Hi, what is the difference between the 3 Heucherella’s etc? Why do some suffer rust badly while others seem not to be affected.

Hi Sylvia
Thats two questions! lol

The differences between Heuchera, Heucherella & Tiarella

Heuchera which have lots of colour with a maple shaped leaf, which can be ruffled, with veining etc.
The flowers have many bell shaped flowers on tall/short stems.

Tiarella have lobed or heart shaped foliage which are mainly green with maroon barring in the center. The have star shaped flowers usually clustered together at the top of the stems. Common name for Tiarella is Foamflower because of the way the flower looks at a glance.

Heucherella are a result of crossing the two genus together. Hence the name. As you might expect you get qualities from the two genus.
All the colour usually which comes from the Heuchera, and leaf shapes and often markings from the Tiarella. The flowers tend to be like spaced stars on tall/short stems. Which is a mix of the two again.

Heuchera are more prone to rust than Tiarella in fact I have never seen a Tiarella with rust
When you cross the two genus together that gives Heucherella a little more strength against the disease.
Although all three can technically get rust.

Rust can be sorted very easy by following the information on the website. Located once you’ve clicked into the website (not home page) on the left hand bar under ‘Information’, then ‘Growing tips and information’ heading .

Thank you for asking the question – Hope this helps
