How To Care For Starfish Iris

In terms of Size and Growth

Despite the fact that it is not a real iris or lily, it is easy to understand why it was given those names. If plants are not pruned on a regular basis, they may produce thick clusters that are difficult to remove, resulting in corms that are tough to remove. Each plant grows to be between 12 and 18 inches tall, and the plant grows at a somewhat modest rate overall.

The gorgeous sword-shaped leaves have a lovely blue-green hue to them. It may emerge in the spring and autumn depending on your area and the attitude of the plant, but it may die back in the summer and winter depending on your location and the mood of the plant. It is possible that it has just one growth season in a given year.

Floral and Scent Elements

In this plant’s case, the most astonishing part of its behavior is also one of the most hardest to comprehend. People may be able to tell when the plant is blooming based on where it is, as well as how different it is from other plants.

The Starfish Iris blooms from late winter to mid-summer, depending on the climate. Additionally, according to some stories, they bloom throughout the autumn. These velvety-edged, frilly-edged flowers are often available in yellow (with occasional exceptions in white, green, and brown), and they may have patches of black, brown, or purple on their petals.

Each bloom is roughly 1 1/2 inches in diameter and has three long petals and three shorter petals on each side. These flowers may arise swiftly from a number of stem branches, with two to three branches per corm, and can last for many days.

Each individual flower only lasts for a day, despite the fact that the entire bloom length might last for over a year. Before purchasing plants from a grower, inquire about certain odors.

A frequent aroma in starfish iris is sweet vanilla, which draws butterflies and hummingbirds to the blooms. Others have odors that are more like the stench of decaying flesh, and these are intended to attract other types of pollinating insects to their colonies.

Lighting and Temperature Considerations

Despite the fact that this Starfish Iris prefers full sun, it may be able to survive a midday shadow under more severe weather conditions. USDA zones 3 through 11 are suitable for growing it outdoors. In zones 3 through 8, you will need to bring the corms indoors for the winter. Zones 9 through 11 may be retained on the ground if necessary.

Despite the fact that they are not frost resistant, they can grow in temperatures ranging from 40 to 75 degrees preferable if evening temperatures are about 65 degrees Fahrenheit. It will fall dormant if temperatures rise above 75 degrees Fahrenheit (24 degrees Celsius).

Watering and Feeding the Starfish Iris

This is why the soak-and-dry method is effective for these plants. Here are some suggestions that may be of assistance.

Using a gentle pouring motion, water the soil when it feels dry, 1 inch deep, until the soil can no longer absorb the water at the same rate you’re pouring it.

The moment wetness can be seen in the drainage holes of container plants, it’s time to put the plants down. If the plant goes into dormancy, limit the amount of water it receives and wait until fall. Before storing the dirt, it must be totally dry.

It works really well when used with a balanced liquid fertilizer for houseplants that has been lowered to half its original concentration. It’s important to know how your plant grows so that you can change its feeding schedule in the right way.

When new growth appears, the first feed should be given roughly 2 to 3 weeks after the development of new growth.

Whether the plant continues to develop throughout summer (at which time you will need to feed it again 2 to 3 months after the initial feeding) or whether it is dormant in summer and active in autumn will decide how many further feedings you will need (at which point, provide once as you did in spring).

Transplanting and Soil Improvement

This consistency is best suited for loamy to sandy soils that drain fast. To attain this consistency, you may amend your garden soil with coconut coir or perlite. 1 to 2 pieces of African violet mixed with coarse sand or perlite is adequate for potted specimens of this plant.

These plants should be split every three to five years. Otherwise, they will become too crowded and their ability to produce blooms will be severely limited, so they should be split every few years.
