How to Grow Perennial Senetti | Grow it All Year Round

Senetti is quickly becoming one of my favorite plants as it stays green all year round and has bright fluorescent flowers. Senetti will flower in winter, spring and fall and will have green leaves all year round. These plants will grow a full coverage of bright flowers which will last for 2-3 weeks.

These flowers can be trimmed back and you will get another coverage of flowers in 3 weeks time.

Senetti might be one of the showiest flowering plants in late winter with the option of hot pink, bright purple and even blues. I have recently added senetti to my garden and quickly discovered that there are some secrets to successfully growing this plant.

Senetti or Pericallis cruentus comes in a range of colors and I have gone for Magenta Delight. After planting two senetti in the same raised garden bed I quickly discovered the important of perfect positioning and what you must to prevent it drooping.

This article will explore how you can keep your senetti happy and green all year round and encourage a good coverage of flowers. Here are my top tips to successfully growing your perennial senetti.

How to grow a healthy perennial senetti

Here are my top tips to grow a healthy senetti that stays green, has a bright coverage of flowers and will look great in your garden.

Plant in afternoon shade

Senetti will thrive in afternoon shade so make sure you think about where you are going to put this plant. This was the first lesson I learnt with senetti as I planted one in a raise garden bed that got afternoon sun. After a few days it had drooped and struggled to settle in.

Senetti will flower brightly with morning sunlight but protection from the hot afternoon rays. Senetti will be available from nurseries in spring but if they go straight into afternoon sun it can be too warm and cause your senetti to droop.

I have since moved my senetti to a place in the front of my garden which gets afternoon shade. It is growing happily next to some clivias which famously love a shaded spot. This shows how much shade these plants actually need.

I have left one senetti in my raised garden bed as the end it is planted in is more protected.  This plant is not drooping and was happily transferred to this new space straight from the nursery.

Feed senetti regularly

Senetti will grow well if they are fed more regularly than your usual perennial flowering shrub. These plants grow large displays of flowers but to keep up this growth they will need plenty of food.

A general all purpose liquid plant food given every 4 weeks over spring and summer will help it stay green and will regrow flowers every 3-4 weeks. Producing a large amount of flowers takes a lot of energy and will quickly eat up the nutrients absorbed by the plant.

I also like to add a handful of pelleted chicken manure 2-3 times over spring to maintain the green leaves on the plant. This is a slower release fertilizer that will gently feed the senetti nitrogen alongside a range of other nutrients. It can also be added again in fall.

Keep senetti out of the wind

Wind can dry out the senetti quickly and damage the leaves and flowers.

Senetti will struggle to grow well if they are exposed to warm or dry wind. Windy weather can quickly dry a senetti plant and it will suffer and droop quickly. Senetti need protection so plant them near other shrubs or near a garden wall to protect them from the wind.

Senetti make the perfect partner to a mixed plant display that is made up of shade loving plants, citrus, other flowering shrubs or as a feature potted plant.

Keep senetti watered well

Senetti need regular water and will suffer if they experience long dry periods. Watch out for dry soil over summer and top them up with water if there is low rainfall in your area. I will check all of my plants regularly in summer and top up once or twice a week with water in the morning.

Water senetti near the roots in the morning to keep them happy on a warm day. You may see temporary drooping of their leaves but this will quickly pick up after the weather cools at night.

Understanding Perennial Senetti

Botanical Profile

Senetti is a hybrid of the Compositae and Asteraceae families and was formerly known as a cineraria hybrid. It is a colorful perennial plant that produces a large amount of flowers, which takes a lot of energy and nutrients. The plant has a bushy growth habit and can grow up to 2 feet tall and 1.5 feet wide. The leaves of Senetti are green and toothed, and the flowers come in shades of blue, pink, and purple.

Growth Habit

Site Selection and Soil Preparation

When it comes to growing perennial Senetti, selecting the right location and preparing the soil are crucial steps for ensuring a healthy and thriving plant. In this section, we will discuss the key factors you need to consider for site selection and soil preparation.

Choosing the Right Location

Choosing the right location for your Senetti plant is essential for its growth and development. Senetti plants require abundant sunshine, so it’s important to select a location that receives full sun for at least six hours a day. Additionally, Senetti plants prefer well-drained soil, so avoid planting them in areas that are prone to waterlogging.

Soil Requirements

Senetti plants prefer soil that is rich in organic matter and well-drained. Before planting, test your soil to determine its pH level. Senetti plants prefer a slightly acidic soil with a pH between 5.5 and 6.5. If your soil is too alkaline, you can lower the pH by adding organic matter such as peat moss, compost, or well-rotted manure.

