Red Waratah
If you are looking for a plant with impact, Telopea speciosissima with its brilliant red flowers is one to consider.
Commonly called the New South Wales Waratah, it grows well in containers and makes an excellent feature plant in the garden border.
The species itself has red flowers, however pink flowering varieties such as ‘Pink Passion’ and ‘Shady Lady Pink’.
The flowers are large up to 15cm across and long lasting as cut flowers.
Telopea speciosissima ‘Wirrimbirra White’ is a naturally occurring white form. Other Waratah varieties are also available.
How To Grow Telopea speciosissima.
Telopea speciosissima requires a well drained soil to thrive, it is the combination of soil and sun that determine its size as well.
Best grown in part shade or dappled shade, Telopea speciosissima will not flower well in deep shade.
In really good growing conditions, a humus rich, deep and well drained, the New South Wales Waratah will reach over 4 metres in height. The following method of planting works well.
Planting Your Red Waratah
- Prepare the soil well before planting, ensure that the drainage is good.
- In soils without good drainage add extra material to ‘Hill Up’ the garden bed, in wet soils ‘Hill Up’ to around 30 – 40 cm.
- Plant the Waratah in the hilled up soil and water in well using a liquid seaweed fertiliser.
- Mulch around the plant to prevent weeds.
- Fertilise after flowering, each spring and agian in autumn using an organic native plant fertilise, or try aged cow manure and blood and bone.
Top Tips
- A position that is protected from strong winds is recommended, as is good morning sun and some protection from the heat of the afternoon sun. Imagine a 50% shade cloth in the afternoon.
- Give the plant room to grow, use large containers and in the garden plant at around 1 metre to 2 metres apart.
- Replenish the mulch each spring after fertilising.
- Water during any long dry periods, do not allow the soil to dry. So good drainage, good moisture.
Pruning Telopea speciosissima
Pruning after flowering is the secret to producing more flowers the following year, this practice keeps the plant smaller and with a good bushy habit. So more branches equals more flowers.
Look for a healthy bud as far down each stem as you can, and prune to this. If that seems to severe, prune back each stem by 1/2.
Renewing older Red Waratah Plants
Waratahs are a long lived plant, however over time the plant will start to produce less flowers, however this is a plant that does have a lignotuber. This means you can prune it back to ground level and its will reshoot most times. Again do this directly after flowering.
Propagation
You can propagate Waratahs from cuttings, and these are taken in spring. The cuttings will strike best with some bottom heat, so heated propagating mat is recommended.
An easier method of propagation is from seed, fresh seed will germinate with 3 – 4 weeks. The disadvantage is that seed grown plants will take longer to come into flower.
