or layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant it in moist, well-draining potting mix. Cover with a plastic bag to create a humid environment and place in bright, indirect light. Roots should develop within a few weeks. For layering, bend a long stem down to the soil surface and bury a section of it, leaving the tip exposed. Once roots develop along the buried section, sever it from the mother plant and pot it up separately.

Sea Holly

What are the light requirements for Sea Holly?

Sea Holly demands abundant sunlight to flourish. Aim for a minimum of six to eight hours of direct sunlight each day. Insufficient light can result in leggy growth, reduced flowering, and duller foliage. When planting, choose a location that receives full sun exposure throughout the day. If growing in containers, position them in the sunniest spot possible, such as a south-facing patio or balcony. In regions with intense summer heat, provide some afternoon shade to prevent scorching of the foliage. Rotate potted plants regularly to ensure even light exposure on all sides, promoting balanced growth and abundant blooms.

How do I care for Sea Holly?

Sea Holly thrives in full sun and well-drained soil. Provide at least 6-8 hours of direct sunlight daily for optimal growth and flowering. Water deeply but infrequently, allowing the soil to dry out between waterings to prevent root rot. Fertilize sparingly with a low-nitrogen, high-phosphorus fertilizer in spring to encourage blooming. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers. Deadhead spent blooms to promote continued flowering. Sea Holly is relatively drought-tolerant once established, making it a low-maintenance plant. Ensure good air circulation around the plant to prevent fungal diseases. Protect from excessive winter moisture in colder climates. Amend heavy clay soils with sand or gravel to improve drainage.

How do I propagate Sea Holly?

Sea Holly can be propagated through division, root cuttings, or seed. For division, carefully dig up established clumps in spring or fall and separate the roots into individual plants, ensuring each has healthy roots and foliage. Replant immediately in well-draining soil. Root cuttings can be taken in late winter or early spring. Dig up the plant and take 2-3 inch root cuttings, planting them horizontally in a sandy soil mix. Keep moist until new growth appears. Seeds can be sown in spring or fall, but may require stratification (cold treatment) for optimal germination. Sow seeds in a well-draining seed-starting mix and keep moist until germination occurs.