Amending Soil

If your soil is poor in quality, amending it with organic matter can help improve its texture and fertility. Organic matter can also help improve soil drainage and water retention. Before planting, add a layer of organic matter such as compost or well-rotted manure to the soil and mix it in thoroughly. This will help improve soil structure and provide the necessary nutrients for your Senetti plant to thrive.

By carefully selecting the right location and preparing the soil, you can ensure your Senetti plant grows healthy and strong all year round.

Planting Senetti

When to Plant

Senetti plants can be planted at any time of the year, but it is best to plant them in the spring or fall. Planting in the spring will give the plant enough time to establish itself before the hot summer months, while planting in the fall will give the plant enough time to establish itself before the cold winter months.

Planting Guidelines

When planting Senetti, it is important to choose a location that receives full sun or partial shade. Senetti prefers slightly acidic soil with a pH of 5.6. You can achieve this by using a peat-based compost.

To plant Senetti, follow these simple guidelines:

  1. Prepare the soil by removing any weeds or debris and adding compost if necessary.
  2. Dig a hole that is twice the size of the root ball.
  3. Place the Senetti plant in the hole and backfill with soil.
  4. Water the plant thoroughly.

It is important not to plant Senetti too deeply. The top of the root ball should be level with the soil surface. Overwatering or underwatering can also cause problems, so make sure to water the plant only when the soil is dry to the touch.

By following these planting guidelines, you can ensure that your Senetti plant will thrive and produce beautiful blooms all year round.

Watering and Feeding

Watering Schedule

Senetti plants require regular watering to keep them healthy and thriving. It is recommended that you water your Senetti plants at least once every 7-10 days or whenever the top 2-3 inches of soil feels dry to the touch. During the warmer months when the plant is actively growing, you may need to increase watering frequency to every 7 days.

It is important to avoid overwatering your Senetti plants as this can lead to root rot and other fungal diseases. Make sure that the soil is well-draining and that the water is able to flow through the soil easily.

Fertilization Needs

Senetti plants are heavy feeders and require regular fertilization to keep them healthy and blooming all year round. You should feed your Senetti plants more regularly than your usual perennial flowering shrub to keep up their growth.

Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. You can also use a slow-release fertilizer to provide your Senetti plants with a constant supply of nutrients.

It is important to follow the manufacturer’s instructions when applying fertilizer to your Senetti plants. Over-fertilization can lead to burnt leaves and stunted growth. Apply fertilizer once every 2-3 weeks during the growing season, and reduce the frequency during the winter months when the plant is dormant.

By following a regular watering and fertilization schedule, you can ensure that your Senetti plants remain healthy and blooming all year round.

Pruning and Maintenance

Pruning Techniques

Pruning is an essential process in maintaining the health and beauty of your Senetti plant. Prune your Senetti regularly to keep it in good shape. Use clean and sharp pruning shears to make precise cuts without damaging the plant. Cut back the plant by one-third to one-half in the early spring to encourage new growth. Prune the plant again in late summer after the first flush of flowers to promote a second bloom.


Deadheading is the process of removing dead flowers from the plant to encourage new growth. Senetti will grow a huge coverage of flowers with even up to 100 individual flowers covering a small bush. Deadheading senetti after the first flush of flowers will refresh the bush and allow it replace the flowers. Trim the flowers down to the leaf level and water the plant well. Faded flowers should be cut to around 6 inches. And what’s more, the flower also has a unique ability to rebloom.

Winter Care

Senetti is a perennial plant that can survive the winter if you take proper care of it. In the fall, cut back the plant by one-third to one-half to prepare it for the winter. Cover the plant with a layer of mulch to protect it from the cold. Water the plant well before the first frost to help it survive the winter. In the spring, remove the mulch and prune the plant to promote new growth.

In summary, pruning and maintenance are essential to keep your Senetti plant healthy and beautiful all year round. Prune your plant regularly to promote new growth and remove dead flowers to encourage reblooming. Take proper care of your plant in the winter to help it survive the cold. With proper care, your Senetti plant will thrive and bring joy to your garden for years to come.

Propagation Methods

Senetti can be propagated by both seed and cuttings. Here are the two methods you can use to propagate your Senetti plants:

Seed Propagation

Propagating Senetti from seed is the fastest and least expensive way to grow large quantities of young plants. To propagate Senetti from seed, you can follow these steps:
