formosan lily

Lilium formosanum

Formosan lily (Lilium formosanum) is a bright and beautiful flower native to Taiwan. It has deep green narrow leaves and tall stalks with downward-facing bell-shaped blooms that come in shades of pink, orange or yellow. The flowers are raised above the foliage, which can add 2 to 3 feet of height to any garden. The plant is not overly demanding and will grow in full or partial shade. During the summer months, it will need lots of water and may need to be staked to provide support. Formosan lilies are low maintenance, deer and drought resistant, making them an ideal choice for a colourful and long-lasting border.

watering

Formosan lilies should be watered regularly, approximately once a week, making sure that the soil is consistently moist but not soggy. For optimal health, the plant should be provided with 1-2 inches of water each time. It is important to note that this lily does not do well in overly wet soil, so it is very important not to overwater. In addition, as the plant matures, it may need to be watered more frequently during warm or dry seasons.

sunlight

Formosan lily requires full sunlight for at least 6-7 hours of the day for optimal growth conditions. To ensure that this species of lily is thriving, the source of sunlight should be direct rather than filtered from a nearby window. It is recommended to place this plant in a spot in your garden where it will get the most sunlight. During the summer months, the lily can benefit from the sun during the entire day, but during winter, it should be provided with at least 6 hours of direct sunlight per day.

pruning

Formosan lilies should be pruned in late autumn or early winter, when the leaves have died back and not yet begun growing again. This species should be lightly pruned, taking no more than approximately 10 to 15% of the foliage at any given time. This will help maintain the size and shape of the plant while also keeping it healthy and productive. In addition, dead or diseased stems or leaves should be removed when needed.
