It seems you might be referring to "Silver Ficus" plants. While "Silver Ficus" isn't an official name for any well-known species in the Ficus genus, it's possible that you are referring to a ficus plant variety with silvery or variegated foliage. Some ficus plants exhibit unique leaf patterns that include silvery or lighter-colored variegation. Here are a few types of ficus that might fit your description:

1. Ficus Elastica ‘Tineke’ (Variegated Rubber Plant):

• This popular ficus variety has large leaves with green centers, creamy white or silvery margins, and sometimes a hint of pink or red.
• The light-colored margins of the leaves can give a silvery appearance.
• It prefers bright, indirect light and moderate watering.
• It's an easy-to-care-for plant and is commonly grown indoors.

2. Ficus Benjamina ‘Silver Cloud’ (Variegated Weeping Fig):

• A variety of Ficus Benjamina known for its small, delicate leaves with a mix of green and creamy white or silvery patches.
• The variegated foliage gives the plant a light, airy appearance.
• It thrives in bright, indirect light but can tolerate lower light conditions.
• Needs well-draining soil and regular watering, allowing the soil to dry out slightly between waterings.

3. Ficus Triangularis ‘Variegata’ (Variegated Triangle Fig):

• Known for its distinctive triangular leaves with green centers and creamy white or silvery edges.
• This variegated variety is particularly attractive and makes a great decorative houseplant.
• It requires bright, indirect light and should be watered moderately.

4. Ficus Microcarpa ‘Green Island Variegata’ (Variegated Green Island Ficus):

• A compact ficus with glossy leaves that have silvery or creamy variegation.
• Often used for bonsai, it has a dense growth habit and can be pruned to maintain shape.
• Grows best in bright, indirect light and well-draining soil, and requires regular watering.

Care Tips for Variegated Ficus Plants:

• Light: Variegated ficus plants generally prefer bright, indirect light to maintain their leaf color and variegation. Too little light can cause the variegation to fade.
• Watering: Allow the top inch of soil to dry out between waterings. Overwatering can lead to root rot, while underwatering can cause leaf drop.
• Humidity: Ficus plants typically prefer higher humidity levels. If the air is too dry, especially in winter, consider misting the leaves or using a humidity tray.
• Temperature: Keep the plant in a warm environment, ideally between 60-75°F (16-24°C), and avoid cold drafts or sudden temperature changes.
• Fertilization: Feed the plant with a balanced fertilizer every 4-6 weeks during the growing season to support healthy growth.
