Seed-grown agapanthus will obviously take much longer to flower. This is because apart from establishing themselves they also have to obtain maturity prior to blooming. 

Mature plants bought from cultivators will usually take a minimum of a year to bloom. This period is relatively short because they just have to become acclimatized to the conditions in your garden’s environment. 

But remember, an unhappy Lily of the Nile will not be in a rush to flower! First, it must establish good health, energy, and a steady supply of nutrients. Irregularities relating to soil, sun, water, and weather requirements could put the plant under stress, which affects flowering!

How Many Times A Year Do Lily of the Nile Bloom? 

Lily of the Nile comes in two main varieties, reblooming and non-reblooming variants. Depending on which one you have, you’ll see a difference in flowering. 

How often an agapanthus plant blooms will greatly depend on whether it is a reblooming or non-reblooming cultivar. The former blooms a couple of times over a period of weeks. While the latter will bloom once for a series of weeks. 

A – Reblooming Agapanthus 

A reblooming agapanthus plant will bloom twice (or more times) a year if you decide to deadhead in time. Each bloom lasts a few weeks. 

This type of agapanthus has the ability to start blooming early, at least earlier than the other variant. The first bloom will take place in spring and there will be regular reblooming up until the first frost initiates the winter season. 

But, multiple blooming sessions will only occur if the plants are deadheaded before they drop seeds. After the flowers are spent the plant will concentrate its energy on developing seeds. 

Deadheading evidently plays an important role in dictating how often Lily of the Nile bloom.

So, if you deadhead the flower head, energy will then be relocated towards blooming again. Thus you can experience more blooming sessions all just because of the action of deadheading which almost acts as pruning. 

Wondering when you should carry out flowerhead removal? 

Look to the flowers for telling signs. The bottommost flowers shouldn’t be the only ones to be dry and disfigured. When all the flowers look like these at the bottom, that’s when you know to remove them all (the entire flower head). 

After this, you will be surprised shortly by a new flower head!

B – Non-Reblooming Agapanthus 

The story is quite different from non-reblooming agapanthus variants. They generally do not flower more than once a year. Plus, these appealing flowers will only last a few weeks before they will start to produce pods bearing seeds. 

So, is it even necessary to deadhead non-blooming agapanthus if they don’t even rebloom? 

Actually, there is an advantage or two of carrying out this activity on your non-reblooming Lily of the Nile. 

  • For one, it neatens the plant out. The blooms are eye-catching when they first open. After the flowers aren’t as fresh-looking, they are much less of an attraction! 
  • Another reason is that the plant will drop seeds after the flowers are consumed. This will result in a large number of new plants that are not of high quality. In fact, agapanthus plants are weeds that can be troublesome to control! 

These seedlings will grow into a plant that does not represent the original plant. This is due to over-cultivation that results in plants with completely different traits that are often poorer than expected. They are often invasive and not very reflective of an ideal agapanthus plant. 

There is only one way to avoid these scenarios, that’s by deadheading the flowers.
