Heucheras to make bed studded with jewels

This question was asked by
Rodney

I have a bed in my garden triangular in shape 2.4m long 1.5m wide tapering to a point. The site is full sun (when it shines) and irrigated.In South Warwickshire
I would like to plant Heaucheras/Heaucherellas to give for a while, a series of jewelled blobs, I know that they will eventually join together but I saw a National Trust bed that had that effect, if you think that they are better closer together plan it that way
I have made a list of plants that I like but I would appreciate your advise, as the experts, to help me achieve the effect that I am looking for, and the plants needed.
With many thanks

Hi Rodney
Thank you for your email
As a guide we usually recommend 4 or 5 plants per square metre to give that effect
We still have some of the varieties you mention but not all until next year now but we do have alternatives
If your wanting to get it done this year varieties are selling out fast
There will be more of some varieties in late September but obviously not all
If you can’t order what you want online send a list with how many of each to info@plantagogo.com and we will do the order by telephone
Hope this helps
Kind regards
Vicky
